That location may be for the coolant return if you use a differential cooler.

You might want to make some modifications to the rear end cover to be able to do some Oval or Road Course driving......
This set up has been tested under the most sever conditions....

I didn't either Pete.
It must be a special option so the cars can run upside down other there, or if you run over a kangaroo your diff will still be well vented
Dimis, I don't have that vent on our cover.

I think he has an older diff, he has a 3:42 ratio, mine is a 3:55, and at the open house all the lines pretty much are now steel braided where need be, and the aluminum diff is standard now.

Not sure have not got a car number yet, but im looking at December to have it on the road, the summer is here in AZ so its a no drive for sure for at least the next 5 months, unless I drive at night. lol, Its gonna be bad ass thats for sure, I got a few tricks up my sleeve, already named it Pride and Joy. Gonna do some drifting videos, as well as the mile all out run for top speed, even got a helicopter to shoot video for a short film for it. All in HD.

Thanks guys... I figured as much it being a breather... but what to do...?
Options:
1) Seal it off
2) Tee it in at the junction
3) Run 2nd separate breather
I'll mull on it.

Correct & correct again. I believe all are now braided as standard so not an option they'd discuss with you.

Hopefully no Roos where I'm driving... mind you some have been trained to dodge the traffic

Others not so well trained

FYI ...... we run 3 different Kirkham Diff with Quaiffe Differential in all three ..... and they were notorious for puking oil out of them ...... some folks had issues just driving on the street.....
Many folks had a problem with the oil going up to the catch can .... and filling the catch can up from the rear end....... Also you should notice the line drawn on the steel cover ....that shows the kirkham cover fill hole is to high and over filling is what a lot of folks did..... The aluminum Jag cover shows the correct height the oil level should be.....
We built this mod on the steel covers and tested at Road America/St Louis International/Road Atlanta...... and did not puke any oil out and were able to control our rear end oil temp down to 280*degrees from 320*degrees...... and yes we run a oil cooler and fan on our rear end cooler.......
