Low oil pressure
A warning light or low gauge reading with the right oil level and a good sender often means a worn oil pump.
Engine rebuilds
Fit a new oil pump whenever the engine is rebuilt or the bearings are changed. Worn gears undo a fresh rebuild.
Noise from the bottom end
Rattles at start-up while the pressure builds are a sign the pump is not priming quickly enough.
Fitting tips
Prime the pump with clean oil, fit new gaskets and O rings, and check the pickup screen before closing up.
