Is it the fly end though?
Could be cambelt end.

I hope so I'm going to phone about for a few quotes I think

I had similar on an R5GTT, coating the clutch in oil causing it to slip like a bitch. It was an engine out job on that but you may get away with box off at a guess?

I just got told today that I've got an oil leak from my crankshaft seal,its a very small leak but just wanting to ask is this a big job to replace,is there alot of man hours in fixing this. any help apretiated thanks
