350 noise

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

Looks like your first post... Welcome to CHR.

You're not going to get much help without a little more specific description of the "noise" you're hearing... knock, grind, ping, etc. Noise made when hot or cold, or both? Done any work to the car lately?

You'll be more likely to get "good" help with more information.
