[Vwdiesel] Bad experience on TDI club

[mikitka]

One thing a TDI owner might do if their engine is in question on this. (Yes
it is an added cost but might be worth doing.) That is having your oil
analyzed. That might help in catching any sever wear issues at hand.  

Case in point. Our 08 Acadia with the new 3.6L VVT engine is killing the
engine oil. I can't go past 4k miles on an oil change, even with running a
high quality synthetic.  There seems to be an issue with the engine design
and since the oil system runs the variable valve timing it is putting extra
strain on the oil.  Maybe something kind of similar in the TDI's?

Since so many have asked:
There "appears" to be a problem with the PD (unit injector) TDI made  
from 04-07.  Some, and no one can seem to quantify how many, of these  
engines are suffering from premature failure of the cam, cam bearings,  
and lifters.  Actually only about 1/2 of them go bad but that is a  
different story.  The cause may be:  poor quality of the metal in the  
cam (manufacturing flaw), asymmetrical pressure on the cam and lifters  
due to the lobes on the cam that fire the injectors (design flaw), or  
possibly use of the improper oil by the owner or even by VW  
dealerships (stupidity flaw)  (VW recommends oil that meets a 505.01  
standard and you won't believe the arguments over this!),  Now, I  
personally have no problems yet but when I get time I do intend to  
pull the valve cover and have a look see.  But, to save time, I have  
listed below the 3 questions I asked on the TDI Club forum and the  
answer I finally got.  The answers are in the form of posts on the  
forum so simply click on them to find out.  BTW I think we got two  
different posts mixed up, I don't find my Jetta "gutless and low  
powered, just the opposite, especially since it is chipped to produce  
125 hp.  Hayden


1) What symptoms are exhibited by a PD engine, during normal  
operation, that would lead one to believe that the excessive wear  
problem has occurred?

2) If I remove the valve cover, what can I expect to see if the  
excessive cam wear has occurred?

3) What parts are necessary for repair and who can supply those parts?

Hope this may help.
