ever since i put my lsvtak together i've had issues with smoking... well i finally tracked down the problem. turns out it was a line i was using for my catch can that was leaking oil onto the exhuast manifold making me smoke under acceleration, in vtec and only when warmed up. so, now i've devissed a new better catch can breather system... but need some info/insight on if its good nuff... basically i will be venting via the valve cover as well as two nipples on the back of the block. I want to know if i should just freely drain into the oil pan or should i have a valve in the way of the drain? see diagram.
