A crankcase blowby disposal system for a reciprocating engine comprising a heat exchanger in fluid communication with an oil filter and the crankcase in which blowby comprising oil droplets, oil mist, oil vapor, water vapor and other gases, the blowby is vented from the crankcase, passes through the heat exchanger which cools the blowby to a temperature below the dew point of the oil vapor and above the dew point of the water vapor, whereby the oil vapor condenses and the water vapor does not condense, then the cooled blowby passes through an oil filter which removes essentially all the oil from the blowby, the oil free blowby is then returned to the engine intake or exhaust or vented to the atmosphere, the oil collected in the oil filter may be returned to the crankcase.

[ What is claimed is:] [1.] A crankcase blowby disposal system for removing oil from crankcase blowby which comprises water vapor, oil vapor, oil mist, oil droplets and other gases, collecting in a crankcase of a reciprocating engine having an after cooler disposed up stream of an inlet gas manifold which provides an after cooler exit gas temperature, the system comprising a heat exchanger disposed in fluid communication with the crankcase so as to cool the crankcase blowby that pass there through, an oil filter disposed down stream of the heat exchanger for removing oil mist and droplets from the crankcase blowby, the heat exchanger being designed so that the crankcase blowby is cooled to a temperature equal to the after cooler exit gas temperature which will condense the oil vapor and will not condense the water vapor, whereby the condensed oil vapor is now in the form of oil mist and droplets that will be removed by the oil filter, while the water vapor passes through the oil filter.
