Be sure the PCV (Positive Crankcase Ventilation) system is in good working order.
high temperature due to the reciprocating movement of the piston, increase in bearing temperatures, sparks entering the crankcase due to leaky piston rings or piston blow past, fires in the adjacent scavenge trunks. Now, when these hot spots come in contact with the oil in the crankcase, the oil gets vaporised. When these vaporised particles travel to the cooler part of the crankcase they get condensed into a white mist which has oil particles properly dispensed in it. The process that takes place is some what similar to atomization. This white mist when again travels to the hot spot area, can easily catch fire, which might also lead to an explosion. The fire or the explosion create immense pressure inside the crankcase and if this pressure crosses the permissible limit, crankcase explosion takes place. The explosion will rupture the crankcase doors and even cause heavy damage to the inside of the engine.
An immediate explosion can occur at any moment.
