The tall cylinder mounted to the dry sump tank is the transmission expansion tank. I run the vent line off the trans to the bottom of that tank. During open track days I have seen the transmission push out fluid when it is hot. Makes a mess. So now we add an expansion tank. Fluid get hot gets pushed into tank then drains back into trans when it cools.

I have to admit I've been lurking about looking to replicate this oiling/venting system. I think Donny was questioning this before, maybe on a different build, but I'm wondering how to route the oil return from the air/oil separator. Above or below the oil level? check valve? No check valve? Vent it to atmosphere?
