Oil system myths

A engine oiling system is leaking from the time it leaves the pressure side of the pump. It leaks around main bearings, rod bearings, lifters, rockers. Just cause you have 70 psi at the discharge side of the pump does not mean you have 70 at the rockers. Imagine fighting a structure fire with a 1 3/4” 200’ long line that is figured to flow 200 GPM but along the way hose is full of holes and the couplings are loose. Just because you have the discharge gauge set at 180 PSI Doesn’t mean your getting 200 GPM out of the nozzle! Same with a engine oiling system. Biggest difference is the engine oil system is designed to leak.
