[Vwdiesel] Amsoil and stick in cylinder and torsion values on PD

[dieseltdi at verizon.net]

Just as a follow up, I had to go to the dealer this afternoon to pick up a few things so I went to the service department and asked them to print me out the official 2004 BEW maintenance schedule.  Currently VW still has the timing belt interval at 100000 miles.  HOWEVER, the service manager said that if they inspect the belt at 80000, and it looks stretched or worn, they will recommend that it be changed.  So the 80k interval is  a dealer recommendation, not a VW one.  Hayden

First of all the Cam failures are much higher for the BRM engines that the BEWs probably as is stated below due to the different cam profile.  So they have been plagued by the problem.  As far as I was able to get information off of the TDI list, the problem is NOT widespread in the BEW except where the improper oil was used or where the engine was chipped. Although other failures have occurred these cover the vast majority of BEW PD failures as least as far as I was able to determine from folks that reported failures on the list or directly communicated with me. The point that I want to make it that, at least in the BEW, this is not the disastrous problem that many make it out to be.  Secondly,  I would really like to know about the 80K belt change, nothing I have see shows this.  I would also question this considering the kevlar base of the belt but……  So if you have information from VW on this let me know.  When I bought my car it had just had the belt changed at 75K because the dealer had convinced the female owner that it was required even though the service book specifically said 100K.  As I am approaching 140K on the car, I am within a year or so of the 80K so I really want to know if this is the new standard.  Finally, in the timing of the PD engines, I think that the isn't a problem with the "torsion" values when it comes to slop in the timing belt. The computer can easily handle slight variations of timing that are necessary for the engine to run exactly.  Since injection in these engines is ENTIRELY a function of the computer telling the injectors when and how to fire.  I have looked over the specs for replacing the timing belt and I was actually quite surprised to find nothing about the engine timing.  Basically, lock everything down, replace the belt and unlock everything.  You don't even need the VAGCom or similar.  Interesting.  Hayden
