Ok so,
Where are the breathers?
And what is the best way/thing to do to get them ready for offroad?
I.e raising them
Cheers Cam

There was another member on here recently asking the same thing. Do a search for that thread for pics.
The front diff/gearbox breather - use the dipstick hole
The rear diff, remove it and you'll find it caked under layers of grease in dust (under shroud on the moustache bar). It's a white-ish little thing. Use some pipe to move it higher. I'm going to be running mine up into the engine bay and into the air intake behind the filter - I'm still planning this so it could be a while.
Cheers

it was a BOOsting post, I supplied the photo and only just cleared it off my PC yesterday !! Rear diff breather is hidden behind the moustache bar so you need to drop it to find it

And a 1/2 inch right angle poly pipe fitting fits in it just with a little tape and then run it to where ever you want and then put the original Breather on the end

Awesome thanks Matt,
And the engine bay is generally the spot?
And the front doesn't have one?
Cheers Cam

My breather i ran up to the inside of the ute back and tied it to the fuel tank breather

Also i should have clarified the Poly pipe angle needs the barb cut off to fit in.

Cool, I found some cheap kits on eBay that look the goods.
The fuel tank has a breather too?
Anything else that needs attention before going offroad?

hey mate,
it was me. i'll find photos of what i've done so far, sounds like we are on the same modifying path!
have a look at my build thread, its missing heaps of photos but that should be fixed in a few weeks.
i just posted in your snorkel thread also.

If you remove the plastic breather ( tap it out) a brass barb BSP fitting will screw in, then run it with the fuel pipes up into the top rear quater panel. The subie will float before it gets up there.
Good luck

Thanks tambox.
Could you please elaborate on this?

Ok,
This depends on how good the white plastic breather is on your diff:
1. If it is good and strong your can angle a wide blade screwdriver from underneath and tap it up words, TAP being the key word.
2. if it breaks, grab it with some long nose pliers, a good set, and you can work it it out. Clean around the breather first.
There are no sleeves or ridges, it just slides out.
From memory, although many drinks whilst working on many Subies have damaged this, a half inch BSP straight barb will screw in. Take your old breather for a reference.
Add sealer/ thread locker as you screw it in.
Add a length of 3/8 hose with a hose clamp to the barb.
Run it along the diff hanger (drill a couple of holes to cable tie it on) over to where the fuel hoses go up.
Remove the panelling to get access to this area.
Run the 3/8 hose up to above the rear guard.
If your Subie gets water into that you are submerged

)
Buy a boat.
Many years of dunking Subaru's has shown this works.
Good luck

This depends on how good your plastic breather is.
Clean around your plastic breather.
1. Use a wide flat blade screwdriver to tap the breather up wards from undereath.
2. If it breaks, use a pair of pliers, good long nose, to wiggle it out.
There are no sleeves or ridges, it just slides out.
From memory, (do not quote this) a half inch/ to 3/8 BSP barb will screw in.
Use thread lock or similar when screwing in.
Take your old plastic breather as a reference.
Add 3/8 pipe, with a hose clamp to the barb.
Run the 3/8 hose over the diff hanger, drill a couple of holes to cable tie it on.
Run up with the fuel lines.
Remove paneling to get access to this area and run the 3/8 hose up to the top of the gaurd.
Loop the top end so it faces down, (gives a vac lock when diff is cool).
If you get water in here you have submerged you Subie, buy a boat

)
Good luck.

Thanks, any pics would be very very much aprichiated.
So the breather is in between the outer paneling and the removable panels in the tray?
What is a barb in this context?
Now the front diff/gearbox. Does it really need one?
Thanks Cam.

Hey tambox, are you talking something like this?
Is the hole that the existing breather sits in threaded, or is it just about the right size?

the access panel to the Brumby fuel tank breather box is just rear of the fuel filler position inside the tray on the wall . Two screws hold it in place.
Think the front breathes through the filler dip stick tube ??

Only problem is that subi's don't float, not when they're stuck anyway:

I'd say that he is - from his description you slide it in the breather's hole with some sealant around it. I've used a plastic one from bunnings that's meant for sprinkler systems, shave one barb off and shove it in, nice and tight fit.
Don't use the cheap plastic hose that this barb is used with on a garden system, I ran it along the moustache bar up into the cab near the fuel filler point, only to have a rock pierce it and almost empty out the diff of it's oil...

I took the cover off mine, drilled and tapped to suit a 1/4 BSP barb (like pictured above) and ran the hose high up in the wheel arch. Has worked great.

I just found this while looking for another image. Moustache bar is missing so you can see what's been done:
I also like the way he's "lifted" the rear shock/strut ^ If anyone know's their early subaru rear ends will see that the lower mounting point for the shock/strut has been raised.

That's pretty much what I was picturing.
I would love one of those silver stickers on my diff...
