My timing belt is missing some teeth and needs to be replaced. I was told the the engine is an interference engine and that the valves and pistons are shot and need to be remachined. The total cost for this repair is $4000.00. With over 100000 miles I'm not sure if it's worth it. The car ran perfectly until this mishap. How do i know for sure whether or not the engine is an interference engine and I not being ripped off?

Looking at the Gates Belts Info your engine is an interference engine. The belt teeth shearing off could have caused valve, cylinder head, and/or piston damage.So depending on just what did get damaged the cost could be less than $4000. It needs to at least have the Cyl. head removed to assess the actual damage.

I'm having a similar problem. My car was running fine - the engine was a little louder than normal, so I brought it in, and they told me I needed the timing belt and water pump replaced. After this was done, the car wouldn't start and they said I need to replace the valves. How was this running fine before if they were so shot?

YES YOU NEED TO KNOW THAT, YOU CAN TRY A NEW BELT IF EVERYTHING IS PROPERLY LINED UP (GEARS AND MARKS)...IF IT STARTS AND RUNS YOU GOT LUCKY IN THE CYCLE AND MINIMAL DAMAGE WAS DONE...I SAID LUCKY! MOST OF THE TIME THE VALVES ARE BENT AND PISTON HEADS DAMAGED!
