Knowing that an E-vac system is great for drag cars,is this something that would or would not be recomended for a streeet driven car?As when you're just cruising it around are you slowly filling up the exhasut will oil residue? This is on my car and is the way I bought it,and after a few full throttle runs,notice a cloud of oil smoke behind the car as I stay on it.The car does'nt appear to be "using up"oil,so just wondering some input from you guys on this topic,and is something I should remove?
