Oil in intake

[SCOOTA44]

When I had the spark plugs replaced I noticed that there is a coating of oil in the airintake tubes,is this normal?

This is completely normal. This is part of the recirculation of the PCV (Positive Crankcase Ventilation) system. Instead of me trying to explain it, it would be better to have a read of this if you want to know more:

If you are that picky about it, you can fit a catch can in-line with the hose involved in this but realistically, you don't have to worry.

Thanks Daryl,I understand the way it works. probably should have cleaned it with carby cleaner while it was apart,anyway as long as it doesn't effect performance, all good.
