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.

First off. The depth of knowledge here is really amazing. Thanks.

I'm running a turbo Suzuki Hayabusa with a dry sump. The turbo is lower than I would like, but it's still higher than the flat pan by about 4 inches. No smoke or problems when it's running, just after a few days parked.

So when I looked up the oil filters that fit on my tank, they don't specify anti drainback valve. I'm not sure that Porsche ever thought it needed one. Do you have a part number for one that does have an ADBV?

Last question, the filter stud is 1"-16 I seem to remember. Is that right?

Oc54 is the Mahle filter but they no longer function properly in my opinion. Buy the MANN equivalent

Rothsport does have a check valve or something like this will help. https://www.improvedracing.com/high-flow-fl...e-4an-male.html
