I finnally got to start my car after many problems and after it started to warm up it started to make a god awful high pitched ungulating schreeching noise from the rear passanger side of the valve cover. it almost sounded like a loose fan belt. its an early 74 260 and i had just changed the oil not too long ago so its probably not that. it also spead up with the rpm and at idle it does it about 4 times a second.
