I have posted before about a slight tapping noise, but now I am wondering why im hearing this squicking sound while it is idling. I have a brand new comp cam .501 lift on it. Could it be my mounts are loose and its actually shacking the engine? i will try and post up a sound clip of it tomorrow.

For engine squeeking noises, I'd look firts at the belts; PS, AC, Alternator/Water Pump. Spray some WD-40 on the belt(s) at idle and if the noise goes away, get a new belt(s).

Could be bearings going south on the above components as well.

Dont put WD40 stuff on belts...simply dribbling a little water on a noisy belt will shut it up...telling u which belt..if it is a belt.

A mechanics stethoscope...Or long screwdriver to the ear on things like the alternator will ID the source and if a Alternaer breaing.

A std Doctors stethoscope held in the engine compartmenr will quicly ID the direction the noise is in.

I found a squeaking noise at idle to be a loose tansmission mount.

But you'd swear it was coming from the front of the engine.
