diff cover leaking

[5T1G]

Not known one to leak before, at first i thought it was the inner drive shaft seals but they seem fine. I've taken off the diff cover plate and the gasket looks abit fooked. Anyone else had this gasket leak before?

gearboxes love to leak. reassemble with pleanty of silicon (try not to let too much seep inside) and gack loads round the outside edge etc.

I changed that gasket on my old F13 yrs agao.

Btw I recommend the high temp, oil resistant gasket stuff from TOOLSTATION. About ?2.80 for a tube (silicone sealer gun size).
