Odd squeaking from head

[firefighterwhite89]

i have this odd chirp like squeak that comes from my head once it warms up. not a loud chirp but if you get out while its warmed up and running, you can hear it. i can't figure out where it's coming from. I'm going to put a capful of ATF in the head and see if that has any effect to stop the squeaking. anyone have any idea what this could be by chance?

timing belt rubbing on cover?

Most of my odd squeaks have been pulley bearing related

[firefighterwhite89]

Pulley bearing? You mean cam bearing?

[VIPER1988]

There are no cam bearings in this motor. Are you sure the chirp is coming from the head? Most chirps would be from pulley bearings. Such as timing tensioner pulley or alternator.
