Aluminum Dry Sump Tank Questions Options

[gnomefabtech]

Hello All. I'm using one of Ben's aluminum dry sump tanks and am having some issues with the motor "wet-sumping" and flooding out my turbo.

I have a cracking valve in the oil return hose and I'm pretty sure the oil isn't coming in that way, but I'm wondering if it can come in through the scavenge side instead. I don't have a check valve in there because I assumed (yeah I know what happens when you assume) that the outlet was above the oil level and there would be no way for it to return that way.

Is all I need a check valve on the scavenge line? Does Porsche have one there on it's stock dry-sump setup? I'm not running a Porsche engine but it is a dry sump.

Thanks.

Thanks for the tip. There are a few options that have the anti-drain back valve. On it.

I have a low cracking pressure valve already in the oil feed line and it does stop the drainback on that hose. But I now realize that the filter had no valve so the oil was just coming in through the out door.

Thanks for the ideas.

I will post some pics and videos of the car too. It's a bit mental with an 11k RPM 300 WHP motor in there. Separate thread!
