Abstract: An internal combustion includes a crankshaft and a camshaft rotatable by the crankshaft. The internal combustion engine also includes an oil source, an engine cover, and a drive member disposed within the engine cover for transferring rotational motion from the crankshaft to the camshaft. A camshaft phaser actuated by an electric motor is disposed within the engine cover for controllably varying the phase relationship between the crankshaft and the camshaft. A supply passage communicates oil from the oil source to the camshaft phaser in order to lubricate the camshaft phaser and a drain passage drains oil from the camshaft phaser to the oil source. A sealing arrangement defines a dry zone within the engine cover to isolate the drive member from oil used to lubricate the camshaft phaser. The sealing arrangement includes an electric motor to camshaft phaser seal to seal between the electric motor and the camshaft phaser.
