new OCC design i cam up with, solves both crankcase and VC pcv's under vac the crankcase blowby and the VC pressure is circulated threw my baffled OCC, then the filtered air is forced back into the inlet tube to prevent any loss of metered air that blew by the rings, ect... and the best part is under full boost the IM check valve closes (to prevent boost leak) and then the positive crank case and VC pressure r sucked threw the OCC, filtered and run threw another check valve (that closes under vac) back into the intake so that no Metered air is lost and all the hp killing positive pressure that puts resistance on the pistons is instantly sucked out by the turbo inlets vacuum and filtered, and recirculated, like stock but way way better, plus this design i came up with is the only one where u dont need two different OCC's for the crank case pressure and another one for the valve cover pressure. Lemme know what you think.
uuhh... if you want the top valve cover blow by port to flow threw the catch can while in boost you must route it to the lower crankcase PCV hose!! because if not the OCC is worthless hooked up the way that Bombermanx has his hooked up because it will only filter blowby threw the OCC durring normal driving or vacuum, but as soon as he hits boost his OCC is blocked off by a check valve to prevent a boost leak and does nothing at all!!! and then while in boost his crankcase blow by (which is even worse while in boost) is forced out of the top VC port pumping dirt, oil, fuel and contaminated air right into his intake! so basically he has no OCC when he needs it most, under boost!!! with my design the OCC works under all conditions idle, cruising and WOT! by connecting the top VC port to the lower PCV hose between the blocks PCV and the OCC is perfectly fine cause they r both coming from the same source, and with my design you completely eliminate oil, fuel, dirt ect from going back into your motor not just threw the intake manifold but also threw the intake!!! It works perfect ive already done it and the car runs better than its ever have!!!!
