Default Crankcase venting

I know it's been beat to death but I got a question. What about using 2, 10 AN fittings like they put on oil pan for the turbo drain on each valve cover? I was thinking of bolting 1 on each valve cover, 10 hose on 1 to a catch can with breather, and the other to a 1 way valve in the down pipe. Why wouldn't that work?

That would work fine but why not but weld them instead of bolting them?

****, I almost missed it. There they are. I don't typically pick up on much gay ****. Must be a life style choice. Understandable though, guys with ls swapped Nissans and ****.

So, do you guys see many set-ups running a vacuum pump like the Lightning ones?

One thing that no one has mentioned is the need for a 45* angle on the bung.

i personally don't find there is anything to gain putting around on the street with a vac pump spinning unless your pockets are too heavy.

if you do have one you should really have a regulator so you can crank it up at the track and crank it out for normal driving.

Question for you guys that run the PCV to the downpipe... Is there any rule that you should or should not run a wideband O2 downstream of where the pcv line attaches? Is there any reason that the PCV attachment would effect O2 readings? Just something I was thinking about.

Not a good idea. Blow-by mixed with oil in the exhaust stream...

you could also run a catch can in-line of an exhaust 'road draft' to help

that is of course once you made sure that method suits your needs.
