im jumping into the turbo world. im trying to figure our how to l add a pcv on a twin turbo lq4. i want to use early Chevy script valve covers that have no provisions for pcv or adding oil. is there a way to do the pcv with out making a hole in the valve covers? or is there a way to hide the pcv? if i have to make a hole. can i just use a fllter and vent out to by its self or do i need a catch can?
i hope that makes sense.
thanks in advance

 

Good question.

 

yeah I just wish someone would chime in. I know I can't be the only person who thought of this.

 

Positive Crankcase Ventilation is the bottom line so anywhere that's not under oil would work I would think.

 

Not sure why you want to run PCV on a turbo build. Most builds I've seen ventilate the crankcase using the valve covers or valley cover and a breather tank.

 

so i can use a ls6 valley cover to vent the motor? do i need to use a catch can or can i just vent both valve covers to atmosphere?

 

I would just weld 10AN bungs on each valve cover and vent them to atmosphere.
