At sea while enroute found Aux. engine sump rising slowly by ½ cm a day; checked all possibilities for oil passing by and blocked all lines. Sump oil kept rising.

Finally oil started leaking from crankshaft flywheel side seal and spraying, so generator had to be started immediately. To our surprise found sump level dropped to normal.

Immediately suspected Breather pipe choked, cleared the breather pipe and fitted back. Also found one unit blowing past badly, replaced rings of that particular unit, and found all running satisfactorily.
