I have a 555 merlin block that has been sitting without oil for a while so I tried priming it and it took a good 15 minutes for it to pump up to the left side of the valve train (using a 1/2 inch good drill). The right side is still dry, is this common? I have 20/50 in it and the gauge is showing pressure now. Is it OK to start without oil coming up the right side valve train yet?
thanks
Scott
