I have a 3.4l. i just did a comp cam with flat top lifters, and have comp roller rockers. When adjusting the valve lash by adjusting the rockers it ticks when i start the motor. I have put the roller rockers to stock spec and it seems to back off when i start the car? Does anyone know if i need top tighten the rockers any tighter the stock spec?

Re: Rocker arm problem?
They are not self adjusting rockers. and there is no tq spec! The manual says " reduce the play from the rods ( meaning tighten untill the rod can not turn) and then give it one and a half turns! which seems right because it is snug and feel good untill i put the whole motor back together and find out it still ticks!!! Im going crazy.

Re: Rocker arm problem?
whats up greg.
i know exactly what your going through. and it sucks cause it took me and my friend forever to figure it out.
but what you have to do is. turn the engine over. to the COMPRESSION side of each cylinder. and adjust the exhaust and intake valve rocker arms accordingly.
its like they will be snug then when you run the engine it seems loos again. thats because when you tightned them the first time. you didnt tighten them on the COMPRESSION side.
hope that helps man
