Our billet aluminum tappet cover works with VE, VP and P-Pump Cummins engines WITHOUT cutting or grinding! It features a built in oil retention system with internal baffles that helps keep the oil inside the crankcase where it belongs ! It utilizes an o-ring seal for a guarenteed leak free install instead of messy silicone or the OEM seal. If you are looking for a nice top of the line tappet cover for your current build or replacing a leaking cover , this is sure to get you fixed up ! We also offer a hardware kit to mount the ECM for your 98.5-02 VP44 configuration back onto the billet tappet cover.
