1989-1998 Cummins Billet Tappet Cover w/ Breather (PDM-08152)

Billet aluminum tappet cover with integrated crankcase breather for 1989-1998 Dodge 5.9L 12V Cummins engines. Replaces the factory stamped-steel cover and the rubber seal it relies on — a common nuisance leak on high-mileage 12V engines, especially after a P-pump upgrade where crankcase pressure climbs.

Machined from solid aluminum with a flat sealing surface designed to be sealed with high-temp RTV instead of the OE gasket. Built breather port relieves crankcase pressure cleanly — no oil seepage past the seal under load.

• Billet Aluminum Construction
• Built-In Crankcase Breather Port
• Eliminates Leak-Prone Factory Rubber Seal
• Common Upgrade for High-Pressure P-Pump Builds
• Part Number: PDM-08152

• Designed to be sealed with high-temp RTV (not included).
• Most beneficial on P-pump (1994-1998) builds where crankcase pressure runs higher. Bolts to VE-pump (1989-1993) engines too.
