Hello Armando, can you tell me how critical it is to run this oil line? Its my understanding that it pressurizes the upper barrel housing for lubrication of the pistons, and any blow by just goes through the injectors?.... It seems even though the rest of the pump is a fill up and run setup, that this is on there for a good reason. I also noticed that the RSR pump has screws to pull the barrels out, where as the road going pumps have pins pressed in.
