Anyone out there ever try using Rover aluminum valve covers on a Buick 215 ? I picked up a se and started shining them up, but last night I noticed that they won't seat down properly unless the baffles are removed and the little splash guard is removed from the Buick rocker shaft assembly. It seems to me that if I were to run it that way it would constantly suck oil through the PCV and the breather tube to the air cleaner.
