Doug said that there is no other place to locate the valve on the Cleveland except into the valve cover.
It seems like the air movement through the system would tend to help drain oil out of the breather fitted valve cover and tend to help hold oil within the PCV fitted cover, netting one generally empty rocker cover and one usually full cover.
Does the PCV system really pull enough vacuum make this happen?
Would there be any advantage to mounting the PCV valve through an intake manifold down onto the lifter valley? Seems like it might help to pull oil out of both heads more evenly, if the effect is truly that strong.
Winter ramblings, below zero again this morning.
