That's what I thought

I suspected a bearing might be a possibility, although exactly which
one(s) would only squeal under load/acceleration has me stumped. Didn't
think of the throwout - don't know offhand if it's standard or auto,
but I'll pass that on.

Ah, good idea... my Honda Accord had this problem now and then (blasted
'87, last year they made'em with a carb, and about 5,000 different
vaccuum hoses meant it was easy to overlook a loose one

Hmm, true, but maybe that's a pointer (yok yok) in the right
direction... if something on the body/frame is contacting something
moving on the engine when the engine mounts flex under acceleration.
Could also be enhanced if engine mounts are weak. I'll pass that on as
well, thanks.

I don't remember if it's a 6 or an 8; I know it's not a 4. We thought
of a timing belt right off, but it's a chain-drive, and a rubbing chain
makes a very different noise

Thanks again for the suggestions!
