Used Porsche timing chain tensioner rail screw, OEM 99610517651, a genuine factory bolt for the M96/M97 engine family. This screw secures the tensioner rail that guides the timing chain. If this bolt loosens or fails, the rail can shift, causing chain rattle or even timing jump — a known issue on these flat-six engines. Also called the timing chain tensioner rail bolt. Direct fit for 2.5L through 3.4L naturally aspirated H6 applications in 911 and Boxster models.
