Crank case ventilation setup

[deemo99]

If you buy the mini KV set that Matt sells, you can't go wrong. Matt sells only items that actually work and that he uses. Good enough for 8-sec, good enough for the rest of us.

I run the front KV only based on info from Matt. I don't use the car enough to warrant a catch can, but do have one waiting to install if I decide to. If you really want a 100% setup I have read front KV only and a catch can for each valve cover.

Front would be cover (barbed fitting) to catch can to KV to lower intake.
Rear would be cover to can to bubble (if you still use it).

My current can-less setup seems to be working and I don't have to worry about over-boosting the OEM PCV capability. PM Matt, he'll set you up.

Figured I'd throw out what I'm running PCV setup wise since its slightly different than most...

Barb fitting in front valve cover - no stock PCV
Small Krank Vent (to lower manifold)
Dual Adjustable PCV (have an idle and a cruise suck setting) with 3/8" barbs on both ends
Small Moroso Air/Oil Separator (t'd to each valve cover on pass side 3/8" - vacuum catch can)
Large Moroso Air/Oil Separator (t'd to each valve cover on driver side 1/2" - boost catch can)
*Used the Large Krank vent as replacement for clutch and brake booster check lines

If the single large can doesn't flow well enough I'll probably just add a 2nd large can and have two separate lines off the valve covers, and also add a breather line to the front pre turbo pipe. If the flow changes at all due two having two breathers vs just one, adjusting the PCV will fix it and help keep that airflow to the lower intake manifold consistent.

There is a pretty good discussion about this on the first few pages of my build thread as well.

I ended up putting the oem pcv back in, but also keeping the front KV as well since it will hold more boost. I was smoking at start up and under vacuum while driving. Wife could tell every time I used the clutch following me home from work. The start up oil smoke was gone within 4 startups. After doing 120K and having some oil puff at start up I was really getting nervous. Glad it was simple and free this time!
