Replying to: caribou1 (Mar 16, 2009 2:14 am) Like Winter2 I have had no problems. After a fuel filter change and priming I can never take an additional pump on the primer because it is solid no matter how long the vehicle sits without running. Anyone who can pump their primer on a daily basis has an air leak somewhere.

Replying to: winter2 (Mar 15, 2009 6:36 pm) As a clarification for anyone reading this, you do not need to run you engine wide open through the gears to do this. You can do every thing that the EGR valve and the turbo need in 3rd gear lockup saving the transmission and the torque converter.

Replying to: caribou1 (Mar 17, 2009 5:31 am) You might be hearing the turbo control valve as it hums as it adjusts the vacuum to the turbo vanes. |

Replying to: siberia (Mar 16, 2009 3:47 am) I follow Caribou's method of clearing the EGR by turning off the overdrive, stomping on the gas from a dead stop or near dead stop and running the speed to 100 KPH and holding it there for a about ten to twenty seconds. If I fail to clear the EGR for a week or when traffic has been especially bad, then sometimes I must do the aforementioned procedure twice to clear out any accumulated soot. |

Replying to: caribou1 (Mar 16, 2009 2:14 am) On occasion I might hear some electrical noise and I think it is coming from the motor that controls the flap used to shut the engine down more smoothly. I could be wrong and then again my hearing is not the greatest either. As to starting, I do hear a little sound from the rear that lasts a split second when I first start the Jeep in the morning or if it has been sitting all day. I believe that the fuel system is being pressurized in some way. If you try to pull the fuel filter after you shut down the engine and do not remove the fuel filler cap, there is a good chance you will get a little shower of diesel fuel all over the place. The tech at the dealer I use strongly suggested that I remove the fuel filler cap before changing the fuel filter. As to cavitation, if the fuel system does not leak, then air entering or being created by cavitation is very unlikely. One of the easiest ways to get air in the fuel system is to fill the CRD or most any diesel while the engine is running. If you are really low on fuel, it will probably happen. Diesel fuel loves to foam when dispensed from a pump. I saw it happen to a guy in a Ford with a Powerstroke . I warned him and he looked at me like I was from another planet. He filled his truck, got into it put it in gear and after twenty feet it sputtered and died. He could not restart it. I drove away with a smile on my face. |

Replying to: winter2 (Mar 17, 2009 2:59 pm) My engine does not have the EGR air flow valve; I have the older system and my turbo sets it's pressure with a waste gate instead of variable vanes. I have the pre-production version of the one you have. I never get OBD codes on my console; mine is under educated compared to yours  Here is a page of the MY2003 manual describing my EGR system. My EGR is easily accessible, it sits just above the turbo and on top of the engine. I wouldn't get my hands dirty if I had to change it. This is much less sophisticated and highly efficient  http://richard.fortin.free.fr/KJ_diesel/OldCRDengine.pdf
