ME/ Wagner PCV

MopaR&D said
So with the breather-less setup is the crankcase pressure at WOT able to push through the PCV even though there's barely any vacuum on it? Seems like that would be a restriction which would cause more pressure buildup and oil leaks if the engine is run at WOT a lot...?

I don’t know about that, because I also ran a pan evac system. At idle the PCV does the majority of the work. At a cruise, you have both systems pulling crankcase vacuum and at WOT the pan evacs carry the load.
