"What are the common issues with the M96 engine in the Cayman S?"

Question

Accepted Answer

The 2007 Porsche Cayman S actually uses the M97 engine (not M96), and here are the key issues to be aware of:

**Good News First:** The 2007 model has the final, larger IMS bearing with less than 1% failure rate - so the infamous IMS bearing issues that plagued earlier models are largely resolved.

**Main Concerns:**
1. **Bore Scoring** - This is the big one for the 3.4L M97.21 engine. Cylinder walls can wear excessively, typically between 30k-80k miles, causing oil consumption and performance loss
2. **RMS Seal Leaks** - Rear main seal leaks are common as these engines age
3. **Oil Consumption** - Higher than normal oil use can indicate developing issues
4. **Fuel Starvation** - Only really relevant if you plan to track the car hard

The 2007 Cayman S is generally considered more reliable than earlier M96-powered cars, but bore scoring is the primary thing to watch for. Regular oil analysis and monitoring consumption are your best prevention strategies.
