Idle clacking sound
Hey what's going on, my 1999 corvette is making a weird clacking sound when ever I'm at idle. The car has a little over 37,000 miles. As soon as I start to drive the sound stops. Sort of sounds like it has a cam. I'm going to take it to a mechanic Monday but I want to know some things that can be wrong with it.
Thanks!
When I get home I'll upload a video of the sound through YouTube and post the link here.

It could be normal, but I've heard other corvettes at idle and they don't sound like that. It has LT headers and full exhaust if that has anything to do with it.

The LTs are exactly what's making that ticking noise louder...the valvetrain noise resonates down through the larger pipes.
I had that with my brand new 427ci when it went in with my 1 7/8" LTs. It's the first thing I asked about after driving it away from the shop. After a couple weeks it just became a none issue. It was like I got used to it but it never bothered me again, it was like it stopped.

So I figured out what the clicking sound was. I had a misfire and my spark plug wire literally snapped in half and was arching off my headers. Plus a little piston slap
