In the timing case, the guide rail sets the path the chain follows between the crankshaft and camshaft sprockets. It works together with the tensioner to control chain slack and vibration. The guide's plastic wear surface slowly wears down over time. As it wears, the chain develops slack and can produce the rattle known as chain slap, which is most noticeable at startup or idle. BMW gives the weight as 127 g, and this part is made in Germany.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eBMW calls this part Guide rail. Removing the timing cover on an N63 or S63 is a long, involved job. For that reason, any guide that shows wear should be replaced while the cover is already off, rather than reused. BMW's parts data shows production starting in July 2008. It is sold individually, as one piece.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Original BMW Parts)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-31-7-574-397\u003c\/li\u003e\n\u003cli\u003eBMW part name: Guide rail\u003c\/li\u003e\n\u003cli\u003ePosition: lower timing chain guide\u003c\/li\u003e\n\u003cli\u003eWeight: 127 g (0.3 lb)\u003c\/li\u003e\n\u003cli\u003eProduction start: July 2008\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Germany\u003c\/li\u003e\n\u003cli\u003eSold as: one piece\u003c\/li\u003e\n\u003cli\u003eWarranty: 24-month parts warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation \u0026amp; Tuning Notes\u003c\/h3\u003e\u003cp\u003eIf the timing cover is off for any reason, inspect every timing chain guide.
