hey guys need a little help please! sice my cam swap ive been having low oil presssure once the car warmed up, around 20psi @idle. ive changed the oil pump did not work, even took it off againg to make sure it wasnt the o-ring on pick up tube.it was fine. i was looking at my injectors and notice the plastic ring on the tip was broken in half. could this be causing low oil pressure???
