Oil Leak Detection — Mercedes Engines
Common oil leak points on Mercedes-Benz petrol engines: valve cover gasket (most common — brown residue on top of engine, burning smell), camshaft adjuster solenoids (VVT solenoids — cause misfire codes if oil contaminates the plug wells), and the crankshaft front seal. For turbocharged models (M270/M274), also check the turbo oil feed and return line banjo fittings. Valve cover gasket sets cost for parts; workshop labour adds . Any oil leak near the timing chain area must be repaired promptly — oil saturation of the chain tensioner causes premature failure.
