Fiat X/19 (Fiat=1972-82) (Bertone=1982-89)

Common faults with the Fiat X1/9 include:

- Oil leaks from between the camshaft carrier and cylinder head.
- Head gasket failure, particularly in 1300 engines.
- Overheating due to the engine's location and potential issues with the cooling system not being maintained properly.
- Electrical problems, as the wiring can degrade over time.

It's also important to check for coolant leaks and inspect the radiator for leaks to prevent overheating⁵.
