A gas-oil separator includes a bowl shaped housing open to the bottom for mounting to the rocker arm cover of an internal combustion engine. The housing and an encircling gasket at the bottom is secured to the rocker arm cover by a pair of bolts passing through the top of the housing and threaded to a clamp plate positioned inside of the rocker arm cover. First, second, and third baffles are secured to the clamp plate and sequentially spaced therefrom so as to be disposed within the housing. The clamp plate contains a pair of openings for the flow of mixed engine blow-by gases and oil, and a pair of holes for exit of the separated oil; the housing contains an outlet port proximate the top for the exhaust of the separated blow-by gases. The first baffle plate contains three openings which are completely out of line with the two openings in the clamp plate. The second baffle plate contains a pair of openings which are in line with the openings in the clamp plate and out of line with the openings in the first baffle plate. The third baffle plate contains three openings which are in line with the openings in the first baffle plate and completely out of line with the openings in the clamp plate and the second baffle plate. The openings are positioned so as to cause impactive precipitation of the oil on all three baffle plates and to cause complete retroversions of flow for centrifugal precipitation around the first and second baffle plates and sedimentary precipitation between each of the baffle plates and above the third baffle plate.
