diff breathers
Hi once again everybody. Another question for you all. Do the diffs and/or gearbox run at a positive pressure? ie. are the breather valves "2 way" .. and at what pressure does the breather open if they are

Just hoses that are run standard as to a cross member for the rear and to the left front guard for the front.
They act as a snorkel so that when a hot gearbox or diff hits cold water it sucks in air not water.

G’day Timbo mate!
To the best of my nuffy knowledge it’s a free venting system up as safely high possible:-)
Not too firewall high though as you’ll snap the diffusers off the Mrs truck when closing the bonnet :-)

I actually have the inlets on the firewall mounted pointing down so that no water can enter either from deep water, rain or spray washing the engine bay.

Top idea Craigstar mate, can’t argue with physics good man!
Her truck stays somewhat above water, unless dam ghosty run time for a Y62 wanting so hopefully just dust prevention for us

I thought there was some internal pressure as their is a spring in the valve itself. Thought it might have to do with keeping a positive pressure to help keep out water via the seals .. but if that's the case and it's free flowing then all is well :-)
