摘要

Good oil pressure is critical to engine longevity, whether an engine is in a race car or a daily driver. Oil lubricates the bearings, rings and valve train components, and also helps cool the engine internally (especially the pistons and bearings). The two greatest concerns from a lubrication standpoint are dry starts and loss of oil pressure while the engine is running. Dry starts are more of a worry in engines that have front-mounted oil pumps with relatively long pickup tubes, which includes such popular engines as the GM 3800 V6, Chrysler 3.5LV6, etc. as well as late model Chevy LS engines, Ford modular engines and the new Chrysler Hemi, But even engines with crankcase mounted pumps and short pickup tubes can experience dry starts if the oil pump has not been primed prior to the engine's initial startup, or if the pickup tube or screen is restricted.
