I'm building a B20vtec motor and I'm kind of worried about crankcase pressure. I'm planning to tap into one of the plugs on the block Endyne style. From there, to a inline catch can, then to the PCV valve. All enclosed system without venting to the atmosphere.

Would one plug on the back of the block be enough to relieve the pressure of a 11.5:1 compression motor revving to mid 8000 rpms? Or should I add another plug and redo my system?

 

yeah that would work

 

Cool. So no need for dual plugs like Endyne's catch can uses?

 

i drilled out my oil fill cap, and put the pcv valve in the cap on my old ls/vtec setup.
the b20/ls motors have the pcv valves on the valve cover anyway. worked fine for me.

 

Right on. Thanks.
