I bought the doo oil cap for my 2013 just to be on the safe side. BUT when i put my motor back in my sled and went to bleed the pump i barely had any oil running out of the bleed orfice. I cracked the cap on the oil tank and all of a sudden i had alot more oil running out. It was definitely holding vacumn. Not sure just hiw small the vent is in these caps but it was holding back the oil flow quite a bit. Not sure if anyone has really checked it this way before but i am going to buy the passo cap with vent line so that there is no vacumn at all. I want to know my oil pump is getting unrestricted supply to it
