Hey guys, wondering if anyone has had an expeirience with this kind of noise i have. It's like a clinky rattling noise that seems to be coming from the valve cover. I have no exhaust leaks no holes or cracks in the manifold anywhere and have checked hose, bolt etc to ensure something isn't just rattling. I'm thinking maybe a valve or lash adjuster/lifter? It doesn't start occuring untill the car is revved to about 3k or so then it will come and go. While driving it's usually always there.

The car goes in to get tuned on July 2nd but I just figured I'd try to figure it out myself before hand to save some money if it is something I could possibly fix myself.

Any thoughts/input would be appreciated! Thanks!!!

 

I'm at work on crappy speakers, but that sounded normal enough to me?

You said it happens around 3k RPM. Maybe a vid of the noise at those RPMs?

 

sorry, what I meant was is that once the car hits past 3k once or twice in normal driving or u rev it a few times it starts happening, then that sound appears all throughout the rpm range, even at idle, as heard in the video. It sounds like metal vibrating/rattling to me...

 

Hows the shaft play on the turbo?

 

ughh I had a similar noise last week...my valve cover had a small crack on it.. gl with urs

 

What seems to be the officer problem??

tried getting a tube , a solid one , and put one side of the tube on your ear and the other side of the tube to where you think the sound might be coming from..

if what i heard is true , this technique will let you hear where exactly the sound is coming from...

 

Thanks for the input, I will give it a check later on tonight. It seems like it's coming from somewhere up by the valve cover tho, but of course anything is possible lol.

 

I guess I never really thought of a cracked valve cover contributing to that noise I'll have to take a close look at it and see what i find. The only thing is, is that it doesnt neccessarily make that rattling noise all the time, it's just after the car has been driven or given a few revs. Did yours do the same? Or was it a constant noise?

 

can you put a video up of when your revving it to the 3k mark? Ive got a similar sound but only comes on when i back off from the throttle around 2-3k

 

What mods do you have? That kind of sounds like what my old dual springs sounded like in the head.

 

This is the similar noise im getting from my engine when I rev around the 2-3k range and backing off from the throttle.

What was the problem if you dont mind me asking? I have this issue and just changed out my lifters and fresh oil change, new gaskets, spark plugs, and the noise is still there. Exhaust leak somewhere? I'm at a loss.

 

Hard to tell from video. Lots of noise. Lifters?

 

lifter change got rid of the tick, its hard to explain. Everywhere I look people never answered how they fixed the issue. Everywhere. No on ever follows up. I'm pulling the belt off and checking the pulleys soon. Ill try and answer if I find the issue. The sound though is a loud, really loud rattling noise. Sounds like possible bearings going out on a pulley somewhere. I have a new AC pulley and armature to change. Fingers crossed its a pulley going out. Does not affect the performance of the car and sounds goes away after 3k rpm while driving or idle.

 

Its not a pulley, since turning the car on without the drive belt on the systems still causes the noise. No pulleys were turning. No bearings are being turned. Still have the metallic rattling. Since I'm down here ill change the AC pulley to fix my AC problem. Alternator going bad? Once a few months back my car was idling weird and I ended up shutting it off and wouldn't start back up. Dead battery. Jumped the car and been driving it since with no issue. Was some sort of weird anomaly. The hunt continues...
