ABSTRACT:
A valve trains drive assembly for a V-type engine which includes a balancing shaft. The valve train includes a flexible transmitter between a crankshaft sprocket and one of two camshafts in the cylinder heads as well as a sprocket around the balancing shaft. Each of the camshafts that are driven directly by the crankshaft then drive the opposed camshaft within each cylinder head via a transmission. The transmissions within each cylinder head between camshafts may be located at the forward or at the rear end thereof. Both the intake camshafts, or both the exhaust camshafts, or a combination thereof may be directly driven by the crankshaft sprocket. An improved breather oil separator is positioned between the balancing shaft and an induction system.
