motore PURETECH 1.2 a CATENA NUOVI PROBLEMI

The PureTech engine, particularly the 1.2 version, has had problems with the camshaft and the ring nut screws that secure the sprockets. Incorrect positioning of these screws can cause problems such as loss of power, warning lights and, in more serious cases, the timing or timing chain to move. A manufacturing defect has been found on the PureTech 1.2 engines, involving the positioning of the screws that secure the sprockets to the camshaft. Causes: This defect can be caused by the screws not being positioned correctly during manufacturing, resulting in the sprockets not being properly fixed. Consequences: Incorrect positioning of the screws can cause a number of problems, including: Loss of power: The engine may lose power or have difficulty reaching maximum power. Warning lights may come on: The engine warning light or other warning lights on the dashboard may come on. Abnormal noises: Noises may be heard coming from the engine compartment. Timing problems: In more severe cases, a displacement of the engine timing may occur. Displacement of the timing chain: In some cases, the defect may lead to a displacement of the timing chain.
