Interesting aftermarket PCV - ZR-1 Net Registry Forums

Good find. I remember looking at that 10 years ago. If one wants to run pcv I think that is a compelling option. I never pursued it because I vented to atmosphere , but I was considering this one.

The two things that jumped out at me were:
The dual mode function of this unit which resembles the LT-5 dual but different valve set-up.
The tunability of both modes which would seem to lend itself well to modified and big cube LT-5's which are likely creating crankcase pressures outside of the original design parameters.

My thought would be to run 2 lines from the stock IH venting locations directly into a oil catch can and then mount this adjustable PCV above the can with a line running to the stock plenum fitting for vacuum. I think it could be a pretty clean install and unclutter the mess at the rear of the plenum a bit.
