PCV necessary on boosted apps? I was thinking about running dual breathers on both valve covers which would delete the pcv system.
Question, what pro's and con's in doing that?

) inline to intake to catch the oil. Last edited by Vcious04; Sep 2, 2009 at 11:13 AM.
So far so good with both rocker covers vented in to my home depot catch can, I've made at least 200- 6,500 shifts with this set up with out the seals coming out of the engine. 
... I about had a heart attack when my seal pushed out on the dyno at 5,000 rpms. I thought my brand new forged moter **** the bed.

I will be venting mine exactly like you have yours as our combos will be very similar.
The forced induction world is one of the biggest love / hate relationships I have ever had in my life.
The intent of the PCV system is to reduce crankcase pressure manifested from blow-by during the engine cycle. Engine vacuum is much more efficient at drawing these gases out of the crankcase than venting to atmosphere. This also creates a small vacuum on the crankcase that does slightly improve ring seal and power output. The final benefit is the environment. A closed PCV system recirculates the blow-by gases rather than releasing them in the atmosphere.
Thanks for the pics, is there anything in the catch can? And why no way to drain it? Just planning to take it out and pull the lid off? Looks good and like a good idea though!
I have these oil absorbent mats I use in my shop that I cut and pack into the bottom. The top of my can unscrews and I just change the mat when its oil soaked.
Seems like a good idea, I know the mats you are talking about .. Seems a lot simpler than other peoples setups I wonder why so many people do really complicated setups?
I don't see much oil in my can. Not like I've seen other guys on here. A piece of the oil mat 4'' wide and 12'' long rolled up like carpet jamed down in the bottom will last 3k miles no problem in my car.
