Thread: replacement front diff breather Disco 3 and 4

So after reading this thread, i was intent on replacing the breather. Picked one up from LR today and popped the bonnet when i got home, only to be greeted by this





Mine is a 2013 model and ive had it since Feb this year. Me thinks i probably should have opened the bonnet earlier and checked.

Well, at least you've now got a spare if you ever need it.

Wow - that's a lot of coin for a 90 degree elastomer bend with a filter? inside and an end cap!?
Considering we are mainly keeping under bonnet dirt and splashed water spray out of the diff breather tube, would a cheaper option be to install a sintered bronze fuel filter instead?

You can get these for $5-10 bucks at a local mower shop (not fact-checked but online anyhow). There are different types with and without the plastic tubing over it.
Can someone convince me why I shouldn't use one?
Thanks Matti

None at all and I share your dismay! It’s extortion for what it is.

So I did mine today

$20 worth of bits from supercheap


Existing line cut


New bronze filter fitted


And looped and zip tied off


Hardest thing was cutting the old filter off with a razor blade. As far as DIY jobs go this is easier than changing the internal light bulbs!

Any joy with identifying the rear and TC ones Dan?

Haven't tried yet. I plan to get under there and have a good look tomorrow. Gotta check and see of the front diff is actually leaking too. Fingers crossed!

So the rear diff breather appears to follow the rear aircon lines at the rear right wheel arch. I didn't take the arch liner out and couldn't trace it any further. I pulled the jack holder out but couldn't see it in there. I'm assuming its next to the air con system behind that rear panel, so is probably fairly well protected, but one day I will confirm that.

Couldn't find the TC breather. It needs to be pulled out to fix a leaky seal though so I can update when I've done that. Won't be til late Jan early Feb though

Cheers

Dan
