Intake Manifold Gasket for Caterpillar 3406B Engines

The intake manifold gasket is a small but vital component in the Caterpillar 3406B engine. It seals the joint between the intake manifold and the cylinder head, ensuring that only metered air passes into the combustion chamber. The Caterpillar 3406B requires six intake gaskets per engine, with one fitted at each intake port.

Over time, exposure to high operating temperatures, vibration, and pressure changes can cause intake gaskets to wear out, crack, or lose sealing integrity. When this happens, operators may notice reduced engine efficiency, unusual noise during operation, or increased fuel consumption due to incorrect air-fuel ratios.

Diesel Pro Power provides premium aftermarket intake manifold gaskets specifically designed for Caterpillar 3406B applications. These gaskets are manufactured from high-quality, heat-resistant materials engineered to withstand heavy-duty cycles common in trucking, industrial, and marine applications.

• Fitment: Caterpillar 3406B engines

• Quantity Required: Six per engine

• Key Role: Maintains airtight seal between intake manifold and cylinder head

• Benefits: Preserves compression, ensures fuel efficiency, reduces the risk of unmetered air leaks

Routine replacement of intake manifold gaskets during maintenance or rebuilds prevents downtime and protects engine performance. Many operators replace these gaskets whenever the manifold is removed to guarantee a leak-free reinstallation.

Exhaust Manifold Gasket for Caterpillar 3406B Engines

The exhaust manifold gasket is another critical sealing component, located between the exhaust manifold and the engine block. In the Caterpillar 3406B, this gasket ensures that exhaust gases are properly routed through the manifold and into the turbocharger or exhaust system.

A failing exhaust manifold gasket can lead to dangerous exhaust leaks, loss of turbo efficiency, and excessive soot deposits in the engine bay. Operators may hear a ticking noise under load or notice reduced horsepower when the gasket no longer seals properly.

Diesel Pro Power’s premium aftermarket exhaust manifold gaskets are engineered to endure extreme heat cycles, high pressure, and constant vibration—conditions the Caterpillar 3406B encounters daily. By maintaining a tight seal, these gaskets prevent power loss, protect turbocharger efficiency, and help reduce harmful emissions.

• Fitment: Caterpillar 3406B engines

• Placement: Between exhaust manifold and engine block

• Material: Multi-layer, heat-resistant construction for durability

• Benefits: Prevents leaks, maintains turbo performance, protects operators from exposure to exhaust gases

Replacing exhaust manifold gaskets is essential during overhauls, turbo servicing, or whenever signs of leakage appear. A properly sealed exhaust system ensures smoother operation, quieter performance, and more efficient fuel burn.
