I heard all the horror stories about the total engine destruction when a belt goes and how it can cost you thousands of dollars. The reason was that the timing belt had broken and left 8 valves in the incorret position so that they were hit and broken off by the pistons, which severely dented the pistons. The timing belt plays a crucial role in the performance of an engine. have them install the timing belt and start the engine and see what happens. I still owe 2 years so I have no choice but to get this piece of crap fixed.
