Parts for your 2009 Honda Elysion-Exhaust gasket

2009 Honda Elysion exhaust gasket: what it does and when to replace it

Yes, the 2009 Honda Elysion uses exhaust gaskets. Honda’s Electronic Parts Catalogue for the RR1–RR3 Elysion platform and engine service information for the K24A (2.4-litre) and J30A (3.0-litre V6) engines show multiple exhaust sealing points: a cylinder-head to exhaust-manifold gasket, a manifold-to-front pipe “donut” gasket with spring-bolted joint, and flat flange gaskets further down the system. Honda service procedures specify replacing disturbed exhaust gaskets during removal/refit to ensure correct sealing.

The exhaust gasket on a 2009 Honda Elysion is a small part with a big job. It seals the joints where hot gases pass from the engine to the tailpipe, keeping the system quiet, fume-free, and accurate for the oxygen sensors. On these Elysions, expect a metal multi-layer manifold gasket at the head, a crush-style donut where the manifold/front pipe join, and flat gaskets at mid and rear flanges. When they’re tired or pinched, the result is that tell-tale ticking on cold start, an exhaust smell around the cabin, and sometimes a CEL due to skewed O2 sensor readings and fuel trims.

As part of routine servicing, a quick check of the exhaust joints is worth it, especially on higher‑kilometre Elysions. Look for sooty deposits at flanges, listen for a sharp tick that quietens as it warms up, and pay attention to any sudden change in exhaust note. If the joint uses a spring-bolt arrangement (common at the donut), make sure the springs and bolts aren’t seized or weak—replacing the hardware with the gasket often restores proper clamp load.

• Replace disturbed gaskets: manifold and donut gaskets are designed to crush once—don’t reuse.
• Clean, flat faces: remove old residue and rust
