ok so i've read quite a few threads on them both and i'm still a lil confused lol. i'm gonna be running the endyn crankcase breather kit out of the back of the block, now heres my question........if i'm running that, do i really need to vent the valve cover with catch can also?

i dont wanna waste the money on gettin the AN fittings and bungs, plus catch can if i dont really need to run it also. i was gonna run a small UNI filter on the valve cover where the outlet is near the oil cap, any reason to not do that?

oh and if it makes a difference, heres the setup i'll be running........sleeved ls/vtec, 12:1 comp, 85mm bore, twm itbs, rmf compact header, ported head with buddy club 4's


thanx for any and all help!

 

the only way to really know is to put a boost gauge on the engine and see if the crankcase builds positive pressure are higher RPM. you might be able to find a pressure gauge with a small sweep also.

you should be able to temporarily do it off the valvecover nipple. if the boost gauge uses a small plastic line put the 1.8npt fitting on the line and stick it into the hose you have connected to your valvecover
