Report: Poor idle quality due to oil feed tubes falling into crankcase
Mercedes-Benz 400SEL Problem
Model Year Affected: 1993
Verified
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.
