I was racing the RSX against a turbo beetle S the other night and right at the end of the racing I hear a noise like a chain dropping on the floor and the car shuts off. Is the RSX an interferance motor? I didn't hear any other noises, no metal-metal contact or anything and when I tried to start it, the car turned smooth but just sounded like the chain came off. How hard is it to get the car back to TDC and put on a new chain. Did I bend any valves? Thanx in advance. BTW I smoked the beetle.
