I have an 87 with 62K miles with an engine whine which I can't
find. It comes from the drive belt side and happens at any speed above idle and increases with engine speed. Other than this the car runs fine except for fast idle that does not work which is probably a bad air regulator. I have
checked the power steering pump, the water pump, alternator, both idler
pulleys, and AC comp . Using s***hoscope I have checked the T-belt at
the cams and the tensioner pulley, and then also checked the
distributor shaft and oil pan. Is there any other ideas or anything
that is specific to this year Max that I missed?

 

could be the water pump prolly need to check the t-belt as well at your mileage its due, but nice find 6xxxx miles is excellent for the year
