My friends 99 Z28 has started to tick it's coming from the pass. side. We were thinking lifter but unsure it has no loss in power. Maybe some other part of the valvetrain the ticking gets louder with more rpms. Anyone got any idea's on what could be wrong?

Make sure the engine has enough oil in it. It could be the lifter or a bent pushrod if he has ever over-reved it.

I had the EXACT same noise last week with my car. I thought it was a lifter so I replaced all of them with Comp R's. Then yesterday, I heard the noise for a few minutes again!!! I was sooo pissed. I know its not a bent p-rod or valve because I haven't had it over-revved since I have had the new H/C setup. It has plenty of oil. I'm in the same boat as your friend, I'm thinkin maybe the stock oil pump isn't feeding the lifters enough oil. Even though oil pressure is 40 psi at the absolute lowest. Maybe this is your friend's problem too. Is his car Modded??
