Timing Chain Guide and Tensioner Wear (P0017)
SeriousEngineThe gasoline Ghibli's 3.0-litre twin-turbo V6 (F160, assembled by Ferrari for Maserati) uses plastic timing-chain guides and hydraulic tensioners that turn brittle with age and mileage. When a guide cracks, the chain slackens and valve timing can jump, logging crankshaft/camshaft correlation fault code P0017; tapping or rattling near the valve covers on cold start is the classic early warning. Broken guide fragments can fall into the oil pan and block the oil pickup, starving a turbocharged engine of oil and risking bearing damage or a seized engine. The repair needs a Maserati factory locking tool and roughly seven to eight hours of labour, and risk rises when oil changes have been skipped or the wrong oil used.
Tapping or rattling from the top of the engine on cold start, Check engine light with timing-correlation codes such as P0017, Rough idle or uneven running after starting, Engine fails to start or loses power in severe cases
- Listen for tapping or rattling immediately after a cold start
- Ask whether chains, guides and tensioners have been replaced, and at what mileage
- Scan for stored timing-correlation fault codes before viewing
- Confirm service history shows frequent fully synthetic oil changes
