Depends on how much blowby you have. Mine went 1000 miles and had about 1.5" of oil in the tank. It comes with a valve you can twist to drain it. You can actually put a fitting on the bottom and hook a hose to it and run it to the turbo oil return fitting. As long as this hose is small, you can leave it open and it will auto-drain whenever you're not under boost.
i have a question about the crankcase vent itself. does it have any o-ring or rubber gromit where it goes into the block? do they go bad? its loose and i wasnt sure if there was some kinda seal there or if thats normal. i getting ready to install head and intakes and would like to address it before hand.

How goes it? Been having blow by issues. Vented the valve cover, O ringed dipstick tube and rtv'd the snot out of it. Still yet having oil blow out and its raking at my nerves. came across this system of yours and i had my father in law check it out. He mentioned that i would have moisture issues in the valve cover in the winter. Pretty much curious as to whether anyone has had an issue with this in regards to this setup
If you're referring to moisture if it's just sitting, I suppose any open system could have some condensation (though engines condensate with a closed system as well). It will burn off quickly when the engine comes up to temp.
Stinger have you or anyone ever tried the crankcase evacuation system that ties into the exhaust? We put it on our mini stock and it eliminated all blow-by and leaks. Just wondering if it would work on a turbo setup.
