Diff vent pipe
Diff vent pipe: what is it? What does it do? Do I need one?
My Sierra diff seems to have come without this, but I see it on lots of pictures from other builds. Mine does have a small black plastic cap on top of
the diff and it looks like there was once something attached to it but it must have broken of.
So am I missing something important?

Problem is that the part of the nipple that holds the tube is broken of.

My diff needs a tube about a foot long otherwise it chucks oil out all over.
I can't imagine doing without will keep all the oil in.
The 'nipple' is only a plastic push in thing I guess it would only be coppers from ford.

Diff vents just vent the pressure from the expanding gasses as the diff fluid heats up and keeps the dirt/water out. Otherwise the pressure will blow
out the axle seals.
Some are just a little tube with a loose cap on it, and some are hoses that go up and curve down to keep the water out.
Seems a little odd you are losing a lot of oil out yours mookaloid, is it right above the ring gear or something?

Diff Vent
Mine lost a bit of oil (and it was filled with the correct amount) so a long tube was fitted.
I also put a fuel filter (one of the push on plastic ones) on mine as I was worried about dust etc getting in the diff.

Its just one bit. The cone end presses into the diff so you might have a bit of a wiggle to get the old one out.
