I have a pro alloy mirror image tank on mine and the two pipes coming from the top which go to the flame trap and the cam cover have loads of mayo at the tank end of the pipes but not at the engine sides of the pipes and the tank seems to have a lot of mayo in it too, havent checked the sump drain or 1" air outlet yet. Is this just condensation or could this be a problem?

 

if its allot i would be looking at possible headgasket failure!

small amounts can be condesation at this time of year!

 

It wont be headgasket as their is no mayo at the flame trap, the cam cover, dipstick end or oil filler cap its all at the other end of the pipes where the tank is, i.e away from the engine

 

often just condensation mixing with the oil fumes etc
