#10643 of 11454 stripped oil pan threads by lube shop
Oct 29, 2009 (6:37 am)
I have a 2005 jeep liberty diesel. Recently I had the oil changed at a lube shop and they apparently stripped the threads on the oil pan. Much of my oil - down to the minimum level was on my garage floor when I noticed oil leaking out from under my jeep. Can I hold the lube shop liable? I had to have the oil pan replaced by my jeep dealer and the mechanic said that the new oil plug that the lube shop put in was so loose that he could move it back and forth. He said if I would have gone over a "bump", the plug could have come out and I would have lost all my oil. Any mechanic who could give me your response regarding liability would be appreciated.

ok, so I now have the same problem (surging and smoking while driving, idling fine) I was able to get home at about 30mph but stepping on the throttle, the surging starts and big plumes of smoke come out.
I followed the thread but did not discover what hobjr's solution was. I read a lot of suggestions but what ended up being the problem? A trucker on the road (that was telling me that I was smoking a lot) told me that it is a clogged fuel filter but I find that unlikely as the problem began suddenly and not gradually.
Thanks in advance

Apparently the striped oil plug seems to come up a lot. I have the same problem but temporarily I sealed it with high temp silicone till the next oil change. I don't want to change the pan because the problem will probably reappear later by the next oil-change idiot. So, I am going to tap it to 1 or 2mm larger and make (or find) new wider oil plug. You can probably hold the oil-change outfil liable if you have receipts. You may have to file a complaint with your State's consumer automotive affairs dept to have some clout behind your claim, or at least threaten them with the reporting.
Not a lawyer so I may be way off on this....

These are my suggestions, for I have had a similar problem. When it lurches I pull over and turn it off, waiting 10 seconds, like re-booting a computer. This often works. To just keep driving I found does not solve anything. I also use a fuel conditioner every other tankful, this seems to really help and little or no smoking.
From time to time I give the Jeep a good long, fast run which seems to clear its lungs.
I would not discount the fuel filter advice. I think the filter does not gradually slow down the vehicle. It gets to a point when it is full or blocked and then you get what you have described. Hope this helps

One item sold by Jeep parts is a replacement plug that instead of a recessed socket has a regular bolt like head. The oil change guys then are dealing with what they see all the time.

Well, It sounds like your ERG valve is stuck. It happens when it becomes to carboned up. To try and free this:
1)Make sure vehicle is turned off. 2)Unplug the MAF Sensor (located on the air filter) Do this by pulling out the red tab (located on the plug) to its stop, then pinching the clip on the plug and removing. 3)Restart your vehicle and let idle until temp gauge show that it is at the normal operating temp (needle pointing up). Note a check engine yellow light will come on which is indicating the MAF sensor is unplugged - ignore for now. 4) At this time try to rev the engine several times. If normal operation begins (no surging) try to drive the vehicle on a short trip. If smoke and surging has ended then continue to drive the vehicle for several days at moderate speeds and moderate distances. 5) The MAF sensor should eventually be plugged back in when the engine / vehicle is turned off. If the problem does not reoccur immediately you may be in luck. 6) Service the Oil with recs below. or replace the ERG valve if the above steps didn't work (expensive).
Basically, your choice of engine oil (too thin) has carboned up your ERG valve and probably your MAP (yes MAP is different than MAF) sensor. Having a mechanic clean the MAP sensor is a good idea (he should use carb cleaner spray on the removed sensor). Also you should start using a a heavier weight diesel oil in the crankcase. If you are in a warm climate (all the time like California) use Mobil Delvac 15W40 or Shell Rotella T 15W40 on a 3K schedule with a good filter like a Puralator (Pure One). If is is a temperate climate use heavy weight in Summer and lighter in Winter. Good Winter Oil is Shell Rotella T 5W40 Synthetic or Mobil 1 5W40. Winter change schedule can be 6K if you use synthetic oils.
I also suggest you buy your diesel fuel from a truck stop that has a large amount of truck traffic. You can bet if the truckers are not buying there is something wrong with the fuel. Word get around in the trucking world.
Good luck and find a non-dealorship mechanic that knows the Liberty Diesel Engine (unless you got bucks to burn) .

Thanks CRD Bullydog, I will try the recs over the WE. I've been using Chevron Delo oil, I hope this is not what caused the prob as I heard great things about Delo. I use it on my vintage motorcycles and has been great.
Also, any suggestions on turbolag? It gets a bit anoying when I floor it and it takes 2 or 3 seconds to respond.
#10650 of 11454 Liberty CRD Oil Plug "O" Ring Option..?
Oct 30, 2009 (2:10 pm)
Having changed my oil the other day it took 3 attempts to stop the oil from leaking from the drain plug. Went to the local dealer to get the copper washer and there had never been any in stock. So much for the dealership changing the washer each oil change.....
I have a oil plug out of a 2002 Saturn which has an "O" ring when
makes a perfect seal each time with little torque required. It appears
to be 1/2 inch fine thread. Am thinking of getting a crd plug and having a local machine shop cut a groove in it for a "O" ring.
Anybody have any info on how deep the groove is in relationship to the height of the ring..?
Here is the link the the pics of the plug I took.">
#10651 of 11454 Jet Fuel in a CRD
Oct 30, 2009 (4:22 pm)
Hello all. I'm new to the forum, but have had my 2005 Jeep Liberty Sport CRD since it was new.
Last year during the winter I was using jet fuel in the diesle engine and noticed only one difference, that being that when it was at idle the temp guage would be a little warmer (still in normal operating temp) then using regular diesel bought from cenex. I was told this was because of the higher burn temp of jet fuel. I didn't mind it because it meant the diesel engine would share its warmth better.
When using regular Diesel in the winter it would take a long time before the cabin was warm enough to take a jacket off. I've noticed this with all diesel vehicles i've had.
I also noticed slightly better MPG with the jet fuel. I noticed it was a lot cheaper for me to get it as well.
I use to work for a small freight airline and when it came time for one of the planes to get a fuel tank inspection i always got a free fill up.
I was wondering what the long term damage, if any, would be from running jet fuel in the vehicle as opposed to regular diesel.
I know that jet fuel is tested and regulated alot better then diesel, think it may have something to do with its primary customer flying, but not sure.
Anyways, i was just hoping for more opinions then A&P mechanics.

I would worry about the lubrication properties in jet fuel. Diesel fuel pumps are lubricated by the fuel. Also the high combustion temps in the cylinder can't be good for the pistons and injectors. I have seen guys melt aluminum pistons just with propane mixture The injectors are about 500 dollars a piece. Just a thought, I know nothing about jet fuel.
