The Porsche 911 with the 3.4-liter engine, particularly in the 997 generation, is known to experience issues such as IMS (Intermediate Shaft) bearing failure, which can lead to catastrophic engine damage if not addressed. Additionally, some owners report problems with oil leaks and coolant issues. Regular maintenance and early intervention can mitigate some of these risks, but potential buyers should be aware of the engine's vulnerabilities.
