Intake Manifold Gasket for Caterpillar 3406 Engines

The intake manifold gasket plays a critical role in sealing the joint between the intake manifold and the cylinder head on your Caterpillar 3406 engine. Each engine requires six intake gaskets to ensure proper sealing across all ports. A worn or damaged intake gasket can lead to unmetered air entering the system, reduced efficiency, or increased emissions.

At Diesel Pro Power, we supply premium aftermarket intake manifold gaskets designed to meet or exceed Caterpillar’s performance standards. These gaskets are built from durable, heat-resistant materials to withstand the extreme conditions of heavy-duty diesel operation. Proper sealing is essential for maintaining compression and ensuring that your fuel-air mixture performs at maximum efficiency.

• Fitment: Caterpillar 3406 engines

• Quantity Required: Six per engine

• Construction: Heat- and pressure-resistant materials for long service life

• Performance Impact: Prevents air leaks, maintains optimal fuel-air ratio, and protects against power loss

Replacing intake manifold gaskets during routine maintenance or engine rebuilds ensures that your 3406 operates at peak performance. Many operators choose to install new gaskets whenever the intake manifold is removed, avoiding future downtime and ensuring reliable sealing.

Exhaust Manifold Gasket for Caterpillar Engines

The exhaust manifold gasket is designed to create a secure, leak-free connection between the exhaust manifold and the engine block. For the Caterpillar 3406, this component is vital to maintaining exhaust flow and ensuring that gases are directed through the turbocharger or exhaust system efficiently.

Exhaust leaks at the manifold not only reduce engine performance but can also expose operators to harmful exhaust gases, increase noise levels, and contribute to turbocharger inefficiency. Diesel Pro Power’s premium aftermarket exhaust manifold gaskets provide a robust seal designed to resist high heat cycles, vibration, and pressure.

• Fitment: Caterpillar 3406 engines

• Placement: Between exhaust manifold and engine block

• Construction: Multi-layered, heat-resistant material for durability

• Performance Impact: Prevents exhaust leaks, protects turbocharger performance, reduces noise, and maintains emissions control

Replacing exhaust manifold gaskets during engine overhauls or when any signs of leakage appear is critical to long-term performance. Symptoms of a failing gasket may include visible soot deposits near the manifold joint, a ticking sound under load, or reduced turbo efficiency.
