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. |

Edit:
I have dry sump in my /4 race car. I put a manual valve in the tank line, that I turn off after each session and clip my master switch key to it as a reminder. There are drainback valves for the 911s; Rothsport and Willhoit come to mind. |
