    Amsoil dudes-

    Apologies. Admittedly some of us get a wee cranky when merchandising is incorporated subjectively into threads.

    I'm really not sure how the extra $0.70 - $1.20 per quart of Amsoil is warranted, except through advertising hype and 'value-added'. I'll go elsewhere to research it if needed. This isn't the place. Some of us have vested interests in other products, too.

    Jim,

    To answer question 4, yes it's in Italy. Here is the link to VM Motori. "In 2000 VM Motori, together with Detroit Diesel Corporation, became part of the DaimlerChrysler Group. In 2003 the share packet of the Company was defined as follows: 51% Penske Group and 49% DailmerChrysler Group." I'm a newbie myself so I'll let others more knowledgable and experienced answer the rest of your questions.

    L8r,
    Craig

    Hi! It seems to me that 4300 lbs. is a bit heavy for a "toad". I'd look for a much lighter vehicle.

    Good luck! LK :D

    Fix up the old Wrangler!

    Let's all go to Italy and hold a Jeep Liberty CRD owners group meeting and see if VM Motori will take us on a tour of their plant!

    Hi Jim! I, too, have a motorhome and we pull the Liberty behind ours, plus a motorcycle on a lift welded to the frame of the coach. Either SelecTrac or Command-Trac are excellent. In fact we have two Liberty's, one gas and one diesel, one has SlecTrac and the other CommandTrac.

    Depending on your motor coach's chassis manufacturer, you will not notice the Liberty behind you more than the Wrangler you pull (used to tow one of those too!. In fact, it could be my imagination (or a lower center of gravity on the Liberty vs the Wrangler) but the Liberty's seem to pull a whole lot better and with no significant impact on the motor homes mpg (my unit is on a Freightliner Custom Chassis). Good luck and enjoy. See you on the road!! :D

    Hello whitgallman,

    I changed the oil on my CRD recently at 7K (around half the criteria for Schedule "A"). My thoughts in doing so were:
    1. Engine is new.
    2. CRD was consuming some oil the first 2K (valves were
    breaking in).

    I went out and purchased the Mobile 1 0W-40 synthetic oil and went to the Jeep dealership to buy the oil filter (ouch! was a little expensive). Then had a gas station do the oil change for cheap, as I watched like a hawk. Told them to put in 6 quarts (out of 7) and that I would adjust the level later when I got home.

    This whole thing is probably unnecessary but, it gave me some peace of mind as I want to take care of the vehicle. I will let the dealership do the first Schedule "A" maintenance around 7K more down the road. crddude.
  • whitgallmanwhitgallman Member Posts: 121
    I always have that bit of paranoia about letting someone else change my oil, especially when I use synthetic. They could put in anything and charge for synthetic.
    I bought tires for a diesel Cadi at a place that would rotate them periodically for free. I made the mistake of asking them to grease the chasis while it was on the rack. Well somehow that got translated into change the oil. I saw the hood up and wondered why. I had put Delvac 1 in it a couple of weeks ago. They put their 10W-30 barrel oil in it. Somehow my explitive filter prevented me from pointing out their parental genus & species.
  • whitgallmanwhitgallman Member Posts: 121
    Use a Biocide too. The water that collects in the bottom will support a bacteria that forms solids like a black slime, that will clog fuel filters fast.

    At work we use Bio-Bor JF from Hammonds. West Marine and other marine stores stock it. The diesel fuel guy at Southwest Research says it works as a lubricity additive too. Mercedes and GM supported it in the 1980's during the previous diesel peak.
  • whitgallmanwhitgallman Member Posts: 121
    do you use a brake peddle pusher on the brakes of the towed Jeep? (auxiliary brake system?) Is it required?
  • whitgallmanwhitgallman Member Posts: 121
    Mercedes uses Mobil 1 0W-40 in all their cars, diesel & gas. Daimler Chrysler may have arm twisted Mobil to develop the 0W-40 version of Mobil 1 and are probably under some pressure to provide the market for it to keep it available.

    The Havoline (ChevronTexaco) and the Delo (also ChevronTexaco) could be the same product. Do they meet Mercedes 229.3 as well as 228.5? Mobil 1 0W-40 meets 229.3 and Delvac 1 (5W-40) meets 228.5. The former has less sulfated ash than the latter. (ash comes from Total Base Number additives) the ULSD that the Jeep claims it's designed for don't need as much TBN.

    Sounds like you have a good and honest service department. That helps alot when things go wrong. Good luck,Do you know the build date of your CRD? Its on the door jam
  • crd4me2crd4me2 Member Posts: 26
    Hi all, I've enjoyed the readings, but...
    I'm entering into the 16th week of waiting for my order of a limited CRD. Dealer still does not know when it's due in. I read a few posts about calling DCX to make sure there's no 'hold' on it. Anyone got a number for that? What is DCX (Daimler-Chrysler X?)
    At this point, I'm getting a little upset as it was due in 6-10 wks, putting that mid Dec. I lost out on the Miles of Freedom plan while waiting, and now my trade-in value dropped $3k as we've entered a different year. And I keep seeing a new Liberty on the road every day! Wish I had mine! :cry:

    I did my first service during the week-end.
    The turbo swells oil that collects at the lower end of the hose that goes to the intercooler. This is why my hose is always greasy and collects all the dirt. Some oil was visible on the oil filter cartridge and dripped from the turbo. I checked all screws and hose clamps and found nothing was loose. The engine took 1/2 a quart of oil in 25,000 Km.
    The new oil did not turn black quickly as someone quoted in a previous post. This means my old oil still had enough ability to retain soot (TBN) when I changed it, and confirms credibility of extended intervals with synthetic oil as long as the diesel fuel has low sulfer contents.
    There is an enormous difference in the black soot this oil handles compared to older diesel waste oil: only diesel fuel is able to wash it away, I wasn't able to clean my tools just by wiping with a cloth.
    Now for the fuel filter, I was curious and changed it. Mine is definitely a R20S Parker Racor with a built in heater in the bowl. My fuel filter was still clean after this short use (25,000KM) and the only contaminant I was able to find was a 'pinch' of sand like dry debris that collected in the bowl when I flushed it with the drain plug. Flushing is done by reversing the flow in the cartridge when the fuel lines are disconnected. I hope this can make you feel more confident with yours.
    The turbo oil is fed from the top with a 'banjo' connection using a 14mm hex plug. It's accessible without dismounting anything and visible when you stand in front of the triangle formed by the hood's hinge and the spring pusher that keeps it open. Over the turbo there is a heat shield that's interrupted to give access to this fitting.
    The solid copper oil gasket of the engine sump drain plug has metric dimensions: Id 17; Od 21; thickness 1.25mm.
    Last point: only diesel fuel got my hands clean :shades:
  • scogginsjescogginsje Member Posts: 13
    yep, fixing the wrangler up would be a lot smarter financially.
    Actually, if I just washed it it would be ok!

    Regards,
    Jim
  • unclebubbaunclebubba Member Posts: 80
    Yes, we do use and auxillary brake system (Brake Buddy is what we have). As far as I am aware, in most, if not all, states require brake system on all towed vehilces over 1500 lbs..
  • rnaborsrnabors Member Posts: 25
    I also use my Liberty to tow behind my Motorhome (40'dp,Cummins ISL,Spartan chassis) and I also use the Brake Buddy. Before the CRD I towed a Wrangler and before that a Cherokee. I find the CRD to be a "great" toad and love it for a daily driver.

    Build date is May 2, 2005.
  • winter2winter2 Member Posts: 1,801
    The business with the hose from the turbo to the intercooler bothers me. I am wondering if I should pull the thing from time to time and clean it out? Did the oil that had accumulated in there cause it to fail? The new hose is different as there is a reinforcing cuff at the intercooler end. The clamp also appears to be wider too.

    As for the oil staying cleaner after you change is a testament to the better fuel you have in the EU. USLD will not be widely available in the U.S. until the middle of this year. In the meantime, we will have to put up with it and it's associated problems. When I brought my CRD to the dealer last week, the service advisor who took care of me had worked for MB for some years. He has two older MB diesels and they are in good working order. We talked about the EGR problems on the CRD and he told me that they are failing because of our lousy fuel. Too much sulfur and not enough cetane. He adds cetane improver to his MB's also.
  • crd4me2crd4me2 Member Posts: 26
    Lightnin3,
    to contact DCX at the north plant to check on build status, would I simply call the 1800 number under 'contact us'? I'm wanting to know if there's a hold on mine that was ordered 16 weeks ago! I'm about ready to give up.
    Thanks,
    Michelle
  • caribou1caribou1 Member Posts: 1,354
    If you could see what my EGR valve looks like you would laugh. It looks like a pre-series prototype. During the last service at the dealership I found surprising that the mechanics told me it was not worth the effort of getting an OBD reader. He said there was no combustion control...
    My EGR valve is a 'stand-alone' thing, skinny I would say, vacuum driven with no return of information besides the current drawn by the electrovalve that opens the vacuum line coming from the dashboard via the brake booster.
    It's looking a bit more 'mechanical'and to my taste. I have no NOx probe before or after the catalyser. This may be the reason why my truck works! If something goes wrong, I'm not told :blush:
  • caribou1caribou1 Member Posts: 1,354
    Coming back to the hose, mine looks fine. Perhaps yours is reinforced because it has to compensate for larger engine movement since you are supposed to have new hydraulic engine mounts. This is a first thought.
    If you want to access the bottom hose clamp on the turbo you will be better off using an elevator because it's quite difficult to turn around when the truck is on it's wheels (at least for a person my size ;) ).
    I would appreciate seing how to get the filter housing out of it's position. I pulled like mad on that thing and I'm afraid of breaking something. This would make service really easy and allow to change the bulb in the headlight. I have H4 iodine bulbs in complex surface reflectors. They are pretty good but the Xenon reflectors have a better distribution of light. I often turn off my headlights when I'm passed by european cars at night. Are you still using sealed beams?
  • mdamickmdamick Member Posts: 277
    Since it is not tracked by the OBD have you tried disconnecting it and seeing what your mileage does?
  • winter2winter2 Member Posts: 1,801
    As to the hose, the layout in your engine must be different. The rear part of the hose that comes out of the turbo is easily accessed from the right side of the car with a screw driver and does not require the use of a lift or jack to access. It comes off of the top of the turbo charger.

    As to headlights, sealed beams went out many years ago. The last time I dealt with sealed beams was in the late 80's. I looked at accessing the back of the right headlight. Boy, are you right about that. I will try to get some advice from the dealer on how to pull the air cleaner without destroying it or yourself.

    I drive my 06 CRD Liberty over 100 miles ea. day = 1/2 highway 1/2 stop and go. Just passed 6,400 on the clock. I have a distinct vibration between 52 and 55 MPH. The dealer has changed one of the drive shafts = no improvement, drove another CRD Liberty last week new at the lot, it has the same vibration at the same speed although not as pronounced as mine. The vibration goes away if I put it in neutral and coast leading me to believe it's a drive train problem. Can anyone out there tell me why. The dealer is trying to convince me that it is inherent with this model, Is that true and if so when does the thing come flying apart through the floor board?
  • supertechsupertech Member Posts: 32
    I just upgraded my head light bulbs it was tight but no need to remove air filter housing. It is an 9007 bulb I put in sylvania super white bulbs much brighter,I feel they were a good investment less $20.00 each :)
  • supertechsupertech Member Posts: 32
    I think this inherent with this model. This happens at low engine rpms with converter locked up. You can step on it and it will kick out of overdrive or you can get used to this minor annoyance and enjoy the improved mileage by letting it lug a little. The trick for optimum fuel mileage is not to load the turbo- drive easy and let the torque do the work, not the rpms. I can get 32 mpg on the highway just drive like there is an egg between your right foot and the GO pedal ;)
  • faroutfarout Member Posts: 1,609
    Wow, a lot of questions! I will answer the ones I can help with. I have the Select Trac and the best thing is you can use it on dry roads as a full time, command does not have it. I had a Liberty Ltd gas and traded it in on a Sport CRD. I think the Limited is grate, and offers a lot for the price. The Sport is a good value as well it just depends on what you want in the Liberty. I don't think there is more than 50 lbs difference between the two if that. The skid plates are really a bargain from the factory compared to adding them later, I have them and they don't seem to add or subtract to where I live. The cloth seats clean up well with Dawn dish soap, they are treated with stain repellant, I have not had any light, or light or egr issues. The one thing I would say is having the CRD as a toad, get a more substantial set of tires. The Wrangler ST tires are not worth taking the risk of being towed. The OE tires are only made for very light street city driving. As this is my first diesel I can't say if the CRD requires more or less maintenance.
    I would think the CRD would be a good toad, only you know the condition of your Wrangler, and if it is time for a change or you just want a New Jeep.

    Hi Michelle ,
    sorry to hear that your having to wait so long for your libby.They usually make them in groups of orders. Then ship them in, to where they have to go,with the other vehicles the dealers order.

    Unfortunately there is an order to which they are shipped.
    and reasons why..

    1/Availability of parts made will make a difference thats usually the reason of delays.
    2/Vehicles are shipped in an order..
    Ones that are paid cash,first ..,then ones that have trade in's are shipped secondly.but they don't tell you that.

    You can start with the dealer,
    they have an update status book that's sent to them mid- week to tell them the build staus of the vehicles they ordered.
    They should be able to tell you ,if it is built yet and just waiting to be shipped or not.
    The Dealer also should be able to provide a schedulers number for your area and you can make the calls yourself to Teledo,and have the same luck as my buddy who had to wait and pushed the shipping date up sooner by calling.
    You'll have to your info ready ,including V.I.N.

    It could have been worse ,I heard stories of when the PT Cruiser first came out there was a 6 month wait.
    Because of back orders,and popularity.

    I myself looked around for my Libby and found one on a lot and bought it right away.It was my favorite color midnight blue and chrome.
    Nice...
    Good Luck..
    Speak Soon..

    The business with the hose from the turbo to the intercooler bothers me.

    It bothers me too, a little. I previously posted that the turbo on these things spools up very fast and produces over 23 LBS of boost. That seems like a lot to me on a rubber hose. The turbo-intercooler-intake hoses look and feel like common radiator hoses which normally stand 18 LBS and 210 F for a long period of time when holding water/antifreeze. However, I have read that air coming from a turbo can approach 250 to 300 F, before the intercooler. I have no idea if this is indeed the case on the CRD. Let’s just say, maybe so, maybe not.

    This suggests that for the sake of the hose you might want to back off on the “nose blowing” a little. I’m not saying it’s a bad idea, just, that you may not need to full throttle when you do it. When climbing big hills at 1900 RPM (65 MPH) I normally observed between 10 and 16 LBS of boost – usually 6 to 7 on the level.

    Just FYI
  • dzlmysterdzlmyster Member Posts: 15
    I would agree with supertech on this. I have a 2006 Limited, with just 3300km (I'm in Northern Ontario Canada), and have noticed the same vibration. As you may have noticed under the vehicle, there is a vibration snubber on the differential and also the engine has balancing shaft to compensate for inherent vibration in the 4 banger. If you get the engine in a certain RPM area you will feel the vibration, as it gets into a resonant range to transmit that through the frame to the seat of your pants. Just try to keep it out of that range. Driving here in Canada on the highways, at speeds that would amplify the vibration, would make you an accident waiting to happen, so keeping up with traffic is more important than trying to get the most mileage out of a gallon of fuel.
    BTW, I have not plugged it in yet, and have no problems starting at anywhere down to negative 20 celsius. I think that is 4 degrees F for our US friends.

    All the Best with your CRD
  • jkinzeljkinzel Member Posts: 735
    NASA Gal, I can only speak of my knowledge of diesels from tugboats as I have yet to get a Jeep CRD.
    My understanding is that all diesel engines have a “critical point”, a point at a certain RPM that creates harmonics or vibration.
    Next time you have a chance to drive at that speed, notice the RPM’s. At some other time when parked, rev the engine to those RPM’s and see if you notice any vibration. Because the engine will not be under load you may or may not feel it.
    Good luck and please let us know the out come.
  • iammetalmaniammetalman Member Posts: 4
    "As you may have noticed under the vehicle, there is a vibration snubber on the differential"
    The V6 has this also.
    I ordered a CRD yesterday after talking about it since they were first announced.
  • siberiasiberia Member Posts: 520
    There is no inherent drive train vibration in the CRD! The weight at the front of the rear driveshaft is there to absorb low RPM impulse torque from the engine and the weights on the front of the differential are there to absorb shifting impulses from the big transmission. The CRD 2.8 liter engine is turbo boosted to an effective 6 liter engine and the rear differential might be a little small.

    Why do you think the Ford Power Stroke is a V8? The impulse torque from a 7 liter 4 cylinder, turbo boosted to an effective 15 liter, would pound the stuffing out of the Ford drive train. Or, the drive train would have to be twice as big.

    If a vibration goes away when you shift into neutral it cannot be a drive train vibration since the drive shafts, differentials, axles, wheels and tires are still rotating. You would still feel it if it was in the drive train.

    My CRD runs as smooth as silk at all speeds except for the 4 cylinder “groan” at low RPM (under a load) in overdrive that can be felt throughout the vehicle. My 4 cylinder stick Japanese car has the same vibration to a lesser extent when I floor it in overdrive at 1800 RPM.

    When you talk about a vibration that might shake you off the road you are talking about a vibration that is not inherent to the CRD.
  • unclebubbaunclebubba Member Posts: 80
    No argument about that! If the CRD would have as few problems as my wifes '02'Limited (that would be no problems!!!) it would be even better!
  • caribou1caribou1 Member Posts: 1,354
    I will do so after checking the mileage with the new oil I put in. When I disconnect the EGR vacuum line at idling speed there is no influence. I'm wondering if this is a 'proportional' thing related to the engine load (throttle/pedal potentiometer)?
    My EGR is connected to a 'Valeo' concentric cooler to lower the exhaust gas temperature that's being re-injected. You have a plate exchanger instead.
    When in Parking position, I was able to stall the warm engine that was at idling speed by pressing the gas pedal several times but not allowing the engine to rev up faster than 1200 rpm. I think this opened the EGR too early and choked the engine. At least this test showed me that the valve opens with some delay :sick:
  • caribou1caribou1 Member Posts: 1,354
    I have to check again, but this hose has the connection for the pilot (pressure sensing) line of the waste gate.
    When I look at the whole thing, I could hold it in one hand. The diameter of the turbo is about 4" on the exhaust side and slightly larger on the fresh air side. The oil bushing is roughly 1.5" long and 2" in diameter.
    The main thing is that it works nicely :shades:

    Hello everyone,

    As you know, I have read and commented on this site for quite awhile and am a proud owner of a, '05 CRD with just over 8,000 miles to date. Mile fuel mileage (old fashioned method) has ranged on a per tank basis of 19.x to 23.8 (one time) with most tank averages being 21-22 mpg.

    The K&N filter offered, to my knowledge, required a rerouting and essentially bypassing of the air collection system. HOWEVER, when I went to buy a new air filter due to the filth of the original, they automotive store had a K&N that was the same size as the OEM equipment that simply dropped into the canister housing.

    Has anyone use THIS type of K&N filter. Since I get plenty of performance, did you see an increase in mileage? Its "only" $50 so I wouldn't be out as much as the old K&N's but I am still frugal enough that I don't want to waste the money unless there is a measurable difference.

    Thanks in advance for not pulling out your flame thrower, :shades:

    Its a recyclable air filter that replaces the OEM without retrofitting anything. At some point, you would need to apply oil.

    I negotiated a price of $25,145 for an '06 CRD Limited with the G Package and Trailer Tow. I'm curious how this stacks up against what others have been paying for this vehicle. I am finding it is cheaper than what used '05's are going for on ebay and other online sales forums.

    I am told that they are now putting on Goodyear Wrangler HP All season VSB in a P235/65R17 on the CRD limiteds. Anyone confirm that or have any experience/opinion on these tires. I just wanted to avoid the dreaded ST's but it still looks like I'm stuck with dang nasty goodyears.

    The only other recurring themes I see after reading 3675 messages here is #1 the EGR will go bad and #2 you will likely have to have the computer reflashed at some point and #3 watch out for brake issues

    With the '06's are any of these resolved?

    Thanks!

    I have 10,500 miles on my 2005 CRD and have had none of the above mentioned problems. My ST tires have been fine so far, I have had no traction problems or slipping on wet pavement. They even worked OK on a slightly muddy grass road.
  • winter2winter2 Member Posts: 1,801
    1. EGR may be less of an issue once ULSD appears on the market. My local dealer confirmed that the EGR issue is linked to our crappy domestic diesel fuel and the high sulfur content.

    2. I think the computer flash issue is just about dead. Anything built after mid-May 2005 should be okay.

    3. As for the brake issue, that was with the early builds. I have some noise when I back up in the morning after a damp night. It is either a squeaking sound or a grinding noise. If I drive about 25 feet, the noise is gone. Some people had brakes that bound up, but again that was an early build issue.
  • winter2winter2 Member Posts: 1,801
    Okay people, here is the straight dope from K&N about using their filters in a CRD or a VW TDI. Both have MAF devices.

    1. The oil does not come off of the filter. If any does come off of the filter, it will not harm any sensor, including the MAF.

    2. The turbo will spool up faster, so a lighter right foot is in order, otherwise your fuel economy will drop some.

    I have number 1 in writing (via email) from K&N.

  • nasagalnasagal Member Posts: 2
    Thanks for your response, I have reved the engine to the 1,700 RPM +-, No vibration there, I have also switched the overdrive off at 53 to 54 MPH,,,still vibrates even though the engine rpm's are higher, Place it in neutral while at over 55 mph and the vibration goes away completely as it slows down. I believe the problem is either in the transmission or one of the drive shafts.

    Dear Easter Bunny,
    Santa wasn't good to us.
    Siberia says cummins makes a 2.8 (4cyl?)197Hp marine diesel. Can you put one of these, with no egr needed like the 5.9B, (or better yet build that 2.95B 6cyl w/o an egr)
    and you can put it the bowtie's new half-ton truck with an electro-magnetic locking rear end from eaton. We would really like a nice highway mileage rear end like a 3.55 or maybe a 3.23 and with a real five or six speed tranny we could still trailer with it.
