[DeTomaso] Crankcase Ventilation. Catch can

[Kjetil Finne]

Chris

I was at first trying to only use breathers on my turbo engine, but I 
quickly found that this was leading to a lot off a mess.
I was building my own catch can from a stainless steel drinking bottle 
with a stainless steel pan scrub as a demister (oil mist/drop catcher) 
underneath the outlet opening.
This is working perfect as there are no oil in the air coming out off 
the can.

HOWEVER, I'm wondering if there is an actual benefit to using a PCV valve, or any of the other "mild" versions of smog control that is found on our older engines.

But I don't want to, and the only way I'll do it is if there's a really good reason to do so, a "better performance" reason. Right now I'm seriously contemplating installing a pair of valve cover vents, and that's it. Nothing else.

If they didn't have the air-oil separator, the intake plenum would accumulate a small oil slick over time... and extreme use.

They're straight thru to the crank case. Since this is an overhead cam engine, I have no lifter holes, or valley holes. My only drain back capacity are the four passages in each head.
