Ever have an oil pump sprocket retaining nut back off and lose oil pressure? How about shearing off 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 the most unsuspecting BMW enthusiast more than you might think. This kit is very popular for a reason; it eliminates all failures modes permanently while retaining serviceability. Some people believe it is enough to weld the OEM bolt on, or use a special nut, 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 oil pump issue effects 100% stock and modified motors and we get calls and emails with these failures several times a month. An oil pan baffle is not enough, do NOT be the victim this common failure! This kit is the best solution on the planet addressing 100% of the issues. UPGRADE your oil pump with a VAC Oil Pump Upgrade Kit and safeguard yourself against silly yet extremely costly oil pump failures. VAC Spec E46 Oil Pump Upgrade Kit includes:
VAC Tech Notes:Kit install is simple but requires a press. If you would like, you can also ship your oil pump to us and have our experienced machine shop staff recondition and install your new VAC kit for a $100 fee. You will receive your upgraded oil pump ready to bolt in.
