I have a 1989 F150 with a I6 300. I noticed the otherday it had a whine to it. Replaced the serpentine didn't help. Tryed all the pullys thought it was the smog pump, didn't help. I have been looking around at what it could be online and it sounds like it could be a leaky intake manfold, which makes sence since I just replaced my valve cover gasket and had to use make a gasket for the intake. I don't know if this is even possible to get such a high pitched noise out of a intake but if it is let me know, or if someone knows of another common ford problem other than automatic transmission modulator valves and rusty wheel wells. Help me out guys!
