Last summer i hit the revlimiter at 6000 RPM and after that I had a pretty bad valvetrain noise.
At some rpms you don't hear it at all.

During the winter I put in the following parts:
Patriot gold springs
LG G5X1E cam
Comp cam lifters
SLP 7,400 pushrods

Also checked everything else and I could not find anything wrong.

I tought this would help but it did not. Maybe a bit more quiet but not much.

Could it be my roller rockers? even if they look okey.

I have let several people listen to it and they all say lifters.... But I just changed them...

Please help me out. I want to use my car

 

I wrote roller rockers...
I just have the original rocker arms.

 

What kind of comp lifters and by your post it sounds like you did not check preload?

 

I don't know what kind of lifters it is.
Just original replacement according to my local store.
They are just right out of the box. No preload.
(That is above my knowledge)

I just think it is strange that the noise is still there even though I changed almost all things.

Now I'm thinking of buying new rockers. Thats all there is left to change.
