Tappet Cover w/ Oil Separator

Upgrade or replace a leaking factory tappet cover on your Cummins engine with the G&R Diesel Billet Aluminum Tappet Cover with Oil Separator. Designed for VE, VP, and P-Pump applications, this premium cover delivers superior sealing, improved oil control, and a clean, professional appearance for both street and performance builds.

Premium Construction & Materials

CNC-machined from high-quality 6061 aircraft-grade billet aluminum, this tappet cover offers exceptional strength, corrosion resistance, and long-term durability. It features a beautiful CNC-machined finish and includes all stainless steel hardware for a secure, rust-resistant installation. A main sealing O-ring replaces the messy factory gasket or silicone, providing a reliable, leak-free seal to the engine block.

Key Features & Benefits

• Universal Cummins Compatibility: Works with VE, VP44, and P-Pump Cummins engines without requiring cutting or grinding.
• Integrated Oil Separator: Features a built-in oil catch can with an internal baffle system that helps retain oil in the crankcase where it belongs, reducing oil mist and mess.
• Superior Sealing: Utilizes a precision O-ring seal for the main cover-to-block interface (and additional O-ring for the CCV can), eliminating common factory leak points.
• Complete Hardware Kit: Includes the main sealing O-ring, 6 stainless socket head bolts for the cover, a CNC-machined CCV (crankcase vent) can, O-ring for the can, and 4 stainless socket head bolts to secure the can.
• Clean, Professional Appearance: The machined billet finish enhances engine bay aesthetics while delivering functional improvements.
• Garage-Friendly Installation: Designed for straightforward installation with common tools when proper procedures are followed.

Recommended Accessories

We strongly recommend pairing this cover with the G&R Diesel Stainless Steel Vent Hose Kit for a cleaner, more professional installation and optimal crankcase ventilation.

Note for VP44 Applications (1998.5–2002): An optional ECM Mounting Hardware Kit is available to relocate or remount the ECM cleanly when using this billet cover. (GRD59CM3010)

Applications

• Cummins engines equipped with VE, VP44, or P-Pump injection systems (primarily 1989–2002 5.9L applications)
