1990 Porsche Carrera problems

Common 1990 Porsche Carrera problems

The Porsche Carrera 1990, also known as the 964, is known for being relatively reliable compared to other generations of the 911. However, there are some common problems that owners have reported.

One of the most well-known problems with the 964 is oil leaks, which can come from various sources such as the rear main seal, valve covers, spark plug seals, and turbo oil supply line seals. These leaks can be caused by wear and tear on the seals and gaskets, and can lead to a messy engine bay and potential engine damage if not addressed.

Another common issue with the 964 is worn suspension bushings. Over time, the rubber bushings that connect the suspension components to the chassis can wear out, leading to a less precise and comfortable ride. Replacing these bushings can be a time-consuming and expensive process, but it can greatly improve the handling and comfort of the car.

Additionally, some 964 models may experience issues with the distributor belt, which can wear out and cause misfiring or stalling. This issue is more common in the early models of the 964, and can be addressed by replacing the belt and tensioner.

Another potential issue with the 964 is failed dual-mass flywheels. These flywheels are designed to reduce vibration and improve smoothness, but they can wear out over time and cause issues with the clutch and transmission. Replacing a failed dual-mass flywheel can be a costly repair, but it is necessary to ensure the proper function of the clutch and transmission.

Finally, some 964 models may experience issues with the ABS brakes, which were introduced in this generation. These issues can include leaking brake lines, faulty sensors, and other electrical problems. Regular maintenance and inspection of the ABS system can help prevent these issues and ensure safe and reliable braking.

In summary, the Porsche Carrera 1990, or 964, is generally a reliable car, but like any vehicle, it can experience common problems such as oil leaks, worn suspension bushings, distributor belt issues, failed dual-mass flywheels, and ABS brake problems. Regular maintenance and inspection can help prevent these issues and ensure the longevity and reliability of the car.
