Exhaust crankcase breather set-up - Scrapyard hunt?

Here's a pic of the OE system if it's any use.

I expect it'll have to be quite small to draw a decent vacuum.

Smaller would equal more restriction (when it was flowing), not more vacuum.

The theory is that the exhaust flow passing that pipe creates a vacuum that will pull the crankcase gasses out (through a catch can)

Are you aware of anyone else using this design? Exhausts aren't an obvious source of depression, especially under power.

David Visard did some research on this, it was usually used on his dragster engines as you run full throttle and high exhaust gas speeds.
I would think you would need a heat proof Non return in the evac pipe

Yeah, that was the reason for the thread, trying to find one suitable in the UK to save me buying one in the US

My search in the scrappy turned up nothing of use. I did manage to find a UK company selling one which is good although I still need a one way valve
