I have a midliner engine (Renault) i recently broke a valve,It did not drop into piston,but I swapped the head out,actually replaced all head gaskets and orings.now I notice the head I swapped out has no oil pumping up from below,probably the reason for the valve problem,any suggestions on remedys I could try to get the oil up.the other clyinders are pumping strong. thanks
