Porsche 911 engines, especially older models, are prone to oil leaks due to worn gaskets, seals, or oil cooler problems.

The Intermediate Shaft (IMS) bearing is a well-known weak point in 996 and early 997 models, leading to catastrophic engine failures if not addressed.

These can occur due to aging coolant hoses, radiators, or water pump failures.

This is another common issue, leading to oil leaks between the engine and transmission.

The seals can degrade over time, leading to oil leaks into the spark plug wells.

Over time, the timing chain tensioners can fail, leading to improper timing and potential engine damage.

Problems with the variable valve timing system can lead to poor performance and increased fuel consumption.

Dirty or failing fuel injectors can cause misfires, rough idling, and poor acceleration.

A faulty MAF sensor can lead to poor engine performance and reduced fuel efficiency.

The exhaust components, including the muffler and catalytic converters, can corrode over time, leading to leaks and reduced performance.

The 2004 Porsche 911 is known for oil leaks, particularly from the rear main seal and the intermediate shaft (IMS) bearing.
