The TB was included in a Goodyear TB Kit... Included Water pump, pullys, reg belt. It was done by a Lic Mec. at a shop.
...sigh... car dies a week after the timing belt is replaced... where have we heard this one before??? Goodyear TB Kit ??? Really?? They make one for the TDI ??????? Where was the belt changed?? Did they lock down the engine when doing the job???? Did they torque things properly???? Licensed Mec. means very little... I know fabulous mechanics who would do this job incredibly well who don't have a Mec. Lic....
I only checked the TB by looking under the TB cover and it seemed solid.
I did not check to see if all the marks were lined up.
If the belt went, it would probably look just fine on top... it's the teeth down by the crankshaft that usually get "lost"... As CCBB said, it would be nice to know if the TDC marks on the flywheel and the slot at the back of the camshaft (you need to remove the vacuum pump) are still lined up... If yes, then there's hope... the "mark" for the injection pump is the hole that can be seen through the pulley if you use a small mirror... it should be lined up with the slot that rotates with the pulley...
Please narrow down your location a bit... we may (or may not) be able to recommend someone local to help you look over the car...
All the best,
PS: when my wife drove our 2001 into a flooded street a year+ ago, hydrolocking the engine, I just bought a used engine for $400 and put it in... (I got a good deal...) car had 478,000 km on it at the time... Are you able to work on it yourself or have a good friend who can help you with this???
PPS: isn't there any type of warranty?? I know it's a can of worms to even go there, but... if they screwed it up... (where have we heard this before???)
