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.......
