Parts for your 2010 Honda Elysion-Manifold gasket

2010 Honda Elysion manifold gasket — what it does and when to replace it

Referencing technical sources including the Honda Elysion factory service manual (2009–2012 coverage), Honda’s electronic parts catalogue for RR1–RR6 chassis, and major gasket catalogues (Mahle, Victor Reinz, Fel‑Pro), the 2010 Honda Elysion absolutely uses manifold gaskets. Both the 2.4‑litre K24A inline‑four and the J‑series V6 variants have intake manifold gaskets and exhaust manifold gaskets, with additional related seals such as throttle body and EGR gaskets.

On this Elysion, the manifold gaskets are there to keep things sealed and running sweet. The intake manifold gasket maintains proper vacuum and airflow so the ECU’s fueling stays on point, stopping unmetered air from sneaking in and causing lean running or rough idle. The exhaust manifold gasket keeps hot gases contained as they leave the head, protecting nearby components, stabilising oxygen sensor readings, and cutting down on noise and fumes under the bonnet.

• Common clues of an intake leak: hunting or high idle, a hissing sound, poor fuel economy, or codes like P0171/P0174 (system too lean).
• Common clues of an exhaust leak: ticking on cold start, sooty marks around the flange, exhaust smell in the cabin, or slow O2 sensor warm‑up.

Replacement isn’t a set‑interval service, gaskets are renewed when they leak or whenever the manifold is removed. Best practice on the 2010 Honda Elysion is to fit quality OEM‑spec gaskets, clean the mating faces thoroughly (no gouging with a scraper), and torque fasteners to factory specs in the correct sequence. Avoid extra sealant unless the service manual calls for it at specific joints. For exhaust work, pre‑soak fasteners, and consider new studs and copper‑coated nuts—years of heat cycles can make old hardware cranky. On intake jobs, inspect PCV hoses, the throttle body gasket, and any EGR or coolant passage seals while you’re in there.

After the job, a quick smoke test helps confirm there are no sneaky intake leaks. Clear fuel trims with a scan tool, let it relearn, and take a decent test drive. Look and listen for any fresh ticks or whiffs under the bonnet. Done right, the Elysion’s manifold gaskets should go many more kilometres without drama.

Popular questions

Does the 2010 Honda Elysion have both intake and exhaust manifold gaskets?

Yes. Technical references for the K24A four‑cylinder and J‑series V6 engines show dedicated intake manifold gaskets and exhaust manifold gaskets, plus related seals like the throttle body gasket. They’re standard fitment and essential for correct sealing and engine management.

How can someone tell if a manifold gasket is leaking on an Elysion?

Intake leaks often show up as a rough or high idle, a hissing sound, poor fuel economy, or lean codes (P0171/P0174). Exhaust leaks tend to tick on cold start, leave sooty marks near the flange, and can push exhaust smell into the cabin. A smoke test or careful listening under the bonnet helps confirm it.

Should the gaskets be replaced every time the manifold is removed?

That’s the smart move. While some multi‑layer steel gaskets survive a second use, Honda service practice is to renew manifold gaskets whenever they’re disturbed. Clean the faces, follow the torque pattern, and don’t add sealant unless the manual specifically calls for it.
