Need help with changing timing belt in 1987 325i. The belt broke. Do I need to worry about valve damage?? Or can I just change the belt???

if your timing belt blew off, your engine is probally screwed. Did it die after it broke? Because if so its probally because all the timing went to hell and you probally smashed up some valves, maybe cracked a piston head, blew your head fa-sho... anyhow, take it by a mechanic for a good estimation on what is wrong. I'm just making an educated guess based on previous expierence. :-x

Of course it's going to die(stall) due to the fact that the valvetrain is no longer in syncronized with the crank. IE piston valve collision , due to M20's are interferance engines.

I'm afraid everyone is right. Chances are pretty good that your engine is FUBAR. However, if you have the time and $$ you can still salvage the engine.

Drive on, Bimmerheads.

I bet that you might have smacked a valve but the engine is not FUBAR due to this.. replace the bent valves when you take the head off. examine the piston crowns, look for damge and follow the Bentley service manual instructions.

There is no need to replace a engine for a Timing Belt snap. Just make sure you replace the belt every 4 years or 40k miles. It only takes three hours.
