I’ve put about 1500 miles on my new motor. I had oil coming out the drive side valve cover from the 90 degree tube that isn’t hooked up to anything . This never happened on my old motor. I have a oil separator on the passenger side but nothing was hooked up on the driver side. The oil coming out of the driver side is that blow by or oil coming up from the camshaft? If so what’s ideal for the driver side having a breather or another oil separator?
