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 the Billet Tappet Cover with an additional hardware kit to mount the ECM for your 98.5-02 VP44 configuration back onto the billet tappet cover. The hardware kit consists of stainless CNC machined standoffs, bolts and washers to mount your ECM neatly and securely back on the side of the engine.
