It is a common event. If you want to improve the IC effeciency there is a write-up on here detailing how to clean it out. Just make sure there's no fluid left in the IC before refitting as it'll likely get sucked into the engine.

As Mike says Pete, oil here is totally normal and nothing at all to worry about.

It comes from the crankcase breather. If you look at the pipe from the oil filler pot that goes to the inlet tract via the "capsule", that's the breather. The inlet suction sucks fumes from the crankcase and inveitably, some oil mist will be dragged in too, hence the oil.

It may actually be beneficial...
