FYI: I am now dealing with my third stock turbo failing, this one lasted less than 40k miles from brand-new... This design is SO BAD... Garrett needs to be made aware of these failures.... there have been a LOT of turbos talked about on this board. That points to a design flaw. BTW: This "brand new turbo" that I bought from a dealer and only has at most 40k miles on it...
Geordi,
Being that I am a new (to me) '05 Liberty CRD owner, with 85K miles, I am taking some precautions that I wonder if you or others have taken.
I bought a new turbo oil supply line, P/N 05142607AA; the oil supply line attaching/banjo bolt, P/N 05142792AA; and attaching bolt copper washers (2 required) P/N 04720713. Many thanks to Sir Sam for the Parts Fiches!
According to one of the turbo techs in my shop, and he has conducted countless teardowns and failure analyses, THE #1 REASON FOR TURBO FAILURE IS LACK OF OIL SUPPLY.
I count four (4) curves and a pipe I.D. of 1/4" for this supply line. Not knowing how this Jeep was taken care of previously, I want to make certain that the oil supply to the turbo is as good as it can be now that I am the owner.
The variable vein design may not be as long lasting as fixed-wheel-only turbos; that is not just a Garrett thing. However, if you are going through turbo failures this often, with new units each time, then I would start looking into other things. The turbo failure is likely the symptom not the cause.
FWIW,
Hoosier CRD
