Oil Pump: Description and Operation

The oil pump is bolted to the front of the cylinder block and is crankshaft driven by a trochoid gear. A full-flow oil filter is mounted to the engine oil cooler. Both are located at the front of the cylinder block. Under normal operating conditions, all of the engine oil will pass through the oil filter. If this oil filter becomes clogged or blocked, the oil will be routed through a bypass valve, directly to the engine.
