@Peterfalk78

Ive attached images with an arrow to where the oil was bubbling.
Therer also appears to be a leak above judging by the pipes, but i not sure if this would have the oil bubbling on the bolt .

My opinion is that there is a worn O-ring that needs replacing.
There is a screw at the top that holds that filler tube in place.
Remove screw, lift up the tube, replace the O-ring and push the tube back in, replace screw.
if it is exactly where your arrow is, there is a crack in the housing? maybe the housing bolt was loose and vibration cracked it, or it was over tightened.

thanks, i really hope the housing isnt cracked as im not sure how to fix it ,

so i will look at it in more detail, i hope its an o ring seal or something
