noisy roller rockers, what is considered too noisy?
I heard roller rockers can be noisy. Why is this? What is considered too noisy? I have ford motorsports adjustable roller rockers that i have adjusted 3 times now.. All of my lifters seemed to be pumped up and don't move when I push on the pushrod, could I still have a couple that are bleeding down. The noise seems to fade in and out and is more noticeable at idle. I have a mechanics stethoscope, but i am still not able to pinpoint one particular loud one. Some just tap a little louder than others. I can hear it in the car, over my 40 series flowmasters, but not over the radio. I've tried setting them at 3/4 turn past zero lash and now they are set at 1/4 past zero lash. Have new trickflow pushrods, so its not them. Car runs great and rocker can't be heard above 2 grand. Had it over 5 grand several times and everything seems fine, just that annoying valvetrain noise at idle. I'm running 10w-40 castrol syntec blend oil and my oil pressure is around 50 psi.
