Weird ticking.

Ok, here's the situation: I got done installing a FAST 90/90 setup yesterday. After my buddy and I opened it up, I started hearing a ticking noise coming from either my engine or under the car. It speeds up or slows down with the engine speed. It didn't do it right after I started the car, it ran fine for about 10 minutes until I brought it up to about 6000rpm.

I have full oil pressure (50psi) which drops to 25psi at warm idle.

No codes.

I just installed Pacesetters and stock LS6 heads. The car ran fine. Before with 90/90 swap, with the exception of me forgetting to plug in #7 cylinder injector. Whoops.

So, what could it be?

congrats on all the mods!! I would guess its a headers leak. Lots of people have the ticking after they install headers.

It could very well be an exhaust leak, it's just that is happened so suddenly after a race. The car was driving fine for about 15 minutes after I installed everything, then started the ticking after.

If the ticking started after driving it, its probably an exhaust leak.

Check and make sure the headers are sealed well to the heads, and that the collectors are sealed well to the exhaust. Just the engine torquing over from driving it can create leaks. Check all the bolts, gaskets, ect, and try to pinpoint where the noise is coming from. Most often a ticking noise is a result of a poor seal between the manifold flange and the head.

It happen after a race then u might look for a bent push rod.

Ok, I found out the the ticking was two loose spark plugs. There is another ticking now, which I'll be checking this weekend for a bent pushrod.
