Ok, i did search through the archives on this subject. But not many deal with a block that has no black box. So im trying to figure out how to set up my oil catchcan without having the black box. Im running a b20vtec so there isnt one available. I already put the two honda fittings into the back of the block where the hex plugs were and now im just trying to figure out plubming. My oil catchcan is like the old greddy one



so there is not breather. I normally see people attach this style catchcan from black box to the catchcan, and then to the intake manifold.

I was thinking that i should tee hoses to the 2 fittings to the block into the catchcan, and then have the other side lead to a vacum source the intake side of the turbo. wouldnt intake be a bad spot to try to vent it since when you hit boost it will basically freeze up the system?

Borrowed from an archived post



Any other suggestions? oh yea, and what about the valve cover? should i tee that in as well or just put a breather on it?
