Run it with the belt off for a minute (do this when it's making noise). If all is quiet it's in the accessory drive system (that is good news), if it still makes noise it could be the cam position sensor. If that's the case get it fixed NOW. If the cam sensor fails completely you could destroy the engine because the oil pump runs off the cam sensor gear. I put up with a squeal from my 3.0L ranger for years. 3 mechanics couldn't find it. I finally tracked it down to the auto tensioner myself and replaced it. 4 years of frustration at a squeal that seemed to come and go with no pattern and all it needed was a $60 fix that took me 30 min to do.
