Thanks AWG. The above link describes the differences between 242s over the years. If this site is correct, there are differences between 95 and 96 cases, but interested to see where the breather is on the 96.
The pictured 95 model year 242 case in the link above displays two metal pipes on the opposite side. In my case, something must have shot out and has left a machined hole open allowing oil to leak (10cm diameter spotting on the ground). I have no pictures of the location of the hole as it is currently on a hoist.
The car runs fine, the T/case works fine. It is just that we are unsure how to plug that hole!
It wouldn't surprise me if there is 96 t/case in the 95.
