Engine problems - Ticking sound
I tracked down a ticking noise for weeks with my GTP just to find it was an exaust leak and it was throwing a bank 1 sensor 1 O2 sensor code. A little copper RTV fixed it. just a thought.
I am pretty sure nothing fell into the intake track. The car ran 100% fine after the intake swap for about 1000+ miles and about 600 miles on the converter. I am hoping for it to be an exhaust leak but I have tightened down every exhaust bolt I can find and expected everything real well. I also pulled the plugs and the tips were fine so if anything were in the intake track you would think the tip of the plug would get hit first. Also the noise does not change when the car is cold or hot and it a constant ticking.
What exhaust gaskets are you using?
Manifolds or headers?
Also if something fell in the intake tract it would need to be small enough to pass through the intake valve and seat or it won't hit the spark plug. So if it's something big it's just bouncing around on the backside of the intake valve, if it's something small it usually gets stuck into the piston or head and makes a noise until it's beat a section out for clearance.
Just for the hell of it, put a timing light on each spark plug wire until you find the one that flashes close with the noise.
It's damn near impossible to diagnose a sound without hearing the noise so, it's all you. Go put in some ear plugs AND ear muffs and go see if you can figure it out like that. Kind of pointless right? Can you get a sound clip? can you listen to the one I put up and say if it sounds similiar?

I don’t think something fell into the intake because right when I put the intake on it would be making noise. Remember that the noise started 1000 to 1500 miles after the intake. I will try the timing light ideal and I am working on getting a sound clip. The sound does sound very similar to the noise you posted. For some reason it sounded nothing like you're noise then I put new pushrods in and now it totally changed the noise and it sounds like you're noise and goes away at 1500 rpm's. I put the stock pushrods back in to see if it was the pushrods that caused the change and it still made the sound like you're sound clip. It is weird how the sound went from a sound you can hear at 1500 RPM+ to an off idle sound that disappears at 1500 RPM.

Well it's hard to hear anything with that whistling, what the hell is that? Sounds like a huge vacuum leak. What little of the knocking I can hear sounds like a rod or something going the speed of the bottom end, a valvetrain noise would be half the rpm.
So no I can't tell what that is.
Whats this about misfiring? Is it misfiring?

It sounds like it goes away at 1500 + RPM and the ticking stays steady to a slight increase when you rev from idle to like 1000 RPM. The sound might be getting covered up by the exhaust noise at 1500+ though.

I think your engine may have gotten to HOT while setting in the staging lanes, I had a similar experience with my T/A. I was setting in the staging lanes for a while and when I pulled up to race, I stomped on the throttle and it knocked like a b*tch and puked right then and there. It was hard to restart, but when it did it took 30 seconds or so to clear itself and started running good again. It's only did that once for me and mine had less then 30,000 miles on the clock.
I've never had a miss at idle though, but plenty of popping out the exhaust on cold starts.
Good luck, I hope it turns out to be nothing wrong with your motor.

I think you're at the point where you just drive it till it dies, or if it dies.
No point of throwing money at parts if you don't know what it is and if it will run for a long time. If it indeed takes a dump, then you now know you need a rebuild

. I'm grasping at air. I'm no mechanic, just a fairly new car freak (Fbody especially!) that has been learning a lot about these things since last August. So while I'm trying to help you may want to take what I'm saying here with a grain of salt!
The ticking is not the misfire because it is very steady and will go up slightly with RPM. All plugs are tight and look great. I am going to get it looked at by kirt at vector motor sports on Monday so I will post back what his oppion of the noise is. Thanks for the help anyhow everybody.
Well I got the misfire sorted out but the ticking is still their. I brought it to the tuner and he told me that #8 was misfiring real badly, so I pulled the plug and looked at it real good and noticed that the white part of the plug electrode was broke off and was sliding back and forth. Nothing appears to be missing off the plug or I would say something fell into the cylinder. I put new Delco iridium’s in and the misfire is gone so I am happy to get that straightened out at least. Now to figure out what that dam ticking is.
Same problem from 1500-2000 rpm while under load, no answers on my side and I wish you the best of luck, I am taking mine to infineon and seeing if I can run it in to the ground just in spite of it.

Any luck with your car concering the knocking. my car just started doing that tonight after beating down my buddy's evo... Were guessing a spun bearing but you were talking bout checking the oil for metal shavings ?
