We observed a white smoke from the auxiliary engine crankcase (crankshaft seal). The engine was stopped immediately. What may be the cause of the smoke?
Open crankcase covers. Check the crakcase/sump for any signs of cooling water leakge.
The white smoke mentioned may be vapours or droplets a oil-water mixture, especially, if water leakage is significant and level of contaminated oil in the crankcase have reached the crankshaft webs / connecting rods. In this case, rotating crankshaft splashes the oil-water mixture, creating white fog and excessive pressur in the crankcase, whiche releases itself through crankshaft seal.
