Timing issues can be detrimental to the longevity of your BMW. If you're getting high in mileage or suspect a timing issue, it's likely time for a timing service. We have everything you need from tensioners to guides here at Turner Motorsport.
Over time, timing chains can begin to stretch and tensioners can wear out or seize. This leads to slack in the chain, which can cause the chain to slip. A slipping chain is often a death sentence for N55/S55 engines as these are interference engines, resulting in damaged pistons, valves, and other sensitive engine components. If your engine has higher mileage, it is worth it to replace your chain and tensioner for peace of mind. We also recommend picking up timing chain guides as the plastic guides used by BMW are known to wear down and become weak.
