Parts for your 2014 Honda Accord-Exhaust gasket

2014 Honda Accord exhaust gasket — what it does and when to replace it

Based on Honda’s 2013–2017 Accord service manual procedures and the Honda electronic parts catalogue exploded views for the exhaust system, exhaust gaskets are indeed used on the 2014 Honda Accord. Both the 2.4L four-cylinder and the 3.5L V6 use crush or ring-style gaskets at exhaust pipe flanges, the V6 also uses manifold-to-head gaskets. Honda service literature specifies replacing these gaskets whenever the joint is disturbed, treating them as single‑use items to ensure a proper gas-tight seal.

On this Accord, the exhaust gasket’s job is simple but crucial: it seals the joints where sections of the exhaust bolt together, keeping hot gases inside the system and noise and fumes out of the cabin. Typical spots include the front pipe to catalytic converter, mid‑pipe to muffler, and on V6 models, between the exhaust manifolds and the cylinder heads. These gaskets are made to crush slightly when torqued, filling tiny imperfections in the flanges so there’s no leak path.

When servicing the exhaust on a 2014 Accord, it’s smart to plan on new gaskets any time a flange is undone. Reusing an old crush ring often leads to a tick at cold start, a hiss under load, or that sulfur smell sneaking into the cabin. Honda’s service guidance backs this up, calling for gasket replacement and even new spring bolts where applicable. A tidy approach under the bonnet and underbody pays off.

Handy tips for a tidy job:

• Clean mating faces with a Scotch‑Brite pad, don’t gouge the flanges.
• Use the correct OEM‑style gasket (flat, multi‑layer steel, or donut) for the joint type.
• Tighten evenly in a criss‑cross pattern to the specified torque, let spring bolts do the clamping.
• Replace tired hangers so the system doesn’t stress the new seal.
• A dab of high‑temp anti‑seize on studs helps the next service, but keep it off gasket faces.

If there’s a chuffing sound, soot marks at a flange, or a whiff of exhaust near the front of the car, the gasket may be on the way out. Left alone, leaks can cook nearby components and trigger O2 sensor or catalyst efficiency faults. For most owners across Australia and New Zealand, exhaust gaskets are a “replace when disturbed” item rather than a scheduled interval, but any WOF/roadworthy inspection noting leaks is a nudge to sort them promptly.

Popular questions

Where are the exhaust gaskets on a 2014 Honda Accord?
They’re at the flanged joints: typically between the front pipe and catalytic converter, mid‑pipe to muffler, and on V6 models at the exhaust manifolds where they meet the cylinder heads. Each joint uses a gasket style matched to that flange, so parts differ between I4 and V6.

How often should exhaust gaskets be replaced?
They’re generally replaced whenever that joint is separated during repairs or upgrades. There’s no fixed kilometre interval, however, if a leak is detected during servicing or inspection, the gasket and any spring bolts should be renewed.

What are the signs of a blown exhaust gasket?
Common clues include a ticking or hissing noise that’s louder on cold start, exhaust smell around the engine bay or underbody, visible soot at a flange, and sometimes a check engine light due to skewed O2 readings. Any of these warrant a quick check on a hoist.
