A.C Milan

Hi everyone

I'm sure someone else encountered a similar problem before but I really couldn't find the thread when I searched..

anyway the problem occurs only when at full throttle , once the RPM goes above 5 the clicking noise ( similar to the noise of sand when hitting the inside of the fender ) . the sound only stays for 2 secs then goes away even if the RPM is still climbing.

The sound is certainly coming from under the hood, and it sounds close to the driver's side . I fell its pretty close to me when it clicks.
note that I've installed an axle back 3 weeks ago , I've no intake no filters under the hood, 100% stock.

I'm suspecting an exhaust leakage ( where the exhausts meets the engine , manifold it's called? )
I've read somewhere that it also could be spark plugs , but if it was then why doesn't the sound appear in lower rpm's ?

anyway I was hoping someone encountered the same issue and figured out the solution.

Thanks.

Valve noise? Do you use premium gas?

we dont have here "premium" , it's 91 or 95 octane , I'm using 95.

I dunno if it's a valve , that's serious trouble right?
I was hoping someone with a similar issue could have an idea.

Ahhh 2IS 300. Different engine. No concerns in regards to gas then? Have you checked TSIB's on your car?
