Abstract
An engine system optionally including: a crankcase of an engine having a blow-by gas passing therethrough; a liquid source containing a liquid; and an oil separating apparatus in fluid communication with the blow-by gas. The oil separating apparatus having a coalescing filter to separate oil from the blow-by gas. Separate from the blow-by gas and the coalescing filter, the oil separating apparatus is in fluid communication with the liquid source to receive the liquid. The liquid is passed through the oil separating apparatus in a heat exchange relationship with the blow-by gas to maintain a desired temperature range for the blow-by gas.
