Whats the proper way to vent the crankcase on a turbo lq4 6.0? There is a pcv valve and hard line in the drivers side valve cover... and the vent tube behind the throttle body leading to the passenger side valve cover. Do you plug them off? use some type of check valve? I plugged off the pcv and have yet to remove the thottle body/passenger cover line and everytime it gets in the boost... it makes for a nasty smoke show! Thanks for any help! I hunted all over town today for a 3/8's sized one way check valve but found nothing...
