Known issues reported by owners and MOT testers.
- V12 Timing Cover Oil Leaks(Moderate)
Like the V8, the V12 is prone to weeping oil from the front cover. On the V12, this often requires the entire front end of the car to be dismantled.
- V12 Coil Pack & Spark Plug Failure(Moderate)
Heat soak in the V12 "valley" kills coil packs. Replacement requires removing both intake manifolds, making it a very expensive labor-heavy job.
