i just recently got a 97 gt with a p1sc the car hasnt been tuned and they have the pcv system plumed into the blower intake tube and the car has alot of oil around the blower and the discharge tube as well as in the intake i was thinking that the blow by may be forcing the oil into the intake tube and sucking it through the engine and also the car runs like crap im sure with all the oil it has contaminated the mass air since its set up as blow through and possibly causing a miss at anything under 2500 rpms? i thought id get some of your opinions
