This was a great topic to read!!! Just found it and read everything from beginning to end as this is exactly something I am currently looking at doing to my 2015 Sierra 6.2. Yesterday I pulled the TB and was surprised/disappointed at the amount of oil in my manifold. So I have a thought and I don't believe I saw this previously suggested but if it was then my apologies. Specifically about where to send the "filtered" air after the catch can. It seems there are basically two options. Venting to open, return to intake manifold or sending unfiltered air to the exhaust. So as long as the catch can is effective and filters the crankcase air why not have the "filtered air" dispense into your exhaust( after your last O2 sensor) using the nipples from the Moroso Crankcase Evac System #25900 that VdellaV introduced awhile back (thank you Vdella). Using those nipples and tapping into the exhaust pipe at an angle could create a "Venturi" like effect creating a vacuum on the catch can system assisting the removal of crankcase vapors and pressure. Now if the can does not catch nearly all of the oil than its not for me. I would not want this going to my mufflers or creating smoke. I'm sure there are potential issues this could create? Just a thought
