Original BMW Upper Left Timing Chain Slide Rail for BMW N63 and S63 V8 550i, 650i, 750i, X5, and X6 (2008–2014)

Original BMW slide rail 11-31-7-565-242 is the timing chain guide at the top left of the timing set on BMW N63 and S63 V8 engines, guiding the chain on its path around the crankshaft and camshaft sprockets in the 550i, 650i, 750i, Alpina B7, X5, and X6. BMW calls it "Slide rail," and production started in July 2008. It is made in Germany and sold as a single piece. As the chain slides across the rail face, the surface wears, and a worn guide is a likely cause of loud rattling or clattering when the engine is running.

A timing chain guide holds the chain in line and limits its movement and vibration, working with the tensioner to keep correct chain tension. A severely worn or broken guide can let the chain slip, which can show up as misfires, stalling, or hard starting. This guide is found on the top left side of the timing set, so confirm that position before ordering. This guide should be replaced whenever a new timing chain is installed.
