Id sure like to see someone post pics and a diagram of the following:
A pcv system that works well under boost, has no oil mist from breathers on the valve covers, a nice looking setup. Those three things together i would like to see.

I was made an offer I cant refuse. A Sponsor says they think they have the solution. I just have to make the hour drive from my house and let them do it. Nothing like free if it works

That's why you put in a check valve so the flow only can go from the valve covers back in and not the other way.

That is true but then you still risk getting oil mist/fumes into the intake. I did this for about a day and it stopped the little smoke I had at idle but I didnt' want to risk getting oil in the intake so I blocked it off completly.

The ford guys are using a catch can as well, but they run one line each from both valve covers into the catch can and then the other line is attached to the turbo inlet pipe to create a vacuum.

Talking pvc catch can set ups look at urls

i just had my first hard run.it boosted double the 6lb. spring rating with the WG's not yet plumed for control.
i oiled up the windshield a bit from the breather(no hood).i tread 12lbs for a second and backed off.latter we checked the HPT log and we figured a 15 # boost had occurred.
i started it up latter and all checked out,pressure,fluids,levels.all seems good.hope nothing broke

That's how I have mine ran. Original lines from both vc's, and another line from zo6 valley cover, to catch can to blower inlet. I recently had my blower hat off and noticed some oil in there. I have a breather on the pass. vc as well just to be safe as I am nervouse about pressurizing the cranckcase. Even tho I don't have a lot of miles on this setup I need to check my catch can to see how much is in there.
