What kind of noisy? Is it muffled, like if you put your ear to the valve covers you can hear it, or a loud clacky kind of noise? Mine got quite a bit noisier with my recent cam install!fasterdamitt said:I just got my motor together and I have .045 preload on the hydrolic roller cam with Motorsports full roller rockers. Still noisy, is this ok? Comp Cams says I'll still have noise roller rockers.
