I have an 86 325es with the stock eta motor other than a chip. Earlier this summer I changed the timing and other belts but am now running into a problem. Under heavy acceleration (everything but 1st gear) over 3k rpm there is a squeal that occurs. Under normal acceleration it doesn't appear, which is weird. I have checked the tightness of the belts and they all appear to be OK. Is there something else I may be missing or are the belts just not tight enough?

Strange Squeal Over 3k RPM/Heavy Accel

usually a squeal is a bad belt, loose belt, overtightened belt or bad pulley. could also be power steering causing havoc. is your steering normal? a bad pump seizing up would cause belt squeal.
