Industrial Injection PDM-08153 Billet Tappet Cover 24-Valve Cummins No Breather

The Industrial Injection PDM-08153 Billet Tappet Cover is a performance-grade direct replacement for the factory tappet cover on the 24-valve Cummins diesel engine. Machined from a single piece of billet aluminum, this cover delivers superior strength and a clean, finished appearance compared to the original stamped steel unit that is notorious for warping, leaking, and deteriorating over time.

The factory rubber seal and stamped steel cover design is a well-known weak point on the 24-valve Cummins, especially on higher-mileage or modified engines. Industrial Injection's billet aluminum solution eliminates that failure point entirely, providing a rigid, leak-resistant sealing surface when paired with high-temp RTV silicone sealant (not included). All required mounting hardware is included for a complete installation.

Key Features:

• One-piece billet aluminum construction — superior rigidity and corrosion resistance versus OEM stamped steel
• Direct replacement fitment — no modifications required, installs with included hardware
• Designed for VP44 injection pump applications — purpose-built for the 24-valve platform
• Eliminates factory rubber seal — removes the leak-prone OEM gasket design
• No-breather design — clean, sealed cover without an integrated breather port
• All mounting hardware included — complete bolt kit provided
• High-temp RTV required for installation — not included

Whether you're refreshing a daily driver or building a high-output performance engine, the Industrial Injection PDM-08153 is a durable, long-term fix that also improves the visual appeal of your engine bay.
