Abstract: An engine oil lubrication system includes an oil flow control baffle disposed in the sump of the oil pan. The baffle may be detachably mountable in the sump of the oil pan. The baffle may be configured to prevent oil returning to the sump from the engine from short-circuiting and flowing directly to the oil pump intake. The baffle creates a circuitous flow path which forces mixing of the returning oil before being drawn into the oil pump intake nozzle via increasing resonance time of the oil in the sump to enhance cooling. The present disclosure further provides a modular engine mounting system which extends the number of engines and vehicle chassis which can utilize a single oil pan to mount to the chassis. Interchangeable mounting flanges are provided having different bolting patterns compatible with the different chassis.
