About the 911 Carrera

The 996 Carrera (1998-2004) was the first water-cooled 911, representing Porsche's most significant engineering change since 1963. The M96 3.4-litre engine (later 3.6-litre) offered more power and refinement than the air-cooled cars. While initially controversial among purists, the 996 is now appreciated on its own merits. Values have risen as the 996's driving qualities and relative affordability attract enthusiasts.

Known Issues to Watch For

Engine: IMS (Intermediate Shaft) bearing failure is the known 996 issue - can cause catastrophic engine damage. Single-row bearing (1999-2000) higher risk; dual-row (2000-2005) better but not immune. IMS bearing replacement recommended. RMS (Rear Main Seal) leaks common. Bore scoring on some engines. Transmission: G96 6-speed generally reliable. Tiptronic can have issues. Cooling: Radiators crack. Expansion tanks fail. Electrics: Window regulators. PCM failures. Suspension: Control arm bushings. Brakes: Standard discs adequate. Body: Generally solid but check for accident damage.
