SummaryN63 and S63 Engine: Valve Seal Replacement. Refer to the following applicable SIBs before replacing the valve seals. * B11 07 11 - Turbocharger Failure: Oil Supply and Return Line Blockage and Proper Repair * B11 07 12 - N63 Engine: Oil Consumption and/or Rough Running Complaints * B11 01 13 - N63 Engine: Engine Oil Consumption, Engine Oil Top-ups and Refill Capacity * B11 03 13 - Engine Oil Consumption (all models) If the valve seals are leaking, one of the following will help determine if the seals should be replaced. * Smoke from the tailpipe when starting or aggressively accelerating and decelerating the engine in addition to excessive engine oil consumption * Spark plugs fouled with engine oil and excessive engine oil consumption * Excessive engine oil consumption All Vehicles: On vehicles, where an excessive oil consumption between services is the only complaint, a complete oil consumption test as described in SI B11 03 13, must be performed first before replacing the valve seals. On vehicles exhibiting reproducible smoking from the tailpipe when hot, additional engine diagnostic steps (e.g. engine compression test, leak-down tests; inspection of the crankcase ventilation lines and turbo intake/outlet tubes for excessive oil accumulation) should be performed and documented prior to replacement of the valve seals, in order to eliminate other possible causes. Refer to the SIBs listed above for important diagnostic tips. Do not remove the intake manifolds to clean the intake valve carbon.
