Abstract
In a transversely mounted engine, oil intake efficiency is improved by a sloped baffle which funnels the returning engine oil to the oil intake in the oil pan, a small clearance between the baffle and the pan to retard oil surge beyond the baffle, a dam adjacent the oil intake port to inhibit the formation of a vortex that draws air into the port, and optimum placement of the intake in the pan.
