Abstract
A method of coking entrained oil from blow-by gas (F) of an engine (14) in a closed breather assembly (16) includes the steps of transporting the blow-by gas from the engine to a mist separator (18), transporting the blow-by gas from the mist separator to a breather coking device (12), heating the breather coking device at least one of conductively and convectively with an exhaust manifold (32) of the engine, coking out at least a portion of entrained oil from the blow-by gas and depositing the coked oil at the breather coking device, and transporting the blow-by gas from the breather coking device to one of a turbocharger compressor (24) and the engine.
