Rear Diff slight drip of oil Evo 6?

There is a square bit on the rear diff looks like a cover with 4 bolts in each corner that holds it on.

What is that cover and is there a gasket for it?

Mine is leaking from that cover.

Thanks

It is an inspection plate for the inner workings.

From memory there is a gasket behind it but it's not listed in the parts list.

34046 is the plate. It’s a slight leak nothing majorly. What is the best way to re-seal it? Gasket paper?

No oil will leak out if I take that inspection plate off?

Never touched the diff before

It opens directly into the inner workings so most of the oil contained within will leak out if you open it without draining the oil.

Good opportunity for an oil change.

I'm not sure whether the seal is paper, rubber or sealant but I'd replace like for like.

Even the workshop manual doesn't mention a seal.

The worst thing is I have a new rear AYC diff sat in the office that I could check but I'm at home.

The bolts are torqued to 9Nm.

Could you have a quick check please when you are next back in that would be highly appreciated! Thank you for all the diagrams and help

No gasket at all.

Maybe a thin bead of sealant will fix it?

Absolute legend! I am being cheap now. Maybe all the oil may not come out if I undo the cover as it can’t be filled to the top with oil. Silicon will be the fix.

It is (or should be) filled to the bottom of the fill hole as in the picture.

The full amount is 0.41 litres.
