The Mysterious leak PICTURE HEAVY

[LewisG]

I would say you have both.

Did you replace the drive shaft seals when you changed the gearbox?

Is the oil filter on tight enough and did you use a new copper washer when you did the last oil change?

Drive shaft seals were fine according to my step dad and No i didnt change the copper washer last time. Im going to have a good look tomorrow so will check the oil filter. When I replaced the gearbox I went to drain the one I was taking out and no oil came out so that raises my suspicions of a gearbox leak.
