Rocker arms???.... Might need a Schjeldahl for this one.

[Anonymous]

Im at the point where Im ready for rocker arms on my head swap.

1. Are all the rocker arm bolts the same? What about the washers?

2. I did not label the pushrods when I took them out. Is this a problem?

3. If I go with adjustable rocker arms how do I adjust them? I came across the directions on this site a year or so ago, but cant find them now.


Thanks alot!

The bolts are all the same. If the washers look identical, they are. If you have one with a secondary bleeder hole to one side, this goes to the rear. Pushrods mate to the surface they are familiar to. In extremely worn motors, this can cause some binding if mis-matched. I suggest that if you have lost the positions, reassemble with assembly lube on each end of each rocker, and run them slightly loose for ten minutes.

As to adjusting the rocker arms, it is basically a matter of having the lifter on the cam lobe base circle for any given valve, and adjusting the rocker until you just feel the slightest drag when spinning the pushrod between your fingers. Then tighten it a whole turn only.

Howdy back Spyke and Adam:

Adam has cover your questions very well Spyke.

Look over the ball ends of the pushrods very carefully. If you see anything other than a nice round shiny surface, consider replacing that pushrod. Damage to pushrods is usually due to lack of oil getting to it. So before you reassemble the rocker arm assembly, thoroughly clean and rod all oil passages. Don't miss the hole on the rocker arm, on the top, at about the 11:00 o'clock position on the valve side of the rocker.

Upon start up, do it with the valve cover off and watch for oil to seep to the front rocker. If you don't have a good supply of oil to the front rocker within 5 minutes, something is wrong. Stop the engine and find the oil blockage.

If you go with adjustible rockers you will need the appropriate ball and cup pushrods.

Adios, David

Just to add to David's comments, save yourself a little more aggravation and pre-lube your engine. You can use a drill to power a socket or run it by hand with a speed wrench. I've used both methods, and they work fine. Just a wee bit more comfortable to not have to worry about oiling with everything else on start up.

as czln6 said you will need different pushrods all together. so where the old ones came out does not matter. as far as oiling i used an old dist. shaft and rod.put the electric impact wrench on and went to spinning the oil pump...frank...
