I am assuming front. If you have just a cat back I would say the factory exhaust manifolds and y pipe should be tight enough. But you never know. I think it could be a leak like CATransam said, or a bad lifter(s), a bent pushrod(s). Hopefully not a bearing because that would be very bad. What is the oil pressure like? If I were you I would start the engine, pop the hood and try to listen under the car. After its warm have a friend get in and rev to 4500-5000 while you listen under the hood to try to pin point the noise. -- Dan 99 Z28 M6, No Options, Free Ram Air, SS ELiminator, TB Bypass, Holley Power Shot, SLP Air Lid, Vortex Muffler, FTRA, Pro 5.0 w/short stick, Mac Headers w/Carsound Cats, !EGR, NGK TR55 plugs w/ Taylor wires, LS1 Edit Tuning and K&N Breather. 321.69hp, 331.91 tq.  Posted By: ScreaminEagle77 On: 08-01-2006 @ 02:53:48 Reply | Top | Edit well today I let my wife hear it and it just kinda sounded like a "jingling" noise, kinda like if you very casually jingle your key's in your hand,I take the plastic bag comment back. -- Been here since '01.

Posted By: italianstalionjk On: 08-01-2006 @ 11:23:01 Reply | Top | Edit Hey you might need new rocker arms. mine made a ting sound at high rpms and then i found needle bearing in my drain plug from my rocker arms. I think it might be that. Sounds excalty like the problem i had. and it cost me about 700 to put new harland rockers in. -- Black 98 Formula with 49k.

LS1's are prone to this if they are over revved. I spun a bearing in my '75 and it sounded more like a dull knock at high rpm's than a tick. A bent pushrod won't kill the motor quick. A spun bearing will get worse very fast.

If not, it could be spark knocking? You said it sounds like jingling keys, spark knocking sounds like a bag of marbles being knocked around or something like that. I've only heard it once in my uncle's car though. Posted By: ScreaminEagle77 On: 10-03-2006 @ 06:16:07 Reply | Top | Edit Well a little update,it doesn't do it anymore!I put it in neutral got it up in the rpm range and nothing, then I did it from a 20 mph roll and it still didn,t do it. I guess it was just a flook or something.Thanx for the help guy's. -- Been here since '01.

Posted By: 94fireturd On: 10-23-2006 @ 22:41:01 Reply | Top | Edit sounds like carbon build up causing "pinging" or detonation. some times a few WOT runs can knock out the carbon build up and fix this pinging problem. you could also use a top end cleaner like seafoam or amsoil top end cleaner. both work great. do a search on how to use these products. One more thing. buy a can of non residue parts cleaner and spray the little filliments of your MAF. but dont toutch them, they are fragile. if you have a k&n filter, the purple oil will build up on the MAF and can cause the car to run bad. --
