Engine Squeak/Chirp

I have a 1997 Ford Ranger 5 speed RWD with a 3.0L V6 engine. I have had a problem for about two years now of a constant engine squeak. It seems to go away with belt dressing so I figured it had something to do with the belt and the pulleys. I changed the idler pulley, the tensioner pulley, and the belt and it still squeaks. I then thought to check the A/C compressor clutch and it seemed to be coming from there, I sprayed some WD-40 on the clutch and the engine was perfectly quiet. I did this again a few more times and each time it quieted the engine. I was almost certain it was the A/C compressor clutch but after I changed it last night it was quiet, but this morning it started squeaking again. At this point I can't think of what the problem might be. Please post any information that might lead to the discovery of my annoying engine squeak problem.

Sounds like my problem. Engine has 106,000 miles on it, I guess its time. I bucked up and got the Motorcraft one from Rock Auto.

You have ascertain where the noise is coming from. Since yours is the 3.0L, it could be a belt/pulley issue, or it could be a camshaft synchronizer issue.

Okay

Alright, so take the belt off and start it up and if it squeaks, check the Cam Sensor ?

you can also check the alternator- mine squeaked due to dry bearings.

Fixed

My tensioner separated the same day I posted the first time and it was angled out toward the radiator and it was kicking my belt off. I changed the tensioner and the squeak is gone.
