#10657 of 10711 Re: EGR Issues [axelf66] by winter2 Nov 01, 2009 (2:45 pm)
Replying to: axelf66 (Oct 27, 2009 9:55 am) Unfortunately, with emissions standards here to stay, the EGR valve is here to stay until someone comes up with a better way of reducing NOx in a diesel or a gasser for that matter. The issue with EGR failure in a diesel is the level of soot and that is based on the quality of the fuel and how much detergent and/or cetane improver one puts in the fuel.   As I have said in the past, domestic diesel fuel is swill. The Europeans have better quality fuel in terms of cetane and have fewer aromatic compounds in their fuel. Only in CARB land, California, can one get something resembling European diesel. Aromatic compounds contribute to particluate/soot formation as well as low cetane numbers.   I have over 57K miles on my CRD and have only had the EGR replaced one time at 14K miles. With the help of my local dealer and others here on this blog, and especially Caribou, I have not had to replace the EGR. I "blow the nose" at least three times weekly

Replying to: prairiegirl (Oct 27, 2009 9:32 am) Got a question here. Are you sure it is the glowplugs? Have someone check the power output from the battery, especially if it is the one that came from the factory. I changed out the original battery from my 2005 recently and replaced it with a group 34 DEKA battery. The fitment was fine and it has 875 AMPS zero degrees F and 1012 AMPS 32 degrees F. My CRD turns over beautifully.

Replying to: CRD_Bullydog (Oct 30, 2009 8:04 am) I would be very careful about using a non-synthetic oil in the CRD. If you have an engine failure that can be attributed to the oil, you are basically screwed and Chrysler will not cover the repair.
#10660 of 10711 Re: Liberty CRD Oil Plug "O" Ring Option..? [mrmag00] by emp2 Nov 01, 2009 (4:59 pm)
Replying to: mrmag00 (Oct 30, 2009 2:10 pm) I have found that simply slipping the right size O ring on the oil plug seals very well with out needing much torque . The O ring will stretch over the plug with out having to removing it .I found this method after I accidently left off the brass washer and did not want to remove the plug and lose the oil . This method also worked for me after getting an oil change and they left off the brass washer, then tightned the plug to the point that it could have stripped and it still leaked . I believe accidently leaving off the brass washer has been the cause of many stripped plugs when they are over tightened to try to stop them from leaking .

Replying to: shar13 (Oct 29, 2009 6:37 am) Is there any way to know if the brass washer was left off when the plug was stripped . That would help your case . See my message # 10660 . Replies to this message: shar13 (Nov 02, 2009 1:29 pm)

Replying to: emp2 (Nov 01, 2009 5:19 pm) Thank you for your response, I will ask the mechanic at the Jeep dealer who hopefully can tell me whether the brass washer was on or off . Thanks for your help.

Replying to: CRD_Bullydog (Oct 30, 2009 8:04 am) Hello Bullydog, I followed your recommendations and sure enough it stopped surging and no more smoke. As you said, the engine light has come on. One question, I still hear (when stepping on the throttle) a louder-than-normal air-rushing sound from around the turbo location. I heard that for the first time when it first exhibited the surging. Could there be a blown or slipping-off hose that would do that? What is a CAC hose? (as some one else suggested I look for) Also, will 15-40 Delo 400 been the cause of my problem? I've been using it for about 20K miles so far and I thought it is a good product?????

#10664 of 10711 Re: Jeep Liberty CRD Problem [desmo750ss] by CRD_Bullydog Nov 04, 2009 (5:16 am)
Replying to: desmo750ss (Nov 03, 2009 10:01 am) The hissing is because of the excessive carbon in the exhaust and turbo which should blow/burnoff in a few weeks driving with the MAF unplugged. Again, I recommend not driving in an agressive manner with the MAF unplugged.   The CAC hose(s) (Charged Air Coler) usually refers to the hoses from the pressureized/output side of the turbo going to the intercooler to the engine intake on turbo charged diesel engines. It may have popped off (doubtful) or inflated from excess heat and oil until it split (thus emits a hiss when pressurized). The intake air side hoses of the turbocharger are not this problem as it has been using clean air thru the air cleaner. These CAC hoses could be checked by any certified mechanic for free with a visual inspection and could be replaced easily.   A split CAC hose reduces the amout of pressurized air from th turbo to the engine thus reducing power. They should be replaced very soon if damaged.   The oil you are using would be ok for California year round driving on a 3K service interval.   Hey make sure you mechanic cleans your MAP sensor when you take it for the CAC hose check.   Aren't Turbo-Diesels Fun???

Replying to: CRD_Bullydog (Nov 04, 2009 5:16 am) If you blow a turbo hose you will know it as you will have no power.   You may be hearing a little more noise as the turbo may be winding up a little more with the MAF disconnected.
#10666 of 10711 05 liberty economy programer by hemiram Nov 06, 2009 (3:41 am)
does anybody make a programer for fuel economy instead of power? do the power programers help with economy? any help would be nice. i`m getting 22 combined city highway. Replies to this message: caribou1 (Nov 06, 2009 12:46 pm) mdamick (Nov 06, 2009 8:17 pm)
