Oil in air filter housing

[jamesandtheopenroad]

Afternoon guys and gals.

Found some oil in the air filter housing today amd some mayonnaise in the breather pipe.





I know you get a little vapour and mayonnaise during short journeys in the cold and the last time I had the housing apart was about a year ago (when I found about the same amount) but wondered if this was excessive?

Thanks in advance.

I always thought that if you have mayonnaise in a water cooled the head gasket has gone,have you got any on the dip stick? Or any oil in the header tank.?
