for you new 00 dakota owners....since this engine
is the latest and greatest that chrysler has to
offer in the dakotas, i think its time for a board
based on this truck/engine. recently purchased one
myself. 00 dakota slt club cab 4.7l with all the
trimmings. patriot blue. sharp truck but i have my
complaints. what do you new owners think???

    Agree totally. That's why I've not come forth with the speed (de) limiter details... Plus, I like my warranty. The speeds I travel with ruler flat runoffs, perfect/wide pavement & several mile visibility (we call our bushes 'trees' in W. TX) while sometimes reaching 95+ in my weaker moments, are very, very infrequent - and dropping. ALL of my 'higher' speed experience in the Quad is at a WWII bomber base near Pyote, TX. Of course some of us really like serious speed now & again, but ONLY on a race course, and NEVER without SEPARATE help & FULL body armor. Night time is 'out.' We set 'the bar' for our kids, so set it high - I do.

    But swobig, renegade69 and as always bookitty (dang it), are each & together quite correct:
    'Over-driving your speed is the pits.' Quote from a well known old (was IndyCars; now IRL) classmate of mine in our younger years.

    My sole purpose to any of this is the fact that I have a 'bit' of experience in racing (& a few good driving schools), live in a RARE environment conducive to a little speed now & then and like to distribute whatever info. I garner on this amazing truck from time to time... but I am a corporate officer in a racing org. and play by the rules.

    Hey, dittos on the Mont Blanc & sometimes my old Cross standby. And what's that old saying? 'There are old pilots & there are are bold pilots; but there are no old, bold pilots!' Absolutely. O:-)

    keg3 I've only had my Dakota since 10/12/99. Probably to early yet for me to give a complaint.
    Actually still am happy with the 4.7L motor.
    But I do have one small item here that I'll mention. I think I should have ordered the power seat. The reason for that is sometime's the lumbar suport is a little more than what I would like. With the power seat that's adjustable. It's not with the manual seat's.
    One other item is I have not found a lot of after market accessary's for this engine. Partly because it's still pretty new and hopefully that will change in time.
    Ok, here's another one I just thought of. It's a safety item that I think I should mention here.
    The side post frame's on the front/side window is unusually large. Problem's can come up if you are not careful and take extra time looking for traffic to your right and left. I have had a couple instanses where I pulled out into oncoming traffic.Whew! Scares the bejeebies out of you! The way that the mirror's are mounted don't help either.
    That's it for me. Anyone else???

    I love my truck. No problems yet and my only complaint - I occasionally knock the radio controls when I shift into 5th (manual obviously).

    Oh and the 4x4 shifter is too short for me - I have to reach down for it, but that's probably my fault for being 6'2".
  • jwm2jwm2 Member Posts: 43
    Andy, Your going to have to stop power shifting if you want to save the radio control knobs :)
  • andy_jordanandy_jordan Member Posts: 764
    Funny you should mention that. Taking one of my kid's friends home last night, he has just got his licence and he says to me "Gee I wish I could shift like you do".

    Now I grant you I used to do a little racing so I learned how to do it properly, but I don't see it as that much of a skill - unless you want to go through the box at 4,000 rpm in the 4.7 (now that's fun). I guess the prevalence of automatics means the co-ordination of two feet and one hand is becoming a lost art.

    Sorry a little off topic.
  • rasharasha Member Posts: 7
    I have my 2000 Dakota 4x4 with the 4.7 shifted through the 5-spd. I have loved the engine so far. It took a while to get use to shifting at a higher rpm. In very light duty I normally shidt a v-8 around 1500 rpm but my new 4.7 does not like to be shifted less than 2000, I hear evil noises from the drivetrain if I do. This motor has plenty of power and is smooth in its delivery.

    Other parts of the truck are not as nice. but I reserve my complaints and dealer fixes for another post.
  • andy_jordanandy_jordan Member Posts: 764
    Something doesn't sound right there.

    My shifting style varies greatly - usually two distinct styles (one with wife, one without).

    In the 'with wife' style I regularly short shift (to increase fuel economy dear) and have never heard a complaint from the transmission.

    Now I grant you that 1500 is a little low for this engine which is designed to rev high - max torque and max rpm are both over 4000 but you should still be able to do 3-4 and 4-5 at 2000 or so.

    Of course for performance you wouldn't think about it until 3000, but hey who drives fast when you can drive efficiently!!!

    What don't you like? Wasn't clear from your post if they were design faults or problems with your particular truck that the dealer is going to have to deal with.

    I'm glad to see a few people are finally getting their dakota quadcabs. I don't have any experience with the new 4.7l and am a little curious about the gas milage of this engine when mated to the 5spd. I do about an even mix of city and highway driving. does anybody have any numbers to share?
  • andy_jordanandy_jordan Member Posts: 764
    I haven't made a study of exact figures, but in my 4x4 5 spd club cab with the 3.92 rear end and the 31 x 10.5 tires, I estimate I am getting 16-17mpg. That is with a fairly even split of city / highway, maybe slightly more highway.

    I now have 3,300km (2000+ miles) and expect mpg to increase by about 8,000km (5000 miles). Probably slightly more than 17 by then.
  • bpeeblesbpeebles Member Posts: 4,085
    I have the 4.7L with 5sp and measure 17-19MPG with each gas fill (My computer draws graphs and learns my driving habits so it can remind me of upcoming PM activities)

    I have found every time that I remove the oil fill cap that there are water droplets inside this cap. Additionally, there is the telltale white film (and odor) that means water/oil mixture coating the inside of the oil fill tube. I use a paper towel to wipe this up every few days but am somewhat concerned about the amount of water that is coming from the crankcase.

    I realize that this is the area where the PCV system draws vapors off out of the crankcase so any moisture/condensate in the oil will accumulate here. Since the weather here has been below freezing for some time, perhaps this is normal condensation.

    Can others that read this forum please remove their oil-fill caps and see if this is a common (normal) occurrence in the 4.7L? I would be very interested in the results others find.

    #131 of 132: Info from insider.. (jenishcr) Fri 03 Dec '99 (07:46 AM)

    I am a engineer at DaimlerChrysler for the truck
    program and for any one contemplating a purchase of
    one then you should know that the 4.7 V8 will run
    circles around the 5.2 & 5.9 V-8. Actually the
    Dakota R/T with the 5.9 is going to be discontinued
    and replaced with the 4.7 because you can buy a
    normal dakota with the 4.7 right now and it will
    flat out run the 5.9.
  • swobigswobig Member Posts: 634
    for a long time. It's about time!! Hopefully the replacement for the 5.9 will be out next year...

    Have been looking at Dakota Club cab's for the last 3 months. Took the plunge wednesday. 4*4 SLT + in Patriot blue with 2 tone paint, and other options. Beutiful truck. Was going to get the 5 speed but after driving the 4.71 with auto decided to see what dealer would do. They had 60 Dakota's and wanted to make a sell, $52.00 over dealer invoice 22,500 and some change. Easiest vehicle I ever bought. Sales manager brings a note book in with 60 Dakota invoices, says take your pick at 52.00 over. I love the 4.71, very smooth, and lots of reserve power to pull with.
  • jwm2jwm2 Member Posts: 43
    bpeebles: I just took a look at my oil fill tube. It's full of the foam that you mentioned with yours. I agree with you that this should be a concern. It comes from as you said water in the oil. I believe you can get it from over filling the oil resavoir as well. Mine is at the top of the full level.
    I will stop into my dealer here and see what he says.
    easymoney: Bet you must have felt like you were in candyland with any of the 60 Dakota's to pick from. Only problem with that is it get's confusing over which one to pick.
    Patriot blue must be a real popular color. My oldest boy just ordered a Durango with that color.
    I think they do look sharp!

  • jwm2jwm2 Member Posts: 43
    bpeebles: Stopped in the Dealers service this morning. Had a mech. ck. the oil filler tube out.
    So he called Chrysler up. They told him this is normal. Other's are doing it also. Although I was the first one to show this to our dealer. Chrysler says it's from the composite material (the filler tube)and it's location in the engine compartment. So with the difference in temperature is giving it the water. They said just to wipe the foam out. The engine is suppose to be ok. If any is ever seen on your dipstick then of course bring it in.
    Also the dealer said to keep an eye out for any TSB's whenever you should stop into the dealer.
    The mech. thought it could be possable for them to change location of the PCB or change the oil filler tube to someother material.
    bpeebles you are in Canada and I am in Iowa. Is there anyone in a warmer climate with a 4.7L Dakota? Check you oil filler tubes and let us know. I'm curious to see if yours might be ok.

  • quadrunner500quadrunner500 Member Posts: 2,721
    Keeping the temperature of the engine above the dew point seems like a good idea. An engine block heater, or dipstick heater should help here.

    I haven'e noticed this on my Chevy, but that doesn't mean the water droplets aren't condensing somewhere less noticeable. I want some kind of heater for it.
  • keg3keg3 Member Posts: 14
    under "normal" driving conditions, at what point should you change your oil with this new engine. manual says 7000 miles. hell, is that to long or what? any ideas, experiences?
  • jwm2jwm2 Member Posts: 43
    keg3 look at maint. and repair topic starting at 61 for some info on oil and changes.
    Talked to the Dodge mech. this morning about this myself. He personly recommended to me to change my oil now. I have 2k on my Dakota now. He says they still like to drain them early for any shavings and debree. I would like to switch over to Mobil 1. To which he replied that's all what they put in the Vipers.

  • edermaredermar Member Posts: 10
    I've had my 4.7 auto for about 10 weeks (800 miles)and am quite happy with it.I have the bigger tires and heavy duty suspension. I'm dissapointed at my current gas mileage, roughly 13-14 mpg.My oil gague is on high normal. What kind of mileage can I expect once it breaks in? My dealer said it was programmed to idle down after 3000 miles.Also, my intermittant wipers dance to their own rhythm.Anyone else?
  • keg3keg3 Member Posts: 14
    edermar: i'd like to say your gas mileage is going to go up. the worst i'm getting is between 16-17 around town. highway is up around 20 now. just turned 3500 miles. its interesting what you said about the dealer telling you the engine is programmed to idle down after 3000 miles. mine was idling at 6 and is now down to 5. must of idled down somewhere around the 3000 to 3500 mile range. though,i do get a little more of a "rough" idle now that it is down to 5. was thinking about bringing it in, but maybe not.no wiper problems though. slt 4x2 club patriot blue. love the new color.
  • ron35ron35 Member Posts: 134
    I have a Dakota with a 4.7 engine on order and I have been lurking on the Dakota Mailing List for several months and a number of new 4.7 owners have reported the water droplet problem in their filler tubes. Only one post as I recall where an individual reported that this was not a problem and he lived in Florida. From what they have been saying on the DML this appears to be a condensation problem and all the dealers that have been alerted say to keep an eye on it. They add that there might be a TSB out on it in the future. Some of the list members are trying different fixes such as insulating the filler tube. I guess the one thing I don't understand is that this engine has been around in the Jeep Grand Cherokee for over a year; have the water droplets been a problem there and if so what have they done about it.
  • bpeeblesbpeebles Member Posts: 4,085
    I reported the buildup of the water/oil emulsion in the oil-filler tube in this very forum (ref #9).
    I too have spent time browsing the DML forums
    <<A HREF="http://www.cs.fredonia.edu/~stei0302/www/DAKOTA/archives.html">http://www.cs.fredonia.edu/~stei0302/www/DAKOTA/archives.html&gt; There are numerous mentions of it there.

    There is absolutely a build up of condensation in the oil-filler tube on the 4.7L V8 during cold outside temperatures (Perhaps 40DegF and less)

    This is caused by condensation within the engine. (ALL internal combustion engines have this phenomena) However, with the 4.7L, the filler-neck is also the 'uptake tube' for the PCV valve. (Positive Crankcase Ventilation)This means that all 'steam' that rises from the crankcase must pass up into the oil-filler tube. The blast of cool air from the radiator fan cools this 'steam' into the goo (oil/water emulsion) we are finding within the oil-filler tube.

    I have taken my Dakota to the dealer and the service guy was very curious about this goo. He had NOT seen a 4.7L yet (not even for an oil change) He looked the problem up on the 'satellite' and even called his cousin, the service manager at the local JEEP dealer. (Grand Cherokees have had the 4.7L since 1999 model)
    and confirmed it was condensation. He took my name and said he was meeting with DC reps in January and promised to bring it up to them.

    Is it a problem?
    Perhaps... but bear in mind this is one of the very reasons we CHANGE our oil.
    Ref<<A HREF="http://www.geocities.com/MotorCity/2195/engineoil_bible.html">http://www.geocities.com/MotorCity/2195/engineoil_bible.html&gt;
    All engines have this condensation... it just is not as APPARENT as it is in the 4.7L.
  • keg3keg3 Member Posts: 14
    well for those who want to know about goo appearances in your oil fill tube. i've got it, lots of it.
    check your tubes/caps!
  • keg3keg3 Member Posts: 14
    for those of you running your heaters by now, (its damn cold where i'm at) are any of you feeling/hearing a small pulse or thump through your steering wheel, while stopped or idling, with your heater on? been doing it for a while for me, its damn annoying-about every 20 seconds or so and only happens when the heat is on. what the hell is it? ideas, experiences??
  • skipdskipd Member Posts: 97
    Does anyone know what the reliability of this engine has been like in the Jeep Grand Cherokee?
  • bpeeblesbpeebles Member Posts: 4,085
    Do you have AC on your Dak? If so, I suspect you are sensing the AC compressor kicking in/out.
    SURPRISE... The AC compressor is 'enabled' in most of the air-handling-switch positions. There are only 2 positions that DO NOT enable the AC.
    Enabling the AC also turns on the electric radiator fan.

    IMHO, this is a poor design. When I want to remove ICE from the windshield at -40f, I DO NOT want the AC compressor to be coming on. This has been known to damage the AC compressor at these extremely cold temperatures.
    My solution? I have already studied the electrical diagrams for my Dak and plan to make a slight improvement to the design. I want to make the AC on/off a function of a SEPARATE switch. (Just like most foreign automobiles) That way, I can use the defroster without wasting fuel by wearing out my AC compressor or pulling salt-laden spray through the radiator with the electric fan.
    The LAST thing I need at -40f is more air through the radiator!! Instead, A COVER is needed to keep that #&%# cold air out of the radiator so the engine can warm up.
  • gsx750fgsx750f Member Posts: 32
    Thanks for the answer about the engine roar during warm-up. I too am used to having a separate a/c switch. At least the Dak blows a little air onto the windshield when its in the heater mode. Since you have a shop manual, lets all know of you find a way the wire up the a/c on its own switch. I suppose you should be able to wire a switch in series to turn it off when you want to. Just have to make sure its placed in the correct location or only the compressor would be switched and not the fan also. I imagine this will require getting under the dash, oh boy sounds like fun to me. Thanks again, Scott
  • rlholmrlholm Member Posts: 37
    I too am interested in defeating the A/C. I find myself forced to live with the two modes even though I like some of the others better. If there were a moisture sensor, it'd be ok (execept for cold temp dangers), but I doubt there is. Instead I'm crusing down the road needlessly running the A/C and wasting gas after the fog is gone.

    I would imagine the wiring from the up front controls decides which modes get A/C. A switch there should do the trick. If you need help looking at a schematic let me know. (I guess I should go buy the shop manual).
  • swobigswobig Member Posts: 634
    even in cold weather. It helps to defrost your windshield - sometimes heat alone cannot do. I've had several older cars that do this and have never had a problem with the A/C, and I never heard of a problem related to this. I know turning on your home A/C when it's cold outside is not a good thing to do and I think it's because the fan is outside and can freeze so that if you try to turn it on it will not run and burn up. Personally I wouldn't worry about it, but please let me know if there is some reason I'm missing...
  • bpeeblesbpeebles Member Posts: 4,085
    I see it as a poor design for several reasons.

    1) Exactly as you say about home AC ... the compressor is under the hood which is subjected to the extremely cold temps and can freeze... HOWEVER this one will not 'burn up' as you say. Instead there is a 100+HP gasoline engine to spin it instead of the wimpy electric motor on the home system. I have seen AC hoses BURST because of the pressures they are forced to endure under these conditions. Many automobile AC systems just cease to function after a few winters in Vermont because the AC compressor is running CONSTANTLY. (Any of the 'useful' settings on the DAK run the AC.)

    2) I agree in some locals the winters are cold and clammy. Running the AC can condense moisture from the air and help to defrost the windshield. BUT in other locals (Such as Vermont), the winters are cold and VERY DRY. Running the AC compressor is just a waste because the humidity is approaching 0% anyway.

    3) WASTE OF FUEL... this is perhaps the biggest reason to not run the AC when it is not needed.(This is both Financially and ecologically irresponsible)

    You will make your own decision. The shop manual tells me which wire under the dash to install a switch into. Now all I have to do is find time to get at it. I REFUSE to work outside on ANY car when my fingers are frozen. Besides, the snap-apart designs on todays cars turn into CRACK-apart in cold temperatures;-)
  • swobigswobig Member Posts: 634
    I just have not run into any A/C problems in the cars I've owned and it gets pretty cold in Wisconsin too...
  • rlholmrlholm Member Posts: 37
    I live in Seattle. The temp is about 35-45 most of the winter, once in awhile it will get a little colder and we get some snow. I use the A/C pretty regularly to get rid of interior fog and condensation. That said, I do like to turn it off after I'm done to save gas and prevent unnecessary wear and tear. Besides that, my wife complains when the A/C kicks in (lowering the heater temp.), turns the heat up when I'm not looking, and then the A/C turns off and I get cooked. Cold weather danger or not, I still want my own switch like my import cars do.
  • netdocsnetdocs Member Posts: 7
    Keg3 re #0: I'm a new owner (900 miles/10days)'00 4.7, CC, 4x4 (3.92), SLT+, Pat.Blue/Driftwood, 31x10.5 etc., just about every other option except the sway bar and ABS at every corner.

    Likes? the 4.7 for acceleration; mileage (17-19 in mixed city/hwy; smooth, carlike feel; nice rack & pinion; comfortable seats (60/30/40); easy entry to the back of the cab for the dog; handling (I dumped the Goodyears for Michelin LTX M/S..they not only turn corners more adroitly, they're better in the goo and snow than Wrangler RTs and probably will half the treadwear of the Goodyears IMO based on comparisons with both in Grand Cherokees; ability to use foglamps without mains on.

    Dislikes? 1) Giant down thumb for the AC. I, too, want to be able to select when I want it and will probably have to install a switch. 2) That darn clicking noise. And I wonder if it really is the fuel system solenoid since it goes away when I change the HVAC mode selector to floor only 3) Wimpy front bumper clearance/protection for the radiator/trans. cooler. 4)Fold-down console could be deeper, but that's a nitpicker; 5)What isn't for me is that the pass. seat is supposed to slide forward when you toggle the lever on the back of that seat. It does, but it takes Hulk Hogan to move it, even with fresh grease on the rails, then the latch doesn't "remember" your recline setting when you raise the seatback. 6) BAck to the HVAC system, like many American vehicles, there is no fanless fresh air vent setting. You have to run the fan to ge air moving. Nor is there a recirc. setting. Sitting behind a poorly tuned bigrig or bus can be an exercise in breath control in this Dakota.

    bpeebles re several msgs. Is it possible that that clicking noise could be the HVAC coming on/off, as I mentioned above, rather than the fuel system solenoid?
  • rlholmrlholm Member Posts: 37
    netdocs, personally I am pretty convinced from what I hear and what I've read here that the ticking noise comes from a fuel system relay.

    I think the system does recirculate in the Max AC position. I wish there was a better way to switch recirc. in and out when following a noxious vehicle though. Maybe another switch could be added, but I bet it is vacuum controlled. My Nissan has a button for recirc. and a button for A/C...nice.
  • bpeeblesbpeebles Member Posts: 4,085
    I agree with your DISLIKE#5.
    My child is NOT a muscleman and sliding the Pass. seat forward/backward takes a LOT of strength.
    I guess that I am not the ONLY one that finds this annoying. It seems that the 'fur' on the seat has excessive friction between the center 'seat' and the Pass. seat. I thought that the tolerances on my particular Dak were such that the pass. seat 'sticks' when trying to access the rear. I am not alone in this dislike.

    As mentioned above, the MAX AC is the recirculate setting.
  • bpeeblesbpeebles Member Posts: 4,085
    To answer your question. There have been some people that have mentions a RHYTHMIC ticking sound. It has been suggested this may be caused by the fuel solenoids (There are 8 of them... one for each intake)

    Another post mentioned a clicking sound that was 'felt' through the steering wheel at idle. I proposed that this is most likely the AC compressor clutch which is NOT rhythmic. The AC compressor clutch kicks in-out at random intervals dependent on several factors such as ambient temperature and system pressure.
  • netdocsnetdocs Member Posts: 7
    rlHolm #35: Somewhere in either this or another close by topic bpeebles, I thionk, talks about a description in the factory manual on how to insert a switch. Thanks for the heads up re recirc in Max AC. That's not mentioned in my manual!
  • netdocsnetdocs Member Posts: 7
    Tnx...I agree the thump in the wheel is prolly the compressor. Re ticking: hmmm...I've seen the other posts re the solenoid. I still wonder why the ticking goes away when I enter floor mode. I've noticed this especially since my original post, as we've had some "cold" WX here (NC) and so I haven't been quite so ticked off during this cold snap(sorry). (Not as cold as VT 'tho---I used to live nearby in Littleton, NH).

    Re the pass. seat stickiness: Aha! That's the rub. It is pretty stinky design and quality/focus group testing. I really do believe that not many actual employees drive what they design/test as there are too many "little" things that spoil the good feelings about products. But I wouldn't rally rate this as a little thing. A lot of owners will get pretty haired off by that after a day or two of trying to slide that seat forward. We'll file a warranty bug on that one. Of course, it is us that do all the real testing/debugging anyway.

    Off that rant: Here's another nitpick: On my rig, the rear license tag bottom edge rubs against the chrome bumper. A sure place for serious corrosion here near the salt water, or in VT and other places where they use salt on the roads.

    I'm going to try inserting some Saran Wrap between the two surfaces and see what gives. If the seat does, then it may be possible to work around this with some of that stickyback Visqueen they use at boatyards and other places to protect carpet while messy things are being done to the rig.

    Tnx to both of you for the getbacks. I'll get back re the great SaranWrap caper after the weekend (he said optimistically...we're all on 24-hour call re this bloody Y2whatnot).
  • netdocsnetdocs Member Posts: 7
    Messed up the paragraph order...the SaranWrap is for the sticky seat, not the license plate
  • rlholmrlholm Member Posts: 37
    Have been running my heater in floor mode and still hear ticking. Maybe you have something else going on. Regarding the sticky seat, should have got a quad cab. I don't have that problem . Booster stool needed for kids though...
  • netdocsnetdocs Member Posts: 7
    rlholm#39: Gee...stool vs. another trip to the dump...hmm

    Re ticking...do you live in a warm/hot locale?
  • rlholmrlholm Member Posts: 37
    netdocs, not especially warm or cold. I live in Seattle. It's usually about 35-45 in the winter and 80-90 in the summer. It rains all though the winter and up to and including the 4th of July. Then it's awesome until sometime in October. Good luck with your noises. I'm officially ignoring mine.
  • netdocsnetdocs Member Posts: 7
    rlholm: can confirm ticking here is from AC not fuel system since 1) Only occurs when AC is on, 2)does not occur with engine off/AC on, 3) Has not corelation with engine speed as a fuelk pump solenoid would (such as the older Lucas types on British cars.)

    Now that;s settled (at least here) I can ignore it too.

    Agreed, I've spent some awesome holidays in Port Angeles/Townsend, Anacortes, etc.
  • jbauerjbauer Member Posts: 39
    Since you are an engineer with Chrysler what are the engineers saying about this condensation problem in the oil fill tube? Given enough time and enough condensation the moisture will drain into the head then to the oil pan, then be distributed thru the oil journals. NOT good! I would think this could be a more expensive recall item to repair the damage caused from this error in design if they wait too long in developing a cure for the problem than if they address it immediately. Seems like the quick fix would be to go back to the filler cap in the valve cover and put a blank plate over the head where the filler tube is attached.

    As a side note, if the transmission problems are really problems why not suggest that the engineers go back and re-create the Torqueflite tranny. It held up under the torque of the 383's, 426 hemi's and 440's. Many times we can learn from the past. An old saying which rings true many times is this...if it ain't broke don't fix it. Could be a bonus for you if they consider your recommendation. Would appreciate your thoughts on the subjects.

    Does anyone have actual driving experiences in similar vehicles to compare these engines and their associated automatic drivetrains?

    I own a 98 Dakota 4x4 with the 5.2L and am planning to replace it with a Dak. Quad cab or F150 4 door this summer. I have not gotten the chance to drive the 4.7L yet and I was curious if anyone has driven Dakotas with both the 4.7L and 5.2L to compare. I have already read the opinions of those that have the 4.7L so I am mainly only interested in direct comparisons of the two.

    Things I'm curious about...
    4.7L vs 5.2L:
    - in fuel mileage.
    - in felt power and torque (I know what the numbers say, how about how it feels)
    - 2000 4x4 improvements over the 97-99 4x4s (feel of new front suspension and new rack/pinion steering)

    To note something else, when posting messages about mileage, some people forget to post if their 4.7L Dakota is 4x4 or 4x2 / manual or automatic. Please include this information since it makes a difference in the mileage.

    FYI, my 98 4x4 auto, 31x10.5x15 tires, gets about 14.5 daily which inlcudes my highway only drive to work at about 70mph. More city driving on the weekends brings that down even more. Step it down even once a day and average drops at least 1 mpg. Long trips at about 73mph cruise control gets me 15 - 16 mpg. Driving 55 - 60 brings that up to 17 - 18 mpg.

    Thanks in advance to anyone that can compare the 4.7L to the 5.2L with actual experience.

    You must have meant that post<43</A>> for someone else. I am 43notPickups a DC engineer. Please reference my profile. It sure would be nice to get a bonus for recommending design changes for my Dakota to DC ;-)

    I can, however comment on the suggestion of "go back to the filler cap in the valve cover".

    The valve covers on this engine are magnesium and thus, are very thin to save weight. In fact, the service manual specifically says that NOTHING should touch the valve covers. Even a rubber hose or a wire-loom can, over time, wear right through a valve cover due to vibration. I suspect that the properties of the magnesium led to the moving of the oil-fill and PCV valve away from the valve-covers where these items are commonly found.

    Yes they are magnesium. The oil filler setup was changed to ensure a tighter crankcase "seal", to better control pollutants. As we all know, the manufacturers have been under the gun from the feds to produce more fuel efficient, and less polluting engines. Hence, Chryslers first all new V-8 engine in almost 40 years!

    Sorry about making you an engineer for Chrysler..I obviously didn't pay a whole lot of attention to the fact that you were referencing a posting from jenisher. But back to the foaming problem...I wonder if "Armaflex", an insulating material used around water lines, would reduce this condensation problem. Anyone out there tried it ?

    If anyone ever figures this out; I'd love to know; some of these engines have the ticking noise and others don't; mine has had it from day one and is not related to AC; you can hear it at fwy speed; put it in neutral and it will die away; I have the 4.7 with auto; earlier post that there are 8 fuel injector solenoids sounds like the culprit area; where are the solenoids, can they be sound insulated; is there a factory fix.

    Warning, if you loan your truck to someone they will invariably release the hood while trying to get to the brake release; I don't know how strong the second catch is on the hood but I'd bet the hood could blow over the truck at fwy speed if left on the second catch.

    Do you know the properties of this "Armaflex" stuff? (The manufacturer should be able to supply this info)

    I truly believe if the oil-fill-tube is insulated from the cold air blast of the radiator fan, the re-condensation of the 'fumes' from the crankcase would not occur in that area any more.

    I have been toying with trying some type of insulation on my oil-fill-tube and have determined that the following characteristics are desirable.
    • Heat resistant (Must be able to withstand underhood temperatures)
    • NON porous (Must not become soaked if oil is spilled during filling)
    • Flexible (This would make it easier to install well)
    I have also read about one person that fashioned a sheet metal heat shield directly in front of the oil-fill-tube (between oil-fill and radiator fan) This may be another option. If one were to use several layers of thin aluminum, ( Metal flashing as found in Home Depot) It would meet many of the above criteria. The multiple layers would improve insulating qualities if a slight air-gap were allowed between the layers and RTV Silicone were used to 'seal' the ends. Someone who is creative with metalworking would be able to utilize several of the existing bolts near the oil-fill-tube to attach it.
