Here's Hal's billet oil cap, and -10 line to a catch can.

Seems excessive. Why not just weld an bungs onto the side of the cover?
 
Interesting concept, would love to see some tests done.
 
Is the stock VC breather port just left open as shown in the 2nd pic, or do you have it running to somewhere?

Is the PCV valve bypassed? Can't really tell from the pics.

Yeah, the PCV is bypassed. I am pulling the breather barb out, tapping for 1/8" NPT and running an additional -4 line to the catch can. Its just not done yet.
 
Looks great J.P.! It won't be long and I should have this setup on mine as well. :thumb:

I'll be home in another week so I can start pulling off the old intercooler and intake manifold! Thanks for the billet catch can BTW. I have to install that as well with all the other parts that are laying around.

The vacuum source from the intake is an interesting idea. Any other thoughts on this?
 
I could use the intake as a vacuum source, but I have been floating the idea of using the exhaust instead. Next up, will be using a -4 line to drain the catch can back to the block.

I wouldn't. That catch can catches water vapor and gas vapor along with the oil. It cools and condenses in the catch can. Do you really want to put that back into your oil?

The stock setup puts it back into the intake so that it eventually goes out the exhaust instead. Eventually...
 
is it safe to vent to the atmosphere with the stock maf? Wont that cause unmetered air to enter and exit?

He has the PCV valve bypasses, so no unmetered air is getting into the motor, nor is any metered air getting out. This system is essentially opens up the ports to allow the crankcase pressure to exit less restricted.
