Efficiency has always been at the heart of the Porsche engine design, and any part that threatens this efficiency can greatly reduce the performance of your vehicle. After sixty thousand miles, the Porsche timing belt/timing chain often begins to show signs of wear. Either the belt stretches, or the gears and chain start to suffer from metal fatigue. Both cause the engine to start to suffer from the symptoms of sloppy timing. Inspection of the Porsche timing belt/timing chain at the factory recommended intervals helps to ensure proper operation of the intake, combustion, and exhaust operations of the engine. It may also avoid costly damage, because when the Porsche timing belt/timing chain fails, certain engines may suffer from secondary damage caused by the failure, such as bent valves. If this happens, the entire engine may have to be remanufactured, turning a repair that could have cost a few hundred dollars, into one that may cost a few thousand. When the Porsche timing belt/timing chain is replaced, any gears and pulleys in the system should also be replaced to avoid shortening the lifespan of the new part. In addition, the water pump is often located near the Porsche timing belt/timing chain, and has a similar life expectancy, so replacing it at the same time will save a large amount of labor in the future.
