Description

Predator 212 , gx200 ,  gx390, Briggs  animal
Block / cylinder head.      PCV valve
This is a PCV valve that’s installed “in line” on your vent tube.
This uses a 3/8” vent tube
( a 1/4” vent tube does have enough cfm capability to keep up with the air volume created by the piston)
Just install “in line” on your block or cylinder head to install
This valve creates a vacuum inside the block that seals the rings better . Without a proper PCV valve the block and head venting is pointless or just for show . This vent allows air out but not back in creating the vacuum in the block and head that seats the piston rings, valves , and keeps oil from being blown out crank seals and valve covers. This valve also makes fuel pumps more effective at pumping fuel is pulse pump Is powered off the block or head vacuum . Will not effect pumps powered off the intake.
