ticking noise?? ya so my 02 Z28 with only 25k miles is making a noticeable ticking noise at idle and when reved up a litle (cant tell if it does it at higher rpms though). is this piston slap? is it normal to happen with only 25k miles? if i were to instal a D1 in the near future would i be taking a chance at something internally breaking?

if it's only at idle when cold and goes away it's usually a lifter trying pump up withoil, if it moves along with rpm all the time it's usually a bent pushrod or loose rocker. ls1 are notorious for the lifter and pushrods noises, my car does the same when cold.

Does it sound like THIS?
This was my car after getting the lifters changed to 'improved design lifters' under factory warranty. It was around 24,000 miles. The new lifters didn't change a thing.
They extended my warranty to 68,000 miles because I complained so much.
It now just turned 35,000 today and makes the same exact noise, hot, cold, idle, when ever. If I rev it up for a minute it goes away for a while and slowly comes back.
This is not piston slap.

After I gave up on the dealer I took the rockers and pushrods out and nothing was wrong with anything, pushrods were straight.
I've also heard a few cars with the noise, a guy I work with just bought a used one, same exact car as mine. He said it makes no noise. He brought it over one day and I sure as hell heard it, not quite as loud as mine though.
Also, not sure if it matters but his is a 2002 built in 8/01 and mine built in 06/02, similiar miles. I know mine has a LS6 block. And I've been told my car runs the 1/4 mile on the fast side for a stock car.
It is embarrasing when old ladies and other people who know nothing about cars say it's making a funny noise. (and GM says it's normal).

I've got the same ticking sound and it definitely sounds like it's coming from #7. In other words, it is coming from the driver's side rear of the motor. I've got new MSD wires, new plugs, checked the pushrods, rockers, valve springs and found nothing wrong. My next step is to check the injectors to see if I have an issue. If I can't giure it out, I'll drive it till it dies then swap in a 402 ls2.

Im curious, how did you know it went bad?? I'm not doubting you, just trying to understand what to look for. I've swapped the plug wires left to right, front to back, and it remains the same, the ticking is coming from the rear of the driver's side.
