Exhaust Manifold Gasket – Honda Accord VII / Civic VII-VIII / CR-V II-III / FR-V / Integra DC5 / Stream – Elring 270.360

Elring 270.360 is an exhaust manifold gasket designed for Honda K-series engines, covering both K20 and K24 variants. The gasket sits between the exhaust manifold and the cylinder head, sealing the joint and preventing exhaust gases from escaping into the engine bay.

Elring is a well-established German manufacturer of gaskets and sealing components, supplying many OEM production lines worldwide. The 270.360 gasket is made from materials resistant to high temperature and exhaust pressure, ensuring long service life even in high-performance applications such as the Type R or Integra DC5 Type-R.

When to Replace the Exhaust Manifold Gasket?

A damaged or burnt-out exhaust manifold gasket typically presents with the following symptoms:

• Metallic ticking or tapping noise when cold that fades as the engine warms up – a classic sign of a leak at the cylinder head joint.
• Smell of exhaust fumes in the engine bay or inside the cabin while driving.
• Soot deposits or discolouration around the manifold-to-head mating surface.
• Audible hissing or rushing sound from the exhaust, especially during cold starts.
• Increased engine noise – the car sounds noticeably louder than usual under load.

In high-performance K20 engines (EP3, DC5 Type-R) the gasket is under greater thermal stress and more prone to premature wear. Checking the gasket condition at every service interval is good practice.

Installation and Service Tips

• Before fitting, thoroughly clean both mating surfaces on the manifold and the cylinder head – remove all traces of the old gasket, corrosion and carbon deposits. Surfaces must be flat and free of contamination.
• Check the manifold flange for warping. A warped flange will not seal reliably even with a new gasket – if in doubt, have the flange resurfaced or replace the manifold.
• Tighten the manifold bolts to Honda's specified torque, working in a cross pattern and in stages – avoid tightening one side at a time, as this can distort the flange.
• It is advisable to replace the manifold bolts at the same time – they operate at extreme temperatures and are prone to corrosion, often making it impossible to re-torque them reliably after removal.
• After starting the engine, check for leaks both when cold and once the engine has reached operating temperature.

FAQ – Frequently Asked Questions about the Honda Exhaust Manifold Gasket

Is Elring 270.360 a genuine Honda part?
No – Elring is an independent manufacturer of sealing components that supplies many OEM production lines. The 270.360 gasket is produced to Honda's technical specification and is a direct replacement for the original catalogue numbers listed above.

Does this gasket fit all K20 and K24 engines?
It fits the K-series engines listed in the compatibility table above. Always verify your engine code before ordering.

Do I need to replace the manifold when replacing the gasket?
Not necessarily, provided the manifold is undamaged and not burnt through. However, always check the flange for flatness – a warped manifold will not seal properly even with a new gasket.

Can the manifold bolts be reused?
Generally not recommended. Manifold bolts operate under extreme heat cycles and are highly susceptible to corrosion. After removal they often cannot be torqued to the correct value safely. Replacing the bolts while the manifold is off is considered best practice.

Can a leaking exhaust manifold gasket affect emissions test results?
Yes. A leak upstream of the lambda sensor can interfere with its readings and cause incorrect fuelling corrections, which has a negative impact on both engine performance and exhaust emissions measured during an MOT or roadworthiness inspection.
