How to vent your valve cover

[speedminded]

could you just run it back through a pcv and through the intake back in the motor like it is oem? I always thought just releasing all that pressure would do more harm than good...of course there are extreme cases..but..u know!

You don't want that sludge from the block to go into your intake where it's sucked in coating the injectors, spark plugs, gunking up the valves, and top of the piston where it's just going to burn anyways. A catch can allows the crankcase to vent while preventing the sludge from being recycled and burned.

Dragsters have been known to run vacuum pumps from the PCV system freeing up to 50hp...but I think the NHRA banned it lol!

so basically i have a jdm b16a 2nd gen but am hooked up obd-2b so i don't have to worry about all this do i, i remember everyone putting the little filter on the valve cover but that wont hel me. my hose runs from the VC to the intake so i guess im good. this will make me rethink a b20 bottom end on my car. also would venting my block be a good idea and very costly, i'm ballin on a budget til the ball joints are done and CV axle.

You'll get very little, if any, bloy by from the valve cover. I've always run my block through a catch can and the valve cover to the intake and my intake manifold was always spotless.
