Parts for your 2016 Honda Odyssey-Exhaust gasket

2016 Honda Odyssey exhaust gasket: purpose, fitment, and service tips

Based on Honda service literature for the 2016 Odyssey (J35 V6) and the Honda genuine parts catalogue, exhaust gaskets are absolutely used on this model. The factory documentation shows multiple sealing gaskets across the exhaust stream, including at the cylinder head to manifold joints and at the flanged and donut-style connections further downstream.

On this Odyssey, exhaust gaskets seal hot gases so they only travel through the catalytic converters and mufflers as intended. They prevent fumes in the cabin, keep noise down, protect nearby components from heat and soot, and help the engine management maintain correct oxygen sensor readings. Because the exhaust expands and contracts with heat, these gaskets are engineered to compress just right, maintaining a tight seal through heat cycles and vibrations.

• Common gasket locations on the 2016 Odyssey:
  • Multi-layer steel (MLS) gaskets between the cylinder heads and each exhaust manifold/catalyst assembly.
  • A compressible “donut”/ring gasket at the manifold-to-front pipe or front pipe joints using spring bolts.
  • Flat flange gaskets further back in the system (mid-pipe to muffler/resonator, depending on trim/market).

Tell-tale signs a gasket is on the way out include a ticking or chuffing noise on cold start, a whiff of exhaust under the bonnet or around the floorpan, visible soot at a joint, a rattle from loose spring bolts, or even a check engine light from skewed O2 readings. In Aussie and Kiwi conditions, short-trip moisture and coastal corrosion can hurry things along.

As part of regular servicing, it’s smart to inspect the Odyssey’s exhaust from front to back: look for black deposits at joints, feel for puffs (carefully, on a cool engine), and check the condition of spring bolts, studs, and hangers. Gaskets aren’t a routine “every service” item, but they should be replaced any time a joint is disturbed, a leak is found, or hardware is corroded.

1. Let the system cool completely, then soak fasteners with penetrant.
2. Support the exhaust to avoid strain on other joints.
3. Replace the gasket and any springs, studs, or nuts that look tired.
4. Align flanges, tighten evenly, and torque to the Honda spec and sequence from the service manual.
5. Start the engine, check for leaks, and recheck torque after a heat cycle if applicable.

Quality matters here: go with genuine Honda or reputable OEM-spec gaskets so they seal properly, cope with heat, and don’t crush too thin. Done right, an Odyssey exhaust gasket should last for years and plenty of kilometres.

Popular questions about 2016 Honda Odyssey exhaust gaskets

How long do exhaust gaskets last on a 2016 Odyssey?
With quality parts and correct torque, many will last well over 150,000 km. Lifespan depends on driving patterns, corrosion exposure, and whether the joint has been apart before. Short trips and coastal air can shorten life.

Can they drive with a leaking exhaust gasket?
It’s not recommended. Besides the annoying noise, leaks can let fumes into the cabin, trigger sensor faults, and potentially damage nearby components. It’s safer and usually cheaper long term to fix the leak promptly.

Should sealant be used with new exhaust gaskets on this model?
No sealant is typically required or recommended for the Odyssey’s factory MLS and donut-style gaskets. Fit clean, dry mating faces and torque to Honda specifications. If the manual calls for a specific compound in a spot, follow that guidance only.
