BMW 323Ci Oil Pumps

Since 1921, Cloyes has been the trusted leader in automotive timing systems. In some applications, the engine oil pump chain can be a critical component or adjacent to the engine’s timing system. Available as stand-alone chains or in complete kits, Cloyes oil pump chains are manufactured from premium materials, heat-treated, pre-stressed and engineered for a perfect chain to sprocket tooth fit, delivering quiet operation, durability, and performance you can count on.
