other ticking sound?

[cozmo959]

ive read all about the lifters ticking and such...i have that problem. but just recently another ticking sound started up its really loud form the passenger side only when i step on the gas around 2000 rpm and above. could be an AC component. does the ac system only start working when i press the ac button. i had this problem on the k8 engine as well. Or could it be something else?
