ok this is the issue im having....the pcv nipple on the back of the genv is creating a suction.....the nipple on the l67 tb is also creating a suction....
ive seen write ups that say connect the one on the genv to the tb to fix it and block off the evap connection on the blower, mine is jb'd shut.
i had no idea pcv wasnt functional until i heard a loud whistling when driving and when i tried to pop off the oil cap it had a suction (at this time both nipples were vac capped.) when i remove the genv cap and leave the tb capped i get no oilcap suction or loud whistling/squealing. here are pics below about what im talking about.....could the pcv just be bad? weird thing is i drove with both capped for awhile with no squealing or whistling but i just fixed a leaky front valve cover today and the gasket was bad so maybe it was escaping there and preventing whistle....pcv has free play when shook and the plastic shaftgoes in then pcv valve then spring and cap.....cant figure it out.
