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?
