Hi
just fitted one of these to my cossie I fill it it to the
level plug with millers crx ls 80w90 oil it seems to be
making alot of internal pressure in the diff because it's
blowing oil out of the breather I put in an extra long
pipe all up to the filler cap it's still coming out have I
overfill it or using the wrong grade oil it's semi synthetic
trannmission oil but it does say suitable for LSD or
should I be using a oil which is more LSD only type
cheers for any advice Bill

 

i have 80w140 in mine did u just fill it to the level u havent over filled it have u odd its blowing out the breather. Must be that the oil you are useing is to thin! I was was told buy tom gripper to put 80w140 in mine when i brought it
