Leaking oil from seals or gaskets is common in high-performance engines like the Porsche 911, particularly around the valve covers and oil pan.

High-performance engines generate a lot of heat, which can strain the cooling system and lead to issues like coolant leaks or overheating.

If the engine is turbocharged, issues such as turbo lag, boost leaks, or turbo failure can be problematic, particularly in older or heavily used models.

Misfires can occur due to faulty spark plugs, ignition coils, or fuel injectors, affecting the engine's performance and smoothness.

Over time, the timing chain or belt can wear out, potentially causing engine timing issues that can lead to severe engine damage if not addressed.

Issues like clogged fuel injectors or a failing fuel pump can cause poor engine performance and reduced fuel efficiency.

Direct injection engines, like those found in many Porsche models, can suffer from carbon build-up on intake valves, leading to reduced performance and efficiency.

Modern engines rely heavily on sensors (e.g., oxygen sensors, MAF sensors) to regulate performance, and failure of these sensors can result in poor engine operation.

Problems like exhaust leaks or failure of catalytic converters can affect emissions and engine performance.

If equipped, problems with the VVT system can affect engine performance and efficiency, often indicated by a check engine light.
