• Complete Engine Overhaul Solution
  This comprehensive gasket kit includes every seal and gasket needed for a complete engine rebuild. 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 5281440) designed specifically for the QSF2.8'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 modern Tier 4 diesel engines.

• Front Crankshaft Seal Included
  The kit includes the front crankshaft oil seal (OEM 3695721F), a critical component that prevents oil leakage from the timing gear case. This seal is specifically designed for the QSF2.8's front crankshaft journal.

• Complete Valve Train Sealing
  Includes valve cover gaskets (OEM 5613915L) 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 manifold gaskets (OEM 4983019) that seal the intake manifold to the cylinder head, ensuring proper air-fuel mixture delivery. Exhaust manifold gaskets are also included to prevent exhaust gas leaks.

• All Necessary O-Rings and Seals
  The kit contains all required O-rings including the sump plug O-ring (OEM 5294118) and D-ring seals (OEM 4957784) for various engine plugs and sensors. These small but critical components prevent oil and coolant leaks at multiple points throughout the engine.

• 100% Complete – Every gasket and seal required for a full engine overhaul is included in one convenient kit.

• OEM Standard – Manufactured to meet or exceed original Cum mins specifications in ISO-certified facilities.

• Warranty – 12-month warranty against manufacturing defects.

• Global Shipping – Fast DHL, FedEx, UPS shipping available from multiple warehouses.

• Expert Support – Need help identifying the correct kit for your engine? Send us your engine serial number (ESN) – Cum mins ESN can be found on the engine data plate, typically located on the rocker cover or side of the gear housing.

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 QSF2.8 engine, follow these critical guidelines:

1. Always verify the correct gasket kit based on engine serial number, as QSF2.8 engines may have different gasket specifications depending on build date and Tier level.

2. The oil pan gasket (5281440) requires proper alignment during installation to prevent leaks.

3. Cylinder head bolts must be replaced according to factory specifications – do not reuse old head bolts.

4. Clean all mating surfaces thoroughly before installation to ensure proper sealing.

5. Follow factory torque specifications and tightening sequences for all components.

6. 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.
