Asking for a friend here, so forgive me if I'm short on details... a friend just picked up a late-80s model Mustang (302 I think, but don't quote me on that) and is getting a squealing noise from under the hood. He says it sounds similar to a belt squeal, but it's NOT the belts, as he's removed them all and the noise persists. Also, it only happens under acceleration.
This is hard to do a Google search on as 90% of searches including "squeal" turn up hits on "tire squeal" :)
Replies to email are appreciated, as I don't check this group regularly. Thanks in advance...
