No, the poll numbers above. The poll numbers above used to be separated into 997.1 and 997.2. Someone then combined the 2 models which diluted the IMS failure percentage. Seemed like the 997.1 failure rate was in mid teens before the combined the 997.1 and the 997.2 numbers.

Sorry to jump in late here but it seems like the thread to look for input.
I am looking at a 2006 C2S and from what I read on here this has the larger bearing and moved to center of the block? No mid-year adjustment to worry about? It has just under 32 miles, Sport Chrono,6mt, PSE, factory short shift, sport seats. Fairly basic. I drove it today and it was tight and seemed to run good. Love the short shifter and sport exhaust! Guy is asking just under $43k. Seems high to me?

Nope, not here!

Hi - yes the 2006 has the larger improved bearing with very, very low failure rate. However not sure about the reference to "moved to center of the block". Both large and small bearings are in the same place on the IMS.

For those miles and spec sounds like a very good price. Looks like you are doing your homework but make sure to get a proper PPI. I recommend to everyone to get the oil filter pulled during the PPI and check for any debris.

Besides regular maintenance schedule, plugs, etc, you have a couple standard wear items on the 997.1 that you will need to take care of sooner or later: coolant expansion tank replacement, starter/alternator cable replacement, possibly a leaky RMS seal but thats easy to replace when you replace the clutch. None are serious, but can add up if you intend to take to your local dealer for service. If you have a good local mechanic each would cost $500-1k, 3x that at the dealer. If you are mechanically inclined the parts are less than $100.

The other thing you want to watch out for on the 997.1 is "bore scoring". There are 30-40 cars that have reported it on this forum. Its most always found in cold weather cars from the midwest or Canada and the theory is they weren't properly warmed up and/or had high amounts of ethenol in the winter fuel which scored the scores leading to excessive oil consumption and eventually "piston slap". If its a warm weather car you typically have nothing to worry about but should inquiry about oil usage and spend an extra couple hundred bucks to have the bores scoped during the PPI. Then be happy and enjoy a phenomenal car.

2005 C2S, 75,000 miles, probably m96. Failure at 75,000 miles. No prior indications, including at oil change 1000 miles previously. No prior problems. Water pump failed 2 weeks prior, but no overheating.

Motorainier

I agree. After being told by several well respected people I shouldn't have a problem mine failed with NO warning. Oil was checked 1,200 miles previously, and 4,000 miles before that, with nothing found.

Sorry to hear that. An S should be an M97 motor. Can you provide the build date of your car from the body label and your engine serial # (on the block visible from underneath on the driver's side). You likely had an early 05 build with the same smaller bearing from the M96 motor.

Also, when you changed the water pump, we're any pieces of the impeller fins missing?

Motorainier

There shop said there were no pieces missing from the fins. I do trust them, as they're a long time Porsche shop with a great reputation. I can't check the motor, my car is sitting in the shop while I sort through my options (sell, rebuild, rebuild and modify).
