General Maintenance & Repairs - Tapping sound

Heard a tapping sound coming from the passenger side head when I was recharging the a/c system, sounds like a sticky lifter, what do you guys think? At least my a/c works now :lol: Click on image to see video.

hows your oil pressure?

Good question, how to check? Only have the gauge in the cluster to go by.......don't know how accurate that is. Car has an LS6 oil pump though, Matt put that in when he put in the Equalizer cam in 2005. I just noticed the sound today.

Had low oil....
