Venturi vacuum pump

Here's what I think would be the best "simple" way to install this. One might even go as far as adding a catch tank between the breather and exhaust check valve so as to keep oil out of the exhaust if possible. I also don't know how well the drain tube from the catch can to oil pan would work, but my stock oil catch can does that so I think it would work.

Wouldn't you want a catch can in between the vent and the intake?

Well, the PCV goes to the intake normally, so that's why it's going there now, and in all of the KV setups I've seen, that is how it's done. I suppose you could hook up both ports on the valve cover to the catch can and only one vacuum source, but either way, it's good to have two different source for vacuum, if possible.

Anyway, as long as there is a vacuum, both the pcv and vent will see that vacuum, doesn't really matter where you get it, as long as there's a check valve.
