Abstract: An engine gas-oil separator for separating oil contents in blow-by gases that are recirculated into an intake system includes a head cover, a lower plate, and a plurality of baffles. The lower plate attaches to the head cover to define a separation chamber between an upper internal surface of the head cover and a lower internal surface of the lower plate. The separation chamber includes a blow-by gas inlet, a blow-by gas outlet and at least one oil outlet. The plurality of baffles are disposed in the separation chamber between the head cover and the lower plate. The plurality of baffles, the upper internal surface and the lower internal surface define a swirling flow path through the separation chamber in a longitudinal direction between the blow-by gas inlet and the blow-by gas outlet. The plurality of baffles are also configured to direct the blow-by gases in a generally transverse direction.

Abstract: A valve operating mechanism includes a pin housing housed in a lash adjuster and a lash adjustment chamber. A sync pin is slidably received within the housing between an activating position and a deactivating position. A ball valve assembly is provided within the housing for communication with the chamber, and is moveable between an open position and a closed position. The valve operating mechanism is operable in an active mode and a deactive mode. In the active mode, the sync pin is in the activating position, a valve is in an active state and the valve operating mechanism is configured to adjust valve lash. In the deactive mode, the sync pin is in the deactivating position and the valve is in a deactive state. The valve operating mechanism is configured to generate valve lash to allow the operating mechanism to move between the active mode and the deactive mode.
