Does the stock oil separator on the PCV system not work well?

I'm sure it does, but nothing is 100%.

I can see how the breather hose on the cam cover gets oil in it. While in normal operation the flow is from intake to cam cover for PCV supply (They use the main filter instead of a separate unit), when you are at WOT there is essentially no vacuum differential and therefore no flow since the butterflies are wide open you get no pressure differential for the PCV system. So, when at WOT there will be blowby and some small amount of oil would travel UP the breather tube. When I was playing with V8's I used to see some oil in the cam cover filters, it was not much but it was there.

Sounds right to me.

There really needs to be a one way valve there too. Like I said, not completely efficent.

I was gonna put a oil catch can on my Focus and make a how to thread. Then I found out what hose I would have to get at. Too much work to get to that little hose on the inside of the intake manifold. I am really curious how well that stock oil separator works though.

This ^^^^

The sheer amount of work to access that hose is making me wait to see how the high mileage folks are doing before I even consider it.

I am in that "High Mileage" Club. My daily mileage has dropped significantly since I moved from Texas. But I have close to 38k miles on my Focus. So I am trying to see if I can get my hands on a borescope, maybe a fancy one that takes pictures so I can post them. I am curious to see what it looks like in there.

I always eliminate the PCV systems on my cars but I am not a tree hugger

Same here on anything I build the engine for, or an older vehicle. I just need to find the best system on this engine. I will probably keep PCV valve on this car I am sure, but probably use 2 breathers on valve cover and a separator/ catch can on th PCV side.
