S54 Upper Chain Guide

S54 Upper Chain Guide

Regular price $44.00 Sale

It's a good idea to check your upper chain guide rail (next to the chain tensioner) when removing the vanos as it makes it much easier to replace once the vanos is out of the way. These small chain guides are known to wear over time and can cause some chain noise (sometimes confused for vanos rattle) at low RPM, and if left unchecked it can eventually crack or break potentially causing engine damage. Kit includes replacement crush washer (07119963342).
