Ticking sound
Hi, just wondering if anybody can help. I bought an '02 Z06 a year ago. The engine shakes a bit after getting warmed sometimes up when at a light or whatever but I've read that's normal. The thing is the ticking noise. I thought it was just at a cold start and had the stealership check it out last August. They replaced the lifters. It still made the noise so I thought it must be normal. But it's not. I finally noticed it wasn't right at start-up like piston slap which is what I thought it was. It happens maybe a minute after being started and seems to go away after being driven. Does anybody have an idea?

My car has made a loud tick that I thought was abnormal since I bought it. Hearing many other corvettes that sound similar, I determined that it must be normal. The LS is a noisy engine, I was terrified at first coming from a world of quiet smooth dohc to noisy rock-the-car ohv.

Have someone start your car for you... take an old broom handle or dowel rod about 3 foot long and as soon as the ticking starts... put one end of the rod on the motor or part you think is ticking and the other end pressed to your ear... keep searching till you find the exact location of the tick and that may help you decide if it's something to be concerned with or not...

I had ticking on cold start up that mostly went away when the engine warmed up. Was convinced that I had a sticky lifter. Before I dove into the engine I checked the exhaust manifold (headers) gasket and found I had an exhaust leak. New GM gasket...fixed.

I have something that sounds exactly like what you're describing.....but it's in my 01 Tahoe. Quiet when I start it, then about a minute into it, here comes the ticking. After about 30 seconds to a minute of noise, then, poof, gone!
