Well, it's a sad day. Yesterday the CRD broke down for the third time. From recent experience with the same issue, for some reason one of the valves gets plugged up and recirculates diesel/oil back into the intercooler and i/c hoses. The intake hose basically gets lubricated by the oil and won't stay on under boost. I've read about similar problems on the forum. Last time, the dealership said they put a newly designed valve on that was less likely to get clogged. Right now the Jeep is sitting at a different dealer waiting until Monday to assess the problem.

Either way my wife is convinced it's the exact same issue and said she's not comfortable owning the CRD even if they say it's fixed 100% and will never happen again. She admits she enjoyed driving it, but driving 200mi daily isn't very comforting when the vehicle could break down at any time. I can understand that. So in the end she said we're getting rid of it. She wants a Limited Liberty 2wd w/ a gas engine.

I'm so sad...the CRD was going to be mine in 6mo. Now I don't know what I'll be driving. There's a chance I could get my 95 XJ back with RE 5.5" lift and 33's. I'll have to wait and see. Anyway, I wanted to thank everyone on the forums for the help, advice, and stories. It's been great lurking for the past year. Keep up the good work. I'll be checking in on you!

Mike, I hate to see an otherwise satisfied owner get rid of a rig because of a design flaw (and that's exactly what it is...). How many miles do you have, where did you take it, and what exactly did they do? Ultimately, the only way to "solve" the problem is to put an filter on the CCV or vent the hose to air, the former being the environmentally conscious method. The additional plumbing and a provent filter has worked excellent on mine. ALSO, if the dealer has been overfilling your oil, that'll exacerbate the problem (greater volume of oil than spec. tends to have a bit more blow-by). I've only found one dealer in GA that I trust and that's Jasper Jeep. I also trust myself and I'm not an hour drive, so I end up doing most of the work instead of making the drive. If the dealer explained the issue as a "clogging valve" then you should definitely run away. That is simply not an accurate explanation. At the very least, the dealer should have replaced your hoses and given you a thorough cleaning of the fittings and possibly the intercooler. Since there's no "factory approved" fix, all they'll ever be able to do it replace things damaged by the problem, which stinks, but is the state of the industry.

I took all the hoses and "washable" fittings off and soaked them in a rubber-safe mild degreaser and have had no oil in the pipes since I put in the bypass. I'm in Atlanta and can assist if you're not into the whole "adding pieces to the engine" thing. Give it another go, though. Folks here will gladly help and it's free, friendly, and honest help. Better than most warranty coverage you could hope for.

My sentiments, exactly - suggestion: do the Provent mod, drain the condensate regularly and that problem is solved - at 200mi\day, check it daily for a bit to determine the necessary interval, which should be ~once weekly for that mileage accrual.

The problem is caused by the abnormally high crankcase pressure pulses that exist in all 4 cylinder engines, and which is even greater in a Diesel 4cyl - solution will require an external condensate chamber, such as the Provent or Racor - properly installed, the preciptitate drains back into the oil pan, rather being drawn into the intake for combustion, so it fits within acceptable emissions scheme

Some are installed open-ended - some are installed capped, requiring regular drain intervals

If your gonna get a new Libby, push for 4x4. You know you will kick yourself later if you don't.

The overfilling with oil is a chronic problem with CRD's. Chrysler's dipstick is about 1/4" short, so when the correct amount of oil (6.4 quarts) is added the dipstick reads 1/2 full. If you change oil and fill the engine to the full line on the dipstick, the extra oil will be promptly pumped out through the crankcase vent and into the intake, which causes problems. I'd recommend filling it with new oil to no more than the middle of the dipstick range when the oil is changed.

I have a Provent which drains to a container on my CRD, and these comments are based on the amount of oil I drain out of the Provent separator between oil changes.

I fill my CRD with 6.5 quarts and a new Mopar filter. It shows about a quarter of an inch below full and it stays right there. Never had any issues with this amount. The mopar filters are big and absorb a lot of oil. I think the NAPA filters are a tad smaller.

I've used NAPA Gold and Purolators on mine... same size as the Mopar. Frams are smaller.

Now you can keep the CRD and tell the techs the 'easy" fixes

Does that 6.4 include the filter?

Great I just changed the oil in my Fiance's CRD a few weeks ago and noticed it registering low on the dipstick with the 6.4 quarts added so I added additional until it registered full on the dip stick. Now what? Will it be fine until the next oil change?

It makes allowance for the factory filter. If you use one with smaller or larger volume, adjust accordingly.

If you know how much you added past full, just put a oil suction pump in the dipstick tube and remove the same amount (or drain it if you have a fumoto).

Well she's been running for about five weeks now isn't it a little late for that. How do I know if there is a problem? I really don't want to screw with this. I don't have a pump to pump it out of the dipstick and don't have the drain valve either. Why the hell is there a dipstick if it isn't accurate.

By now, it's probably blown a good bit of the excess into your intake. An easy way to check is to pop off the intercooler hose at the IC on the warm side (right in front of your left hand facing an open hood) with a screwdriver or hex driver and some paper towels. You'll see oil residue inside the hose. It should be mostly dry. If there's a LOT, then it'll still be moist in that hose after the engine cools.

If you check your oil now, does it show a little low on the dipstick?

I'll check it tonight and post back tomorrow. We'll go from there. Thanks for the help.

Uhhhhhh confusing nested quotes ... :wink:

If I fill mine to the full mark on the dipstick it quickly gets used up and the level drops to midway, where it stays. With the oversized filter it's 7 qts to the middle.

What do you mean by oversized filter? I purchased the Napa Gold. I just told the counter chic (hottie) I needed a filter for the 2.8 diesel. Also you say when the dipstick shows full it quickly gets used up? Where does it go?

Sorry it's taken so long to post the news. A nice 12hr day at work will often prevent quality time with the computer. The dealership, Nalley Chrysler Jeep in Roswell, said it's the turbo!!! The turbo will be replaced under my extended warranty and/or possibly the drivetrain warranty. BTW the dealership does come recommended from this forum under the Sticky. And, they were not the ones who diagnosed and fixed the vehicle the last time the intercooler hose blew off.

First, let me thank Dan and everyone else for the words of encouragement. Dan, I will definitely be contacting you shortly to add the necessary hardware (Provent or Racor) to prevent any similar issues. I will also be adding a turbo timer to ensure the new turbo is treated with the utmost respect and proper maintenance.

Second, let me ask: what other mods would you guys suggest to ensure the longevity of the motor/turbo since this is the reason for the purchase of my CRD? Let me add that my extended warranty will be covering the vehicle up to approx 107k miles. I don't want to void it.

Third, the Jeep has about 68k miles on it now. It will have 85k within the next 6mo.

Fourth, I need to feel comfortable with my wife/family in this vehicle, especially since she drives 200mi/day. After looking into it with a little emotion removed, we will be keeping the CRD. Although, neither of us feels real comfortable with that at this time. SO I'M NOT GOING ANYWHERE and I will continue to be a member here!

Thanks for everything,
Mike
