Thanks! good luck with it. LK

P.S. Whoever deleted your post should reread "Rules of the road" I can't see where a manufactures link violates any of the rules. LK
A Word About Filtration Requirements
There are few areas more confusing than identifying dirt retention requirements when it comes to air filters. Most vehicle owner’s manuals remain silent on the point. In fact, few air filter manufacturers publish any information as to the filtration efficiency of their filters. This stands in marked contrast to oil and fuel filters where there is a relatively large amount of information regarding filtration requirements and capabilities. Studies have shown most engine wear is caused by particles 10 to 20 microns in size. K&N air filters, like most quality disposable air filters, provide excellent filtration of these particles.
To ensure our air filters provide a high level of dirt protection, we regularly test our air filter designs using the testing procedure described above. Those tests demonstrate K&N air filters generally achieve overall filtration efficiency in the range of 97% - 98%, while some of our air filter designs have achieved levels as high as 99%. The fact that our air filters at times reach overall filtration efficiencies as high as 99% while maintaining high airflow is a testament to the quality and capabilities of our oil impregnated cotton air filter medium.
On occasion we see “new” air filter media’s developed and sold under the premise they provide increased levels of dirt filtration. More often than not, as opposed to quoting specific efficiency numbers, this “increased protection” is described as increased dirt retention capacity, meaning the filter can hold more dirt before requiring replacement. Remember, K&N air filters have always provided a service life in excess of disposable filters and then only require cleaning and oiling for re-use.
We encourage customers to do their homework and be aware of the filtration capabilities of an air filter before they buy. Our own testing has revealed wide differences in filtering capabilities. We were surprised to see some disposable paper air filters with an overall filtration efficiency as low as 93%. We hope we have provided enough information to ensure consumers know what they are getting when they buy a K&N air filter.

Independent Laboratory Test Results
In order to verify our filters maintain filtration levels necessary to protect your engine, we test our filtering media through independent laboratories. The testing procedure used is the SAE J726 air filter test procedure established by the Society of Automotive Engineers (These are the folks who are supposed to know everything).
We have included a detailed example of test results using the SAE J726 procedure. These results are for two individual air filters that each demonstrated among the highest overall filtration level we have achieved with our media.
What's causing it?
Steve, Host
It wasn't our host. I was tired and used a phrase I have read many times. This proves the power of the written word. It is not offensive to me nor do I think or act that way. It was a way to describe the sound. Our host was very sophisticated in the nudge for my phrase.
I have been nudged before and am trying to remember how to rephrase and repost. You know I like to stay here and lurk at other levels of knowledge. Some people badmouth some forums for their restrictive use of their forum or the multitude of posters with no tolerance or an attitude.
Thanks for the link to the K&N forum. I just was compeled to post what I had found, since so many have made claims that may or may not be first hand accounts. Obviously the statements made by a manufacturer are biased, but at the same time, those statements are construed as literal contractural statement in courts. That being the case, it is important, that if these issues are, indeed, first hand accounts, these persons do have recourse and I want them to realize it. Again, thanks for the link and I will be visiting it.

Added a second picture to link at post 3277. The rounded aero muffler sits perhaps a little lower. The engine feels better, seems to easily get up to highway posted speeds and above before you know it. No report on mileage yet. No regrets, would buy it again, aero's web site testimonials report lower egt's. Local experience from the dealer(PS F350) is showing Dodge Cummins reporting the best gains of at least 4 mpg.
Sean, the parts manager at Grubbs Jeep, drove it and got a big smile and started talking cold air intake, even mopar cold air. I got burned with a K & N overoiled from the factory on an E150 5.4 conversion van - don't want to buy any more MAF's.
My guess-tamate would be that you fueled up with some old water filled diesel fuel.
1/giveher a good 16 .oz dose of power service fuel,additive, Stanadyne,or any diesel additive that,will clean injectors ,take the water out,and improve cetane.Do this at a 1/2 tank,as water sits at the bottom.
This should take the water out of the fuel.
Then fill up with a premium diesel fuel,like B.P premium diesel,Shell ultra,or a no.1 diesel fuel of some sort.
2/make sure you are up to operating temperature before getting on the hyway.Your overdrive won't engage until the tranny fluid is up to temp.A hint would be to plug her in at night to keep the oil warmed up for faster warm up time.
3/check all fluid levels.A low level on the tranny fluids would cause a hesitation.
Let me know after a week how you do...
Happy Newyear..

What is your oil filter?
I recommend a biocide like Bio=Bor JF from Hammonds (West Marine stores have it). It also acts as a libricity improver. Use about 270 ppm twice a year. Mercedes had endorced this back in 1980's.
1) Reducing the voltage burnd out the lamps, and they are quite expensive to replace.
2) No one will rear-end you because it's dark and you think your lights are on.
He just changed the settings in the on-board computer.
For all the curious and not to (by omission) cause more conjecture, here goes another try.
The phrase replaced by "tenor" is the sound sometimes associated with small displacement, high rpm engines, whose exhaust is modified and is evidenced by a large shiny canister protruding down below the rear bumper.
Has anyone out there had their cruise control kick out? OR has anyone got a suggestion? I appreciate any ideas, & Happy New Year 2006!
Is it just mine or are all the Liberty's cursed with this annoyance?
Months ago I repeated a story here that was told to me about a diesel tanker that ran away while fueling underground tanks with gasoline(in-law was the driver).
I believe the response I got here was that the flap you hear a short time after turning off your CRD would prevent that. And I never have shut my engine off while fueling up, but I also don't let the fuel level get down to one quarter of of tank-mixing may help if some bad fuel gets pumped in. What are your rpm's when the cruise cuts out?
I don't think it is a runaway event, more like a short or a glitch somewhere.
Time to sign off and join the party-two hours til the ball drops for us in the central time zone.
Mine will drop into 3rd to slow it down on a long hill.
When the speed gets to the set point it will shift back up and go. This may be what you are experiencing.
My March '05 unit has had no EPROM updates and the cruise control completely disengages below 32 MPH. A needed update to the programming will bring that down to a more useful ~25 MPH, someday, hopefully. Does anyone have different results indicating the low-speed cruise control improvement?
Hope it's a permanent condition not related to a holiday lull in business ! The animation can be, and was, overdone. At least as deployed here. See how cool software updates are !
Porty programming is poor deployment, anywhere.
Steve, Host
Thanks. I thought that just turned the lights on and left them on.
I'm a happy camper now!
Happy New Year.

Besr of luck! LK
I have the OEM GY Wrangler STs on my GMC Sierra. Went out in the rain last night for the first time on wet pavement. They have to be the worst rain tires I have ever driven on. I'm going back to the GMC dealer and try for a trade. I have less than 700 miles on the truck.
Do you think it would do better in full time 4 wheel drive?
Dodge Cummins owners manual points out that if you park a running diesel over a puddle of gasoline, the gas vapors get sucked into the air intake and rev up the engine. I did this by spraying some WD-40 down the intake of my (Olds-GM V-6) diesel Cadillac.
How sensitive is a Jeep CRD to having the intake suck in a flammable vapor with it's intercooler? Is there a over rev governor on the CRD engine? (wouldn't be effective if it can't cut off the fuel source 'cuz the fuel is coming in the intake pipe.)
Has anyone come up with a propane kit for a CRD engine yet? (would make it prophane, beat 10 sec 0 to 60's)
Let us know what you think about it.
Thanks! LK
CRD's cylinder head is aluminum on an iron block like the Cadi diesel.
Is there any experience with head gasket leaks on CRD's (too young)?
Coefficient of thermal expansion between the iron and aluminum makes me think about retorquing the head bolts at 80k to 90k miles (about the time we're supposed to change the timing belt)(just a whit of head bolt preload loss on each heat-up/cool-down cycle)
I'll open the intake & exhaust (lower pressure drop) though. I consider that "free" power.
:confuse: LK
I've opened up the exhaust and now I guess I'm riding that train. Here or elsewhere, talk of donaldson filters and aem filters using nano fibers (no oil needed).
I'm open for opinions. Use the air box with a replacement filter, if available, or go cold air without the oiled filters. How does a cold air unit handle the maf sensor.
Caribou1 talked about the air filter and box a long time ago. I didn't think I'd be messing with air flow, sorry caribou1.
All our big diesels have a big red panic button that shuts fuel and closes the air intake. Crankcases have expansion valves to vent the vapors but not let fresh air back in.
My thought on the CRD is that the computer probably knows the rpm and can cut off fuel via computer driven fuel injector solenoids at red line, but if the fuel is from an uncontroled source like gasoline vapors on the ground coming up the intake, the engine isn't protected from possible overspeed. If we realized the problem, we could put CO2 fire extinguisher up the intake (shake a big bottle of soda pop), of course, move the car, wash away the gasoline puddle? All McEiver kind of thoughts for something that isn't very likely.
Our synthetic oil is a protection to some extent in that it doesn't produce as much vapors as it heats up and it's EP properties reduce the likelyhood of cylinder hot spots.
We use 800 gallons of Mobil 1 15W-50 in our 5,000 hp emergency diesels. (Yes it was $4 a quart. Oil change interval based on analysis.)
Were they talking about an early version of the CRD? Because mine is not a V6 and my woman was sold on the fact it was quiet.
I agree that our federal MPG guidelines are crap...No mention that the the MPG is better than 11 on a 4 cylinder. I think that was biased BS!
CR Liberty a miss
CR says that Liberty CRD is one of the misses of 2005. Noisy, slow and poor mpg.
Consumer Reports got it wrong!
Liberty will deliver it's fuel economy rating of 21/26 and will exceed it if driven to maximize mileage.
Acceleration test results show it to be faster, the same, or a bit slower than V6 gas version of Liberty depending on who is testing it.
Noise, OK, I will concede that while the CRD is acceptable to me, it could be a bit quieter and I've driven quieter diesels in Europe.
If I subscribed to CR I would cancel!
What are we going to do about this ??
Maybe write to the editor of CR how disappointed we were about his analysis.
That we have differing results in our jeeps.How about suggesting he pay a visit to our website,and ask us what we think??
As you notice they only drive their vehicles in the city probably to the grocery store,rather than on the hyway.
This is why I am glad to see other critics out there like J.D.power& Associates,who are not so biased .
How I battle the biased is I went to a sign company and got a logo painted on my new plain rear wheel cover,
stating it was a
"Liberty Diesel"
my mpg's,
gallons the tank holds,
, towing capacity and 4X4.
Boy ! did I get a reaction,last summer ...In Canada our gas went up to $5/gallon<$1.06/litre..4.5 litres to a gallon in Ontario and here I was driving around Windsor,
I must have had 12 people stop me to ask how I liked it.
Some were beligerent and didn't believe it,I just said you'll just have to go to the dealership and drive one eh??.
I am hoping in some small way I can influence sales in this awsome DCX product.
Speak Soon...

I think anyone that owns a diesel equipped product should be aware of the characteristics of diesel engines. Governor failures, base explosions, runaway engines are VERY rare. I have worked on tugs through my high school years and after the getting out of the Navy for a total of 40 years and have never witnessed any of these. I have heard stories of old slow speed diesel sinking boats when a base explosion put a hole in the bottom
