Rocker arm, pivot wear


tanny

Recommended Posts

I was adjusting the valves on on my 73 240 and noticed that the rocker arm pivots have a large variation in their height in relation to the head, causing the angle of the rocker arms to vary significantly with respect to the cam lobes(I assume due to wear). All were adjusted successfully, but a couple of the valves were getting close to the point where I will not be able to adjust them(not enough room for two wrenches) if there is much more wear on pivot and/or rocker arm. The head just received a valve job and all springs replaced. Is it necessary to replace the rocker arm or the pivot or both? Which part usually wears out first(lash pads, cam lobes, and rocker arm wipe surfaces look fine)? Thanks, Victor.
