On the 2006-2016 Porsche Cayman, the Cayman M97 and MA1 flat-six engines develop bore scoring on cylinders 1 and 6, identical to the pattern seen in the 911 and Boxster. The Cayman GT4 with its 3.8L 911-derived engine is also affected. Oil starvation at the cylinder walls during cold starts is the primary cause.

This issue also affects: Acura MDX, Acura TL, Audi Q7

Common Symptoms

Increasing oil consumption
Blue smoke on cold start
Misfires
Low compression on affected cylinders
Rough idle when cold

How to Fix

Engine rebuild with iron cylinder sleeves (Nickies) or engine replacement. Regular borescope inspections can detect scoring before it becomes catastrophic. Allow full warm-up before spirited driving.

On the 2006-2016 Porsche Cayman, the AC compressor on the Cayman fails prematurely, often due to clutch bearing wear or internal seal failure. The mid-engine layout subjects the AC system to higher ambient temperatures. When the compressor clutch fails, it can throw the serpentine belt and disable all accessories.

This issue also affects: Acura TSX, Chevrolet Malibu, Fiat 500

Common Symptoms

AC blowing warm air
Clicking or grinding noise when AC engages
Serpentine belt squealing
AC clutch not engaging
Burning rubber smell from accessory belt area

How to Fix

Replace the AC compressor and receiver/drier. Flush the AC system of any debris from the failed compressor. Replace the expansion valve as preventive maintenance. Ensure proper refrigerant charge after repair.
