Oil feed tubes break and fall into the crankcase (engine) and the tappet becomes noisy (ticking), resulting in degraded idle quality. Our technicians recommend replacing all of the tubes at the same time, broken or not.

Oil tube ends popped off resulting in lowered oil pressure and ticking noise. Replaced myself with upgraded steel tubes
