Oil leak Distributor area

I've got a small oil leak some where around this area. Drips onto the exhaust
and makes smoke. Never hits the ground, must only leak at high revs because I can never find it. I switch the O ring but it was not an exact match. Maybe it is leaking from distributor shaft or somewhere else. I heard this is a problem with the MR2. Any info will be welcome.

The dizzy can leak oil, so if you are leaking oil from around there that could defiantly be the cause. Take the dizzy cap off and look for oil inside. If there is oil inside, it's leaking oil. In that case, a new dizzy or a dizzy re-build kit (if you know how to re-build it, never done that before).

Thanks for your input. When I fitted the O ring I noticed a little oil inside the dizzy but it didnt seem to be enough to account for the amount of oil around that general area. There again apart from the cam cover there is nothing much else around there that could cause this. Anyway it seems to have stopped burning on the exaust system now so I must be getting close.
I've now got bigger fish to fry due to a new problem. Take a look at my new post. I would welcom your input. Thanks
