There is no adjustment- the engine has hydraulic valve lifters.
They are fixed rockers so their are no adjustments for the rockers.
to adjust the rocker arms you have to either tighten or loosen the top bolt on the rocker arm/arms that need to be adjusted. there is a specified torque for the rocker arms that you should follow to help you adjust the them
A rocker arm shaft is normally a long shaft with rocker arms attached to it, that provides the pivet point for the rocker arms (newer Chevy motors).
The 1985 Chevrolet Corvette rocker arms will have an adjustment screw on top of each rocker arm. Turning the adjustment screw will change the height of the rocker arm.
There are no adjustments on a stock Pontiac valvetrain. You simply torque them to 20 ft lbs. Pontiac did not use locking rocker arm nuts. Any attempt to adjust them like you do a Chevy will result in the rocker nuts backing off.
The correct torque for the rocker arm bolt is 14 N·m (124 lb in) plus 30 degrees.
The 2000 Chevy Impala 3.4 liter engine rocker arm bolt torque specification is 45 pounds. The rocker arm bolts should be torqued in 15 pound intervals.
20 foot pounds
20-25 foot pounds.
There isn't a torque setting. You adjust the valves by tightening each rocker arm until there is no clatter and then tighten them 1/2 turn more.
For the 1989 Chevy S-10 with the 2.5 liter engine, the torque setting for the rocker arm bolt is 22 ft. lbs. The torque setting for the rocker arm cover is 75-inch lbs.
The stock rocker arm ratio for a Gen I Chevy small block is 1.5:1. The marine engines have the same rocker ratio, but use different cams and have bottom ends built to handle sustained RPMs.
Remove the valve cover. The rocker arm assembly can be removed by loosening the rocker arm screws. Each rocker arm will have a screw.
The torque specification for the rocker arm nut on a 1997 Chevy Cavalier is 22 foot pounds. This is the equivalent of 30 newton meters.
well, the 1994 is 25ft. lb's
19 - 21 ft/lbs
No you can get screw in studs mainly for high performance engines.
11 Ft/ Lbs + 30 Degrees
They are pressed in.
Lack of lubrication.
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
