What are the reasons for crankcase explosion?

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.

What does hose from crankcase to air intake do on 98 mystique?

it allows your crankcase air to prevent a "vacuum" from occurring, it may also release small amounts of oil from your CC back to the intake which essentially gets pulled back through the engine

What is the function of piston rings in engine?

Isolate the combustion chamber above the piston from the crankcase below the piston, so that the pressure does not blow-by the piston into the crankcase. Also they ensure an even spreading of crankcase oil along the walls of the cylinder to prevent wear. They also provide improved thermal contact from the piston to the cylinder walls, which are cooled by the cooling system.

What is the function of a pcv valve?

The purpose of the PCV valve is to regulate the flow of crankcase fumes into the intake manifold where they can be burned. Prior to 1963, cars had no PCV and used road draft tubes that just left the hydrocarbon emissions from the crankcase out into the open air. The PCV valve also has a secondary role as a check valve, to prevent flow back into the crankcase. This prevents potential ignition of the crankcase fumes, should the engine backfire. The PCV system is also crucial for to proper engine sealing. The system alleviates crankcase pressure, which can push out on seals and gaskets, contributing to oil leaks.
