Lot WP0-622451: 2002 Porsche Boxster

The M96 engine in your 2002 Boxster has several well-documented issues that you should be aware of. Here are the most common problems, ranked by severity and likelihood for your low-mileage car:

1. IMS Bearing Failure (Most Critical)

This is the infamous issue that can cause catastrophic engine failure. The intermediate shaft bearing can fail without warning, sending debris throughout the engine. For your 2002 with only 18,888 miles, you’re in the danger zone - these bearings can fail due to age and lack of use, not just mileage. Replacement cost: $1,800-$3,500. If it hasn’t been done, this should be your first priority.

2. Cylinder Bore Scoring

This causes vertical scratches in the cylinder walls, leading to oil consumption, loss of compression, and eventually engine failure. Symptoms include excessive oil consumption and misfires. Your low mileage is actually protective here - bore scoring typically affects higher-mileage cars.

3. Air-Oil Separator (AOS) Failure

The AOS separates crankcase vapors from liquid oil. When it fails, it can cause engine vacuum issues, oil consumption, and in severe cases, hydrolock. This is a maintenance item that should be replaced preventively.

4. Water Pump Failure

These typically fail around 70-90k miles, so you’re still safe for now, but it’s something to plan for.

5. RMS (Rear Main Seal) Leaks

Common oil leak source, relatively inexpensive to fix.

My recommendation for your car: Given the ultra-low mileage and age, the IMS bearing replacement is absolutely critical - don’t wait. The FAQs on your listing show other buyers are asking about this too, which tells you everything you need to know about its importance.

Would you like me to help you find similar low-mileage Boxsters that have already had the IMS service done, or do you have questions about any of these specific issues?
