Ive got a 96 y8 head with brand new head gasket, intake manifold gasket. Factory head bolts. Vtec solenoid is NOT hooked up. Running of a A6 intake manifold and A6 distributor. Y8 timing belt.

Its making a wierd noise as if something were inside my engine. If you knew how one of those vaccum cleaners that are the "vortech" and put a BB inside it, it sounds like that.

I hear the sound from start up all the way to 6.5k rpm. Im afraid to drive it. I have not took the valve cover off to check it. Although its not 100% constant, it is mainly when the throttle is opened wide really fast. A very very slow rev it wont make the noise. Sound comes from around the left side.

Im getting the head work done from a guy I know locally and he owns a "shop". He said he test drove it and it didnt make the noise but when I got it, it made the noise. Hes going to check it out and see what it is, but im wondering if anyone knows what it is because I have the car for a little bit.

any help is appreciated

 

Valve lash out of spec??? Detonation??? Just some ideas.

 

it is most likely detonation because that is a high compression setup if you dont have high enough octane or if timing is out a hair you would probably get detonation

 

Still need help on this! BUMP. All the valve clearances are up to spec, correct timing, doesnt see any pully wobble or tensioner problems, just this weird noise at WOT.

also my gf said she saw smoke and it smelled like gas when i sped up past her.

Any ideas?!

 

adjustable cam gear?
