Ever have an oil pump sprocket retaining nut back off and lose oil pressure? How about shearing of the oil pump shaft with the sprocket and nut still attached? Chances are you lost that engine. We at VAC Motorsports hear this all the time and it happens to most unsuspecting BMW enthusiast more than you might think.
This kit is very popular for a reason; it eliminates all failure modes permanently while retaining serviceability.
Some people believe it is enough to weld the OEM bolt on, or use a special nut and/or safety wire, however in these cases this does
not solve the shearing of the shaft (completely off!) and in some cases can make things worse.
This effects 100% stock and modified motors and we get call and emails with these failures several times a month on all types of BMWs, especially ones that see track time.
This kit is the best solution on the planet addressing 100% of the issues.
