Sounds like just droplets of water?

in fact you could well be right, so when the exhaust heats up they evaporate before they get out. as long as its not oil so as a sign the engine is going to break thats great. cheers.

Chances are its not oil, only way for it to get out through to the exhaust is through the combustion chamber, and by then it will have been burnt and will plume blue smoke.
