So ive spent too much money testing out PCV setups for my d16y8.

There are tons of setups for B series engines...but only 1 main one for D-series.

The setup is

OEM setup, with a catch can between the Black box and IM....on the Catch can, a check valve on the drain ****, which allows the PCV system to breath @ RPMs from 4k+ or WOT.

Ive done alot of research and it shows the PCV system sucks at any high rpms, because there is no vaccuum at high rpms and high load.

This system will still allow gasses to be "pushed" out of the catch can, into a small container. So its pretty much an open system, but for NA.


also i want to get rid of the actual PCV valve, but when i remove it from the system, there is a HUGE vacuum leak....which i dont understand because the PCV valve is open @idle. Is it allowing to much air in? The PCV valve is a huge restriction on the setup, and doesnt allow for very efficient evac of gasses....

also is there anyway to get rid of the EVAP system? dont care about emissions, just want the best reliability.
