Question about Cars & Trucks
The engine oil pump draws oil from the oil pan or sump under the engine. Most designs place the pump withing the sump for convenience of design and efficiency of operation and in particular to provide the shortest time to achieve full pressure after a cold start and possible drain-back. Some designs, mostly push-rod engines, drive the pump at half crankshaft speed but modern design tends to mount the pump on the front of the crank driving direct or close to the front of the crank via a chain or gear drive
A few designs placed the pump at the top of the engine and sharing a timed drive with the distributor. Surprisingly these worked quite well until the engine had lost it's newness and then the length of time until oil light out would extend and extend and extend. It was reckoned this wasn't a cause for alarm until it took one minute...
