Timing Chain Guide Rail ORIGINAL PORSCHE Cayenne 9PA 955 4.5 94810506821 Very good build quality Description: The timing chain with sprockets, guide rails, and tensioner forms the most important connection between shafts in the engine. It ensures the reliable control of the valves. Failure of any of these components can result in catastrophic engine damage. Mechanical/hydraulic chain tensioners should be regularly serviced to ensure the timing chain is always correctly tensioned. Components such as a tensioner rail, sprocket, or the chain itself should be replaced at the first sign of wear. This is also noticeable by rattling engine noises. These components are replaced as part of regular maintenance anyway. We also offer high-quality complete sets in our product range. Brand Information: The Porsche brand is well-known to all of us.
