That will only work when that pump has enough capacity to create a vacuum even with the manifold under pressure. I don't think it can. Vacuum pumps for crank cases are available, but tend to be a lot bigger than that small camshaft driven pump.
But why not use the oil return hole in the engine originally meant for the turbo oil return? Put a pipe on there like an oil dip pipe and a filter on the end, essentially just opening the crank case to atmosphere. Close the PCV system. Vent the head through the cam cover using that fancy catch tank. Or did you already cover that in one of your iterations?

I did consider the oil return at one point but decided against it,

Carve some big vents in the rear of the clam😂Was thinKing of modifying the mesh as it a other place to let the heat out

Know the feeling. You should try shelling out for an oil cooler and fittings at the same time!Well I sh!t myself today And not because of the HARROP £300.00 spent on bits and fuel pipe to alter the fuel lines down other side of the engine Wow I'm gob smacked It did include bits for fuel rail Jic/unf hose fittings 200 series fuel hose

We need updates in your build graham
When I'm in the mood, and have some decent daylight pics.
Hoping the next time I update it'll have been dyno'd and can do a proper positive catch-up on the project thread.

I was not after creating a vacuum within the engine Martin, More of a case of using a suction to remove any crank gasses I solved one problem at a time. 1. Oil within intake & laminovas 2. Creating vacuum/suction to remove gasses 3. Give the engine fresh clean air 1 + 2 were solved easily by using brake vacuum pump No connection to inlet And suction from vacuum 3. was the biggest issue which would not work with a airfilter with the continuous suction from pump would simply not allow filtered air in to engine through the cam cover exit, I also think this would be the case even when the cam cover pipe would be connected to inlet between TB and the filter as there seen to be suction all the time from there Thoughts are appreciated MartinUnless the vacume pump has the power of a vacume cleaner there is no way you will create a vacume with an open to air filter on the rocker cover! Go back to your earlier design the way the system was ment to work. I really liked the design with the catch tank bypass.

You could even use the Noble one.
