Great thread. Best thing to do is just get a VVL valve cover to get rid of the oil catch can.

EDIT: vumno already said this, haha

This is brilliant as usual Ben. Much needed, compiled information. Can't wait for the turbo section as I was literally just discussing different options last night.

If you eliminate the full throtle part of the pcv system a vaccum leak created at idle and while on vac. by the unmeasured air of the part of the vave cover that goes conected to the intake duct before the MAF...

Hey Payu, you mind trimming down that quote to something smaller and more to the point?

You're right about the unmetered air. I feel like that's one part of the system I haven't explained well at all. I'll make sure to do that.

Since you asked and I don't have that example up yet...
It's a bad idea. It's exactly the same as doing the breather filter on an older DE. Same deal really. Same pros and cons. I'm not going to tell someone not to do it, I'm just trying to give people all the facts so they can decide for themselves if it's worth it to them to modify the system in certain ways.

Since you won't I will. And I appreciate this post with great info and awesome pictures.

Unless you are an engineer and this is your daily driver, stop playing with it!!!

If you are racing, do whatever you want!
