I had my car towed here when the timing belt on my car broke. They called me and told me I would need a several thousand dollar valve replacement because the pistons probably damaged the valves when the timing belt broke. However, I have a non-interference engine in my car so there is no way that could happen since the pistons can't reach the valves. Either they were trying to rip me off or they are incompetent. Either way, it's not good. Beware.
