As a Porsche owner, you're well aware of the exceptional performance and engineering that goes into every vehicle. However, there's one potential issue that can lead to catastrophic engine damage: the IMS bearing.
The IMS bearing (Intermediate Shaft Bearing) is a critical component that supports the camshaft in Porsche's M96 and M97 engines. It's responsible for transmitting power from the crankshaft to the camshaft, ensuring proper timing of the engine's valves. Unfortunately, these bearings can be prone to failure, especially in early models.

To prevent the costly consequences of IMS bearing failure, Porsche owners should consider the following strategies:
Preventative IMS Bearing Replacement Costs | Authority |

$2,500 - $4,000 | Porsche Dealership |
$1,500 - $2,500 | Independent Porsche Mechanic |
"I had my 2001 Porsche 911 Carrera serviced regularly, but the IMS bearing still failed at 85,000 miles. The engine was completely destroyed, and I had to replace it at a cost of over $20,000. If I had known about the potential issue, I would have replaced the bearing as a preventive measure." - John, Porsche 911 owner
"I purchased a used 2004 Porsche Boxster and had the IMS bearing inspected during the pre-purchase inspection. It was in perfect condition, so I decided to drive it for a few months before replacing it. However, the bearing failed just 300 miles later, resulting in catastrophic engine damage. Thankfully, the car was under warranty, but the repair still cost me $6,000." - Sarah, Porsche Boxster owner
"My 2006 Porsche Cayman has over 150,000 miles, and the IMS bearing is still going strong. I credit this to regular maintenance, including annual oil changes and inspections. I also had the bearing replaced as a preventive measure at 100,000 miles." - Mark, Porsche Cayman owner
