Hey i have a 1992 sc400 with 194000 miles on it. My sc400 recently stopped running. My timing belt tensioner broke and i drove about ten miles to get off the highway. I have replaced the water pump timing belt radiator alternator everything i could thing or but no luck. My mechanic told me that i might have bent a valve but i was informed that the 1992 sc400 does not have interference engine. so is it true or not.
