Roller cam idle RPM

Thanks Moper.I understand what your saying on the oiling mod.Would have been a worthwhile mod to make while i was in there.As for that lifter,its actually the rocker that was notchy.The easiest way to explain i guess would be that you know how when the valve cover is off,you can grab a rocker and rock it back and forth within the lash amount?Well on the intake rocker,#1 cylinder,i could move the rocker a bit but it wasnt a smooth fluid motion,and instead of the rocker falling back down onto the valve,it would stay raised,off the valve tip.So loosened the shaft and kinda moved it over the minute amount i could.That freed it up and it was normal.I had fired up the motor for a friend and the idle was low from us messing with it.Thought i heard a knock.Adjusted the idle and it was gone.Of course the valvetrain is a little noisy through the breathers,so maybe it was that.Im hoping.But thats what i found when i pulled the covers.
