I wouldn't be running a drain from the rocker cover to turbo drain. Any sort of pressure buildup in the turbo drain can lead to a seal failure in your turbo due to draining restriction. Since gravity is essentially the only thing draining the oil out of your turbo it is essential it remains clear. I'd be tapping into your sump, anywhere as high as possible, where the pressure/excess oil can be vented into your crankcase

guys i just got a gtr oil pump for my rb30 build and after reading this thread was wanting to know if leaving the 2 springs in the pump is ok as long as a breather system setup as duke57tt said will be ok? thanks
