I have a 1980 Trans Am 301 4.9L Turbo Buick engine with 84k orginal miles. The water pump is five years old, alternator is three years old, the AIR pump or smog pump is new as well as the powersteering pump. As well as 3 new belts. There is a screech sound coming from the engine that is similar to the belt screech you get when they're bad, but this sound is not as high pitched as the common slipping belt. It sounds a bit metallic but no like a grinding piston. The screech sound is heard just asfer idle on the tach, but doesn't rise softly like a worn belt. The belts have been tightened to proper tension and belt dressing has no effect on the problem. I also tried WD-40 on the belts in an attempt to get a reaction from the V-belts while troubleshooting but again no effect. The sound seems to come from around the altenator or powersteering pump. It is not coming from the turbo, which sits at the rear of the engine bay.
Any thoughts to what my problem is?
have the same problem?
