My rear diff seems to be very oily i haven't had chance to have a good look, is there a gasket set for it or does anyone know if this is a normal problem ?

There is a gasket between the diff and the cover plate. This gasket will be a dealer item. If you are lucky it is this gasket which is an easy repair job.
Inspect carefully the inspection cover which also contains the drain and refill bungs. These can crack if some ham fisted person over tightens either of the bungs. I have come across this several times now, first time courtesy Pete Croney of the original scooby sport.
If it is neither of these then one or other oil seal to the driveshafts is U/S.

 

Still haven't had chance to look at it and probably won't over the next few weeks but i might get the gaskets anyway they can only be a few quid so if i am bored on a Sunday i can give it a go !

 

I think you will need to drop the whole diff out of the car to do the rear cover gasket properly with oil-free surfaces achieved before bolting back together.
If you take the diff right out changing the oil seals is very very easy at the same time.

 

Sorry. I have to disagree there. Changing the gasket in situ is a doddle. Drop the oil out and maybe even let it stand with the cover off overnight.
Ensure the old gasket is totally removed and use a blunt table knife or similar if you have bits of gasket still to remove on both mating surfaces.
Clean both mating surfaces, apply the new gasket, no paste required, ensure it is in the right position and torque up carefully in the correct sequence.
Ensure you refill with the correct oil to the bung level. Probably .8 litres but whatever is needed to get to the bottom of the filler hole.
It will also help if you steam off or pressure wash the diff the day before the inspection. It makes locating the leak that much easier.
If you are not going to sort this in the next day or two make sure you do not run the diff oil level low.
Total job time including jacking the car up will be an hour, perhaps less. 15 mins the night before and 45 mins max next morning.
