Dry sump leakdown prevention? Options

[gnomefabtech]

Hello!

So I'm running a dry-sump system on my 'teen and it's all great except if the car sits for a few days the oil in the tank slowly fills the motor. This wouldn't be a big deal except it floods the turbo and then there's smoke. So much smoke.

Does anyone have experience using a low cracking pressure check valve to hold the oil in the tank until the car is running? I see a selection of these on McMaster but I'm understandably nervous about restricting the flow into the engine from the tank. It's a -12 an line coming out of the tank. What did Porsche do about this on their dry-sump systems?

I'm running a Hayabusa engine (build thread to follow) so it's a pretty unconventional build but the oiling thing is common to all dry-sumps.

Thanks for answering these questions.

Rothsport. Is your engine worth more than $300?? Mine is on a factory -6, there are 911 versions also. This is NOT your run of the mill 'check valve'. Too little sealing pressure and you might as well not bother; too much and you get oil starvation on startup followed shortly by spun bearings.
Some things in life you can go cheap on; this isn't one of them.
