If you are worried about rolling over, put a tesla check valve into the line just above each diff and next to the tcase breather outlet, set up to let liquid in. Put another one in the engine bay that is the opposite way around, to keep liquid out.

No moving parts, gasses can flow as they need to but oil and water cannot pass the valves so they stay where they are supposed to be - and GL4 won't mix with GL5 either. Just make sure you get the right size valves so oil can't flow backwards through them, but air and steam can.

where on earth do you buy them from?

there's always this simple option

Haha all this info on how to run breathers, all this is because I couldn't work out that the axle has a cover inside that covers the hole. As. The sprung cover was seized and the hole full of mud and hung I will just run a hose up onto the bulkhead, maybe with a small filter, same as on the old SJ

That is probably the best option.
