I NEED TO VENT!, (my crankcase) Options

[airsix]

I've been procrastinating away the winter, but it's time to address a few items before spring.

Oil leaks - Ok, this is my biggest problem and is the reason for this post. I'm getting a lot of crankcase pressure since I added the turbo. Off boost I've got no oil leaks. On-boost I've got leaks from the valve covers and pushrod tubes (both new and in good condition). I've got the rocker-box vents plumbed up to the spark-arestor where they are joined by the oil-filler vent hose and this three-into-one arangement then goes via single 5/8" hose to a home-made catch can. Do you think running these as three individual lines (rather than plumbing them down to a single 5/8" hose) would cure the problem, or do I need something more agressive in the way of venting/scavenging?

Yep,

One to each head, and one to the filler cap vent...its even mounted almost exactly where yours is mounted. After a good spirited run where the revs are over 4K for any kind of period, or a few autox passes the element on the inside of the box will be fairly saturated and there will be drips under the box on top of the engine. I have also had some problems with oil seeping from different areas on the engine and I think its because the crank case can't breath well enough...and thats also what Jake suggested, so gonna follow the builders advice and put a bigger breather on it...I built a box almost exactly like Chris's shown above...
