Breathers & Nissan Snorkel???

[10G]

On a 2013 Y61 3L CRD do we have gearbox breathers? Is it a good idea to fit breathers, or aren't they really necessary?

I've not done anything with the front breather as it goes half way up the firewall anyway, should I extend it?? Where have others mounted the front diff breather?

Rear diff, I have extended that breather, out & into & up to the top of the fuel filler cavity. Where have others placed their rear diff breather???

And the stock Nissan GU ex Airtec snorkel. Do I need to do anything to it to make sure it's water tight????

Thanks for any help.

All depends on how stupidly deep we plan on or maybe accidentally taking our trucks underwater 10g Mate. Gear oil hates water as it emulsifies up like a cappuccino creamy froth and bang goes your gears.

Where are the breathers for the gearbox & transfer case?? Does it have any??

It definitely will have breathers for both boxes 10g Mate. There should an approximate 6mm hard tube line coming down from above somewhere near the gearbox to transfer case connection on the passenger side.

Yeah they are hard tube running along the passenger side chassis rail then up into the left corner of the left wheel arch. They are connected to the gearbox with a rubber hose and also to the diffs the same way. Chase from the diff and you will find all of them. The gearbox one will run parallel to the rear diff one. I cant imagine this being very different for the 3.0, both my GQ and GUIV are the same setup.

If you plan to go into deep water you should sort it. The air box/snorkel joint at the inner guard is nowhere near water tight.

Cut the flange off the air box inlet, and the front off the snorkel tube inside the guard.
A Sonic Performance brand 4" x 3.5" silicone reducing elbow is a perfect fit at both ends. I got mine from MTQ.
It smooths out the shocker of a bend, and fixes the air box seal at the inner guard, all in one go......

Nice one. the breathers should be find up on the back of the fire wall up high. You can go into the Snorkel but for the most part the fire wall will be fine. The suction caused by them cooling when you enter the water will pass quickly i reckon. if you come to a stop in the water and flood the engine bay to the underside of the bonnet then the diff is already cooled. And..... you have bigger problems. lol

Another good water proofing improvement form factory is to seal up the clutch a bit better (assumimg its a manual). Worth siliconing around the fork boot both ends and also the little bung at the bottom of the bell housing. Can pull it out every service or so often to check theres no water that's got in or oil that might have come from rear main.
