Currently have a lot of crankcase pressure pushing oil out seals and what not. My current system is just a line from each valve cover going to a dual inlet catch can from allstar(http://www.amsperformance.com/cart/A...mance.com.html). Just wanted to see what people thought about doing something like the picture below. This is on a Turbocharged 383

I don't like dumping that crap back into any engine. Especially not a N2O or boosted one.
I don't want any contamination in my charge. I'm not a turbo expert,
but it might be worth a vacuum pump. If it's too much, at least try an evac kit.
Check jegs or summit and you can get some ideas & pricing.

Thats why I would using a breather/seperator tank to seperate the air from the oil so the oil wouldn't go back into the engine. My thinking could be incorrect though.

I also am thinking about using a lt1 electric smog pump hooking the inlet of the pump to the valve cover

I am having some of the same issues with too much crankcase pressure. Does venting the valve covers help with crankcase pressure? How do the gases get up there, through oil passages? Is there a better way to vent the block?

Yes, if you put a breather/filter on the valve cover ports or an oil fill cap breather/filter you will eliminate any crankcase pressure from building up anymore. The crankcase gases flow right up into the valve covers.

But you should still pull crankcase gases/moisture out somehow. External vaccum pump venting to the atmosphere....or using a catch can and the normal vaccum port on the intake.
