<font size="2" face="Verdana, Arial">Close, but our PCV system runs from the front of the block under the header to the back/bottom of the intake manifold and does pull a vacume on the crankcase.Originally posted by zx3 focus racer:
yes carnk case vacuum helps the rings seal. but our pcv is before the T/B. vacuum is only created after the T/B. our pcv is there for emisions. the vapours from the crank case do into the intake and then out the exhaust after being burnt and goin through the cat.
