Air leak in breather tube

So, after wading my truck I decided to run a breather extension for the rear axel.

After the job I thought I'd test it out (by blowing into the tube) and I realized there's actually an air leak at the coupling (where the OEM tube joins the rear axel).

That is, I could hear air escaping through that coupling when I blew into the breather extension.

I tried tightening the coupling to no avail. Is this normal? Seems like it could be a source of water ingress...

Let's hope the banjo bolt stripped and not the axle case

You may have a seal failure at the nipple and the vent tube. I would cut it off and re-install. Also the bolt assembly uses two copper washers to seal the unit .

The bolt isn't stripped. It's on there tight.

It looks like there's a copper washer that is supposed to be on either side of the bolt. I only have one copper washer so that might be the cause.

I'll try getting another and update.

well, the problem was the missing copper washer. With both washers it seals well.
