W16 Engine Oil Leaks and Consumption
SeriousEngineThe 8.0-litre W16 engine uses a complex dry-sump lubrication system with multiple oil circuits. Valve cover gaskets, turbo oil feed lines, and sump seals are prone to degradation from the extreme heat cycles. Oil consumption can increase significantly on higher-mileage cars. A full reseal of the engine is a major job requiring body panel removal.
