o.k. i give up. 350 chevy, has noise coming from between oil pan and flexplate cover. don't know if its flexplate or main bearing.
any ideas? oil pressure is up. doesn't use oil. converter bolts tight and i can't see any cracks.(not to say there aren't any) automatic, make noise in park or drive.(makes me think main bearing) doesn't make noise all the time. not an exhaust leak. help
