Hey all,
96 OHV, 212,000 miles
I've got a chirp every once in a while from behind the dash, usually when passing someone at highway speed, when the engine hits ~2200-2800 RPM. It sounds like it's coming from behind the tape deck, and I've heard it both when a tape is running and when there is no tape in the deck. Same with when the heat/air is on or off. I looked around here and elsewhere and figured it was the Camshaft Position Synchronizer so I replaced that with a Motorcraft CPS as well as the lower intake gasket and everything that goes with that.
The trouble is, I'm still getting the chirp every now and then. It stops as soon as I let off the gas, doesn't always come back right away when I get back on the pedal, and doesn't do it when I rev at idle, only when at highway speed. I thought maybe it was the oil pump so I installed a mechanical oil pressure gauge, but it didn't show any change in oil pressure when the sound came back. I really don't want to do the oil pump but I will if that's what it takes
Any thoughts on what else to take a look at would be much appreciated. Thanks!
