All the front running gear in a d22 has breather tubes up into the engine bay. There are a few limited models that have the rear diff breather extended up to just under the tray from the factory. Mine wasn't. Very simple to do, and worth it for peace of mind.

does the front diff breather run up into the air filter box?

Nope. Run's to the skirt in the engine bay, as does the gearbox and transfer case.

cool, will do this mod over weekend as its fairly cheap and looks easy
Runs up then to a silver small diameter metal tube just beside it in my 2010 model. Can get a pic tomorrow.

My 2005 d22 zd30ddt has 3 vents in the bonnet I'm assuming gearbox transfer and front diff, and there is another attached to rear diff I couldn't quiet follow.
1. A breather not sure where from next to air box
2. Another on back wall there above brake cylinder
3. And another down there amongst all those wires.
4. My rear diff does have a breather. Couldn't quiet follow it just yet. In work clothes and ground is wet.

Hmm maybe it's the rear diff. I'll follow the line i found from rear diff tomorrow. Anyone else have a line running from rear like mine?

Its the metal part that the hose slips over on your diff for the breather.

Jap. Thy may be fitted with aftermarket breather. Standard breathers on d22 usually only run up to chassis rail. That gearbox/transfer and front diff go into the engine bay. The rear goes to the chassis rail and in some models it only has a one-way valve just on top of the diff

Ahh
Gotcha rusty, looks like it runs to chassie, but couldn't tell properly. Dave. If I went to repco. "should" they know what a diff breather valve is? Or Nissan?

Not likely. I tried that. I ended up going to a hydraulic place and getting a 1/8th BSP barb and some hose. tapped the hole out to that and BAM! New rear diff breather.

And the barb just screwed into the diff that easy after removing factory plug?

I just bought some bits to do this, and i got 1/8 fittings. I was thinking these would be the correct size as all i can find is people referring to 1/8", guess i was wrong if you had to tap yours out.
Does anyone know the actual size thread for the fitting need?
If not ill pull mine out and measure the thread and post it up here.

Maybe give your local Enzed a go. I have also read Nissan Dealerships may have them but not 100% sure on that. Or buy one online.
