Complete Engine Overhaul Solution
This comprehensive gasket kit includes every seal and gasket needed for a complete engine rebuild on the 3.9L 4BT engine platform. From the cylinder head to the oil pan, all mating surfaces are covered, eliminating the need to source individual components separately.
OEM-Spec Cylinder Head Gasket
The cylinder head gasket is manufactured to original equipment specifications, ensuring proper combustion sealing and compression. Available in MLS (Multi-Layer Steel) or high-grade graphite composite depending on engine application, providing excellent heat resistance and long-term durability under extreme operating conditions.
Precision-Fit Oil Pan Gasket
Includes the oil pan gasket (OEM 3929092) designed specifically for the 4BT's oil pan configuration. Ensures a leak-free seal between the oil pan and engine block, preventing oil leaks that can lead to engine damage.
High-Temperature Seal Materials
All seals exposed to high heat, such as turbocharger and exhaust manifold gaskets, are manufactured from high-temperature materials including Viton and multi-layer steel. These materials withstand the extreme temperatures generated by turbocharged diesel engines.
Front Crankshaft Seal Included
The kit includes the front crankshaft oil seal (OEM 3921378), a critical component that prevents oil leakage from the timing gear case. This seal is specifically designed for the 4BT's front crankshaft journal.
Complete Valve Train Sealing
Includes valve cover gaskets (OEM 3926045) that seal the rocker arm cover to the cylinder head. These gaskets are designed to withstand the pressures and temperatures of the valvetrain environment while preventing oil leaks.
Intake and Exhaust Manifold Gaskets
Features intake and exhaust manifold gaskets that seal the manifolds to the cylinder head, ensuring proper air-fuel mixture delivery and preventing exhaust gas leaks.
All Necessary O-Rings and Seals
The kit contains all required O-rings and seals for various engine plugs and sensors. These small but critical components prevent oil and coolant leaks at multiple points throughout the engine.

The cylinder head gasket is a critical component that seals the combustion chamber between the engine block and cylinder head. When installing a new gasket kit on a Cum mins 4BT engine, follow these critical guidelines:
Always verify the correct gasket kit based on engine serial number, as 4BT engines may have different gasket specifications depending on build date and configuration.
The oil pan gasket (3929092) requires proper alignment during installation to prevent leaks.
Cylinder head bolts must be torqued according to factory specifications in the correct sequence.
Clean all mating surfaces thoroughly before installation to ensure proper sealing.
Follow factory torque specifications and tightening sequences for all components.
Professional installation is recommended due to the precision required for proper sealing.
Warning: Improper installation can lead to coolant leaks, oil leaks, compression loss, and severe engine damage. Always verify proper torque specifications and tightening sequences.
