Re: ------- catch can
Thats most likely their added value they call a drain hole. Which makes no sense why theyd send it with a fitting like that and you can even drain it thru the two tapped fittings on top. They stole a pic of a Real Greddy one, terds

Re: ------- catch can
Those pictures are fucked. For one, in the first pic, the blue line going from the valve cover to the turbo intake, the arrows are going the wrong way. For two, having a vented catchcan completely defeats the purpose of running the lines to the turbo intake....yer not getting any vacuum if the catchcan is vented. :P
Crankcase pressure is blow-by. Ideally all the BANG would stay in the cylinder, until the exhaust valve opens, but some leaks by the valve seals, and some leaks by the piston rings. The engine has two vents for blow-by.... one on the valve cover, one on the back of the engine, that little black box that leads to the PCV valve. Ideally you want vacuum in the crankcase, it helps the rings seal better.
People usually vent them for turbo setups. Little breather filter on the valve cover, vented catchcan for the PCV so you don't blow oil all over the engine bay. Under hard driving you will smell some gnarly blow-by fumes vented.
The better setup is to get vacuum on those vents...either from the turbo intake or a slashcut on the exhaust.

Re: ------- catch can
i made my own outta pvc and i hooked it up like in that diagram where there's a breather on the valve cover. my car started overheating after the catch can inctal so i threw the catch can away and just went back to the stock pcv system. i didn't have any overheating or any kind of problem since.
