oil pressure and adjustable hydraulic valve adjustment

[Mopar to ya]

Get the motor warmed up, back off each rocker one at a time til that valve ticks, then slowly tighten til the tick goes away and then 1/4 turn more. Good to do anyway once in a while, especially if you beat on the motor a lot, like at the drags. Adjusting them can't hurt if done right.

Good luck. I need to fit a small allen wrench in my Comp Cam roller rockers and if the engine is running, that ain't happening. Doing it properly is time consuming, but not that hard. Since the engine isn't running well, I would certainly check them even if they aren't making noise.
