Aircraft engines don't use tightly fittet cylinders as they are old air cooled designs with large temperature spread. Therefore there is a lot of blow-by past the cylinders ending in the crankcase. The stock solution is to use a 1 inch hose and just dump those fumes out the bottom of the engine compartment leading to oil and dirt accumulating on the bottom of the fuselage.<br> | Aircraft engines don't use tightly fittet cylinders as they are old air cooled designs with large temperature spread.

There are designs that separate the oil and return the oil into the oil sump and only dump the cleaned fumes out the bottom. Drawback is that not just oil condensates in the separator but also water and therefore water is returned back into the oil pan.<br> | There are designs that separate the oil and return the oil into the oil sump and only dump the cleaned fumes out the bottom.
