#10919 of 11454 2006 liberty oil drain plug threads
Jul 08, 2010 (12:23 pm)
hello jeep experts,
i think i've seen this come up before. i was just at the dealer and he says my drainpan threads are shot and that he needs a solution for removing and replacing the drainplug that will be secure. he mentioned oversize plugs. are they are viable solution to this problem? is that solution only a short term fix? has anyone had to replace the entire pan? any experience/advice relating to solving this problem would be much appreciated.

A new pan installed was estimated for me to be about $1000. It's not an easy fix.
The pan is soft aluminum and is easily ruined. My dealer messed mine up on the very first change and weaseled out of taking responsibility. The plug failed completely at 36,001 miles.
I had a Precision Tune near my house help me with this. They bore out the hole rethreaded it and installed an oversized plug that uses a regular wrench now for about $40. It has lasted five going on six oil changes and it seems fine. To reward them I have had them do all my oil changes going forward.
I've had to go back once or twice because everyone's afraid to over tighten it including me. They just crawl under and give it a tighten and we wipe it off. We're really careful with it.
The longer it holds the longer I'm saving $1000. If it gives out again, I may pop for it because I still love this CRD. Currently have a little over 70,000 miles.
I have a lifetime supply of new gaskets in a ziplock and I put a new one on with each change just to be safe.

The dealer can reprogram the speedometer-I have seen that several people have had this done.
As to the mileage, it sounds like you either have a leaky EGR or another intake issue.
How is the power compared to before?
You should check the turbo hoses, maybe one is loose or has a small hole.
You might also remove and clean the boost/IAT sensor, if you have a functional EGR it can get really garbaged up and this will affect the boost a lot.

Hello Jeep-CRD experts;
I've owned my liberty for 2 years and put 50k on it without any problems. The only concern was the soot produced during sudden acceleration for the driver behind me.
The current problem started a few weeks ago. The day after a long drive (150miles or so) in the morning I realized the check engine light is on and the vehicle does not have power to go uphill or exceed 80 km/hr. (55 mile/hr). Being a sensor problem I disconnected the power (what I usually do with my gasoline car to get rid of electronic errors). The check engine light went off and the Jeep worked as good as before for a couple of hours before I turned the engine off, upon start the engine light came on again and the same story with power etc.
I took the vehicle to the Jeep dealership in town. They performed the test and came up with "Turbo / Supercharger Underboost" diagnosis. The dealer said that they have cleaned the boost pressure sensor. They reported excessive carbon build up under the boost-pressure sensor (and perhaps in the EGR) and asked me to come
back later for a major maintenance. I ended up going there a couple of times; but I think they do not have a diesel mechanic hence are afraid of touching it so they just waist my time and just are fooling around. My questions:
1: Does anybody know a knowledgeable diesel mechanic in Toronto ( Canada) area?
2: With the symptoms mentioned earlier (under boost, carbon built-up, probable sensor /EGR problem) has anybody have an idea about the ball park cost (min-max) to get things straightened again?
3: I love my Jeep and I am ready to invest and learn basics maintenance. Is anyone aware of relevant DVDs/booklets, maintenance manuals, etc. available ?
Many thanks in advance for your response. Please note, as I said earlier, I'm a just a student (but an interested student) in this.

Find an crackerjack Ford diesel mechanic that has gone out on their own. I did and what a great help.

You may find some repair manuals on ebay, I have seen them there from time to time. You did not say if you were using a diesel fuel additvie. My smoking problem ended fairly quickly after using a good additive. A good mechanic should be found at a Chrysler dealership that sells and services Dodge Diesel Trucks.

I would check the turbo vanes actuator and the little solenoid valve that stands behind your air filter box. The vanes are moved by switching the vacuum on and off. Otherwise your boost pressure sensor could be clogged...

I totally agree. One of the problems we commonly have is the EGR getting fouled up with carbon and soot. It is due to the dirty fuel we get at the pump . We are not at the fuel standards that Europe is at and that the Jeep was designed for. The use of Bio-Diesel burns cleaner and reduces the chances of this happening.
Recently I have obtained a young Mechanic at a premium motors shop who is meticulous and is trained in diesels , who understands them thoroughly.
He is the type of person who is willing to do the dirty work .not just change parts but clean them .
For example When he found I was getting the engine light on it was a an EGR not responding and opening up fully to gain boost pressure..so he replaced it and also "cleaned out the burnt fuel "recirculating tubing " that feeds the EGR because it 's purpose is to recirculate the old exhaust fumes of unburnt fuel and recirculate this fuel back into the engine intake for more power. This tube was full of soot and reducing the flow to the engine ultimately giving the nefarious engine faults.
All of this went away after the tubing was blown out and EGR was replaced.
The service to disconnect the tubing and clean it out was $100 . and needs to be done once a year if you want peak performance. Kind of like a tune up for a diesel.This will extend the life of the EGR ..and increase performance .
Hopefully the use of Bio -Diesel will reduce the soot .
