Secured Oil Pump Nut Kit for BMW 6-Cylinder

The nut holding the drive sprocket on your oil pump can become loose over time.  We have personally seen this on more than a couple M3 motors, but caught the problem before the nut became too loose.  Others have not had such luck.There are countless stories of oil pump nuts coming loose and causing a no oil pressure situation costing thousands in repairs or replacement.This oil pump nut has a hole EDM'd (Electrical Discharge Machined) on the flat to allow it to be safety wired to the oil pump sprocket. The kit includes one oil pump nut and a longer than needed length of safety wire to secure it.  It's a small price to pay for peace of mind.
