298-4570 Exhaust Manifold Gasket — Cat 320 420E

This exhaust manifold gasket is a crucial seal between the engine's exhaust manifold and the cylinder head, preventing exhaust gas leaks. It is manufactured to meet stringent OEM quality standards, providing a durable seal that resists high temperatures and pressures better than a worn or damaged gasket. Operators may notice a loud exhaust leak noise, reduced engine power, or black soot around the manifold connection when this gasket fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most common sign of a failing exhaust manifold gasket is an audible exhaust leak, often described as a ticking or puffing sound from the engine. If ignored, the leak can worsen, leading to reduced engine power, increased fuel consumption, and potentially damaging exhaust components. Continued leakage can also allow exhaust fumes into the operator's cabin.

Installation Tip

Thoroughly clean and inspect the mating surfaces of both the cylinder head and the exhaust manifold for flatness and damage before installing the new gasket. Ensure all manifold bolts are tightened in the correct sequence and to the specified torque.

Service Note

Inspect the exhaust manifold for cracks or warping, and check the manifold studs and nuts for damage or corrosion when replacing the gasket.
