I have tried to search this issue, but I'm either a computer spastic, or asking a new question...
Regarding diff breathers, and the transmission, fuel tank etc...
Is it ok to run the plumbing into the snorkel? IE it would have a much higher port leaving more room for river crossings etc.
My thoughts are that it may have two problems, one - rain or moisture from the intake air, two - the venturi effect, run higher pressure air over an opening and the air in the opening, being lower pressure, gets sucked out, would this intake air be moving fast enough (remember turbo!) to pull the oils up and possibly out?
Thoughts??

Mods so far - EGT & Boost Gauges in Pillar Pod, NADS, upgraded inter-cooler, 2 in suspension lift, 33 in tyres, steel bullbar, spot lights.
Furthermore, I have seen the mathematical formulas for measuring the pressure, but don't have the tools to figure out the flow rate in the snorkel at the point of entry for the breathers... I understand the boost gauge may give an idea, but I think the actual flow rate at point of entry is what I'd need, over the whole rev range... phew...

Most diff breathers are run to the firewall in the engine bay.
I wouldn't be drilling holes in my snorkel to accommodate
any air lines. I used 6mm Teflon tubing with the quick connect fitting making sure it won't foul
on exhaust or other fittings at full stretch, terminating at a manifold with Air filter mufflers

the Engine bay should be fine mate, the suction effect during a water crossing will occur as it cools rapidly, this will be over fast and then it should not really be an issue. THe idea also is that if you do the river crossing with a crossing bra then the bow wave in front will keep the engine bay relatively dry and your breathers up out of the way.
Rear fire wall up the top should be fine.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever. WARNING: Towballs used for recoveries can, and do kill people and damage property.
Any good 4x4 shop should be able to sell you a f/r diff breather kit.
or like me source the parts and DIY, then you know its right .
Plus you save yourself some fitting $$$$$$s

Did my GQ and dads GU, got 20m of 6mmID rubber fuel hose, some clamps, a bit of sikflex, and some inline fuel filters. Mounted them at the back of the firewall, putting a loop at the top to hopefully act as an airlock should the need ever arise. Had some fuel hose left over, but it's a straight forward job. First car took a bit over an hour to work everything out. Second car was done in about 20 minutes.
This is something I'm going to have to look into as well. The GU that I'm buying is completely unmodified so has a bit of work to be done. Is the breather hole easy to find or is there somewhere that shows this kind of info on this forum already?
Very easy to find mate. They sit on top the diff and the rear one runs to a cross memberbut I cant remembrr where the front goes but you can do it for under 25$
