2006 Porsche Cayman S Engine cooling Problems

“As I was accelerating for a merge, the car bucked and hesitated despite having my foot on the gas. I shifted gears and it was the same problem then there was an odd noise from the engine. I pulled off and the oil pressure warning light came on just as I stopped the engine. I had the car towed to the repair shop.”

“The engine experienced a cylinder failure in the #5 cylinder. The #5 piston 'clipped' a valve, the valve dropped into the cylinder, the piston impacted the valve and caused the #5 piston rod to break loose completely and punch a hole in the top of the engine core. There were also cracks in the #5 cylinder wall. I had to purchase a completely new engine from the manufacturer and have my local dealer install it. The final repair bill was $25,000.”

“The engine failed whilst taking part in a driving event at willow springs raceway. Oil starvation caused #6 conrod big-end bearing failure at approximately 4000rpm leading to internal destruction of the engine and an enormous plume of white smoke out through the exhaust.

“Motor failed unexpectedly while accelerating, causing loss of power and loss of control. Mechanic inspection says that it was not my fault, as the failure occurred at 3500 RPM and there was no stress that should cause failure. No sludge found in engine, oil changes done on time. Failure necessitates a completely new motor at a cost of $16,000. After investigation, it appears that complete motor failure between 40-50k miles on the 2006 Porsche Cayman S is fairly common.”
