Hi All,

Question. My friend has a 2000 A4 1.8t. She was driving on the highway doing like 65mph when the car suddenly shut off. Tried cranking and nothing. The car was then towed to a dealership and after them removing the valve cover noticed the belt was a little loose. Seems to me the tensioner broke!...

Now, the question I have is this... What are the chances that once the belt goes that the valves bent??.. Do you think I can get away with just changing the timing belt or is it nearly 100% that the valves hit?

Any help is appreciated!!

Thanks,
Chris

 

its a good chance that thye broke i dont know if they all would or just the intake or exhaust ones

 

In my experience, the chances of valves not to be bent while the TB or tensioner breaks - none... I've actually bought my B5 with busted TB. Here are few pics, you'd get the idea:



And the head off in my garage (towed the car)

Yep its probably screwed

 

Your engine just bent over and fucked itself in the ***. Look for a new head/internals and a giplantic turbo for a new begining... For your girlfiend.. Then youll want to be around her more and she'll think its because you like her.[&:]

 

With an interferance engine, when the timing belt breaks, most likely the valves will be bent. If the car has an automatic tranny, there may be a chance the valves are ok, if it is a manual, they are bent. With a auto, the tranny has no load when the belt snaps.

 

Thanks for all your replies!! Much Appreciated!!
