Replying to: desmo750ss (Oct 30, 2009 6:33 am) 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

Replying to: desmo750ss (Oct 30, 2009 6:33 am) 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) . |

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."> http://photoshare.shaw.ca/view/13452437393-1256940219-70673/0

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. Thank you, Ian

Replying to: isx (Oct 31, 2009 7:24 am) FYI I am a retired Aircraft Mechanic and also worked for Conoco in my younger days. I would suggest not using it. If your looking to run something lighter use winter diesel and an additive.

Replying to: axelf66 (Oct 31, 2009 9:23 am) We were running Jet A, i'm not sure what the difference is between JP4/JP5, my A&P friends said that Jet A is much cleaner then JP4/JP5, but with out having the stats on both, i do not know what the difference is. Thank you for the help, and answers. |
