SOURCE: rocker arms

I believe you may have your terminology confused here. If I were to guess, you might be trying to adjust your valves to get rid of the valve lash/noisey lifters. If this is the case, you would bump your starter to bring number 1 piston to TDC on the compression stroke. With the engine in this position, you would then adjust various intake and exhaust valves using the procedure outlined in your service manual. I would hesitate to outline a step by step procedure here, as I fear you might damage your engine. Its not rocket science, but it sounds like you might need someone around with some actual experience. Once you actually watch someone do it, you'll be way farther down the road in terms of a good running engine as apposed to one that would be better suited to the scrap heap.....Let us know how it goes

SOURCE: how to adjust rocker arms on 05 chevy equinox

already ?
the standard procedure for adjusting rocker arms on some cars is to adjust them with the engine running. but this is messy.
loosen the nut until you hear clicking n tapping noise, stop.
now turn the nut Tighter a little at a time until you hear the noise stop, then turn the nut 1/4 turn more and move on to next rocker.

this only applies if you have pushrods.

SOURCE: need torque specifications for rocker arms on 3.1

  1. Install the pushrods in their original location, making sure they seat in the lifter sockets.
  2. Install the rocker arms and ball, then tighten the nuts to 14-20 ft. lbs. (19-27 Nm).

I Need The Pushrod Format For My 98 Chevy Venture.


The shorter pushrods go on the rocker arms that are closer to the intake side of the head, the longer ones go on the rocker arms closer to the exhaust side of the head. The camshaft is dead center in the engine, the further away from the cam the rocker arm is, the longer the pushrod needs to be.

I need the engine valve spec for a 1984 chevy 6.2 diesel. We are adjusting the valves.


VALVE ADJUSTMENTS All gasoline and diesel engines in this guide use hydraulic valve lifters, which require no periodic maintenance or adjustment. However, in the event of cylinder head removal or any operation that requires disturbing or removing the rocker arms, the rocker arms must be adjusted in order to position the pushrods to allow the hydraulic lifters to maintain zero lash. Refer to the valve lash adjustment procedure under Rocker Arms, earlier in this Section.
