hey all. ive got a 2004 gto running a MTI G1 cam. its been a few thousand miles since the install and last night it started ticking. sounds almost like pop rocks.
http://www.youtube.com/watch?v=V0VlxHixgxU theres a video of it. any of yal have any guesses? i took the valve cover off and retorqued all the rockers down and everything looked normal. thanks in advance!

you might need a different length pushrod.

i'd bet its a rocker arm check those they like to come lose, one almost completly fell of the stud on my car after the cam while it was on the Dyno

Mine sounds the same when i first start up the car. But after a min and it warms up the sound goes away, does yours go away after it warms up? I checked all my rockers and they were still torqued to spec. Im running 7.4 pushrods and the length is fine. I left one of my powersteering bolts off because it was a pain in the *** and ls1howto sugested to leave it out. But i dont know what the noise is either.

That didnt sound like short pushrod clacking. I say check the rockers.

I don't think that a pushrod would do that either. It almost sound like when the engine is shaking that the header may be hitting something and making the noise. The tick is not consistant so I don't think it's the valvetrain at all.

Mine only does it on start up and after a min it goes away until the next time i start it. Even if the engine is hot and i restart it, will make the same noise for a couple min. then it goes away. I dont think it is an exhaust leak though.

it still makes the noise fully warmed up. ive checked all the rockers and there all fine. in person its louder and really doesnt sound like an exhaust leak. im going to pull the heads tomarrow and checkit out.

Am I hearing it correctly, does it sound like two spoons being played?

Before you take the heads off I'd check all the easy stuff. Pull all the pushrods and make sure they are all strait (roll them on a flat work bench, just like picking a cue stick in a shitty bar). Make sure all your header bolts are tight. Make sure the headers aren't hitting the K-Member or anything else. I'd hate to pull my heads, just to find out I had a loose header bolt!
Good Luck, keep us posted

I know it sounds stupid, but check the plugs. make sure you thread locked and they are tight.

I noticed mine dooing it tonight after a few runs so im going to double check the rockers, plugs, pushrods, and make sure everything is tightend down and not comming loose. Hey briced1 if you find out what it is let me know and i will do the same. thanks

bryced1

ok i took the pushrods out athe same witht he rockers, inspected them, all looks fine. put it back together and it didnt do it for awhile untill i herd it one more time and it stopped. i mean just one single tick on deceleration. any ideas?

Car is at paint shop until tomorrow but then i will check the plugs. But the noise sounds like it is comming from the valve cover on the drivers side. I was thinking it was the powersteering because i did not but that pita bolt back in so maybe it was moving a little.

Hey Long Beach, your problem may be in the AIR system if you left it hooked up after your header install. The one way check valve flutters (ticks) due to the increased pressure from the LTs vs. stock manifolds. Easy way to tell would be to block it off and see if the ticking goes away.

If you disconnected AIR, then disregard.

bryced1

mine came back all the way now. now its a little more a ping noise. i think its something in the valvetrain.

I never thought to check the air because i still have mine so i will try blocking it off and see if that helps. I still havent got arround to checking plugs and rockers again but will do that over the christmas break. Thanks for the heads up BDB
