My Mini is spitting oil, it's a 1992 mini Cooper ive noticed that it's been spitting flecks of oil from the exhaust but i have no idea what it could be any help would be hugely appreciated

Is it realy oil or just condensed water & soot? The later would be quite normal this time of the year... However, it's always worth to give the injection system a close inspection. Most common are vacuum leaks, causing an overly rich mixture which in turn causes lots of soot which settles in the exhaust. Check the vacuume lines & connectors. If they'r brittle the ECU gets wrong information.

Ok thanks very much I'll have to check the lines etc

It'll be water and soot, not oil.
Any oil would be burnt either in the engine, or the exhaust manifold, and appear as blue smoke. If it's water, it will eventually condense in the exhaust, then wash the soot off as it comes out of the tailpipe.
Very usual in this weather as the air is very damp as the moment.
