There is no adjustment. If you have the type of rocker arms with lock nuts, the best way is while engine is running tighten to 0 lash (rocker is no longer making a tapping noise) than go an additional 1/2 turn. If you have regular nuts there is no adj. torque nuts to 25 ft. lbs
There is no valve lash adjustment (per se). Torque the rocker arm fulcrum nuts to 23-29 ft. lbs.
There is no adjustment. Rocker arm nuts/studs are torqued down to specs and that's it. If they are clattering you have worn out valve train parts.
You don't. The nuts that hold down the rocker arms are torqued down to specs and that's it. There is no adjustment. If you have valve train noise you probably have worn valve train parts.
It means you are crazy or "nuts."
This vehicle is equipped with hydraulic valve lifters that do not require adjustment. They are set at zero lash by tightening the rocker arm nuts to 14-20 ft. lbs. If you hear a little valvetrain noise coming from your 3.1L engine, this is normal.
If its a OHV(Over Head Valve) motor, you can, if not, you cant. If it is a OHV engine, you have to use a five thousands feeler gauge, and adjust the nuts on top of the valves to tighten or loosen the clearance between the valve and the rocker arm, also to do this you must make sure that the motor is a TDC on the beginning of the Power stroke. Then slide the feeler gauge in between the rocker arm and the valve until you can barely slide the feeler gauge in between them. then tighten down the lock nut on the adjusting nut and put the valve cover back on.
Over reving the engine, ( to many RPM )The rocker arm nuts need replaced ( The locks are worn out on the nuts )The rocker arms are worn where they set on the valve stems.Need to check everything closely.
No valve lash adjustment,Unless you put in solid lifters.Otherwise tighten down to 25-35 lbs on the rocker arm nuts,they will self adj.
All of the brake pads on your 2000 Nissan will have adjustment nuts. You can turn the adjustment nuts to tighten or loosen the brake pads.
There probably "pressed in" so take a couple of old nuts or balls from the rocker arm, put the nuts on the shaft, then put the rocker nut on and just tighten it up, it willl pull the shaft out of the head. Good Luck
22 ft lbs torque on the rocker arm nuts is all that is required.
