In short, a sealed, ball race bearing is used to support the flywheel end of the intermediate shaft. Over time, the grease in the bearing can dry-out - often aided by excessive running temperatures as some of the bearings are a very tight fit in the casing due to production tolerances. As the bearing is sealed, oil from the engine can't normally enter the housing (although it sometimes does, with the effect that the bearings go on 'forever' ) and the bearing eventually breaks-up leading to catastrophic failure. It appears that the main reason for the failures - the lack of lubrication as the bearing ages - has never been correctly addressed by Porsche. What Porsche has done is re-spec the bearing several times - single and double row bearings have been used, in several different load ratings. A small number of engineering shops, have managed to redesign the bearing so it receives plenty of engine oil to both lubricate and cool it - this seems to have effected a cure. Such modified engines (that often have other modifications to the cooling system and cylinder bores) are greatly prized and seem to be more-or-less bullet-proof. Bear in mind that the number of failures appears to only be a very small percentage of the total number of engines out there. The old adage that bad news gets discussed ad infinitum on forums, whilst good news never gets a mention, is probably very true where these failures are concerned.
The Porsche Scheduled Maintenance Plan allows you to manage your factory recommended scheduled maintenance services through the convenience of prepayment. How does it work? In establishing scheduled maintenance requirements for Porsche vehicles, our engineers in Germany determined the checks and service operations necessary to keep your Porsche running in optimal condition. The Porsche Scheduled Maintenance Plan covers each of these critical items for periods of 3 years/30,000 miles, 4 year/40,000 miles or 5 years/50,000 miles, depending upon which term best suits your needs. The Porsche Scheduled Maintenance Plan covers the regularly scheduled maintenance visits as specified in your vehicle鈥檚 published maintenance booklet, for time and/or mileage period purchased. All work will be performed at your authorized Porsche dealer by Factory-trained technicians using Genuine Porsche Parts. 2010, that has been in service less than 12 months, with less than 12,000 miles and has not had its first scheduled maintenance performed yet.

The Porsche 991 came to the market and was a big step up from the 997 chassis in terms of ergonomics, torsional rigidity, and even curb weight. The 991 Carrera S uses steel for the structure of the car, and aluminum for the doors, fenders, roof, and trunklid. All in, it tilts the scales at 3,120 lbs. Performance is excellent with the Carrera S and PDK combo. 0-60 comes up in just 3.9 seconds and rips off a 录 mile at 12.0 @116.5mph. It will handily dispose of most other cars on any back road. The car here was delivered in Carrara White over Agate Leather. It is a stunning color combination in person, and was unique to the 2012 991 offering. Ordered with factory Sport Seats (heated and cooled), Sport Chrono, Light Design, Entry & Drive, Porsche Sport Exhaust (PSE), Sunroof, and so much more. Please see the full details in the photographs. The condition of this two-owner car is better than expected with just over 32,000 miles - like new. The paint is factory fresh on all panels, and no blemishes on the interior, nor scrapes on any wheel - a truly pampered example. Even the undercarriage and suspension look new. Mechanically the car is perfect - it has been back to the original selling dealership for all service. Service records and stamps are present. This 991 chassis Porsche Carrera S is offered for sale in near flawless condition, with all original books, manuals, and keys all present. No excuses on this one - in the rare launch year only color combo!
