Decided to pull intake and reseal because of small oil leak in the rear of the manifold. To my surprise I found a broken pushrod. The break was where it went through the head so both pieces stayed in place enough to still open the valve. Motor never had even the slightest miss. Anyway the Comp replacement rods have oil holes and the ones currently in the motor do not have oil holes. How are the rocker arm assemblies lubricated without oil holes in the pushrods? Which way do I proceed? Oil holes or not???? Thanks. 1973 340 Cuda.
