Sump baffle, check valves?

[Error404]

Yeah just been out to the garage - the 7A one mounts lower in the sump, so combination of both plastic tray and windage tray should be an enhancement i guess. Have 7A sumps just gone up in value?

I'm trying to make the standard sump on my car a bit better but cannot find what i'm looking for.

They are small rubber flaps thet pop into place to let oil flow in one direction.

I know people use them in cosworth circles like this.

Anyone know where i can buy the rubber flaps from

Where i used to work we used to make up windage trays and sump baffles for rally engines-back in the days before digi cameras so no pics unfortunately- but it involved a LOT of measuring and trial & error- the best/easiest/cheapest way is to make up trap doors which allow the oil flow TO the pick up pipe but stop it flowing away from it.

Quick sketch-up of sump sidewalls with filter in.

Just the idea of sandwiching the foam between two layers of aluminium sheet looks like this would drain the oil nicely, and keep it down.
Next best thing would be to add some baffles inside the lower part of the sump.

I decided to make my own baffles and check flaps.






I should be going dry sump next year but this should help for now.
