    Timing belt busted 04 Passat V6 4motion

    Fellow VW lovers,
    Yesterday the timing belt of my wife's car busted and one of the pulley's busted off. It is a 2.8 V6 30v. I put a new timing belt on and a pulley but it wont do anything. The engine is death and sounds like there is no compression at all (very light). The engine turns over but she wont fire. Could it be that i got the timing wrong or are the valves bent? Is there anybody who had the same experiences with this engine or knows more about this topic? Any advise, idea's and thoughts are helpful and appreciated! Thank you.

    The valves are bent.

    Just out of curiosity what is the mileage when the Timing belt busted on your wife’s 04 Passat V6 4motion?

    Yeah you definitely have several bent valves. We will always get bent valves if the timing belt breaks on our 1.8T and 2.8 V6 30V which are interference engines. That’s why it is very critical that the timing belt system components, including timing belt, tensioner, idlers, water pump, and thermostat, need to get replaced at 70K-mile interval on V6 as suggested by Bentley, NOT VW specified 105K-mile interval; as these components from VW won’t safely last over 70K miles. If any of these components seizes or fails, the timing belt is gone too.

    Hopefully your pistons are still in useful shape so that you will only need the head job. Just don’t keep cranking your engine which may cause further damage to your engine. After you have the head job done, make sure to change ALL timing belt system components like this VW Passat Timing Belt Kit.

    Here is a good thread which should help you to get out of this mess:
