My turn...

997.1 Carrera S (2005-2009)

New smaller intermidiate shaft bearing can still fail.

When enlarging the cylinders to 3.8 the water jackets surrounding the cylinder were reduced in size resulting in heated pistons scoring the cylinders until the cyl wall comes apart.

Water pump impeller blades come apart and since the blades are so freaking close to the block they can and have destroyed the block when they fail. Plastic impeller blades come apart also and when they do, pieces of the impeller get lodged in the water jacket causing the engine to over heat and can destroy the pistons and cylinders.

These engines run so hot because of the reduced size of the water jackets around the cylinders Porsche installed a temp gauge that doesn't rise above 175. I took my car out for a very hot spirited drive recently redlining shifts down shifting for several hours the oil gauge read 250 and my temp gauge was still sitting at 175!

Oil squirters you say, well the oil squirter only squirts the bottom of the piston. If they would have pointed the squirters toward the top of the piston where it was really needed there might not have been any D chunk problems.

Own this car??? Want it to last for awhile at least:

Change water pump every three years.

Change oil every 3 k miles Motul or Joe Gibb NO Mobil 1!!

Upgrade you chain ramps.

I'm not doing it. I just sold mine. Freaking time bomb car. And from Porsche no less. I'm going back to my slow 993.
