Parts for your 2020 Honda Cr-v-Exhaust gasket

2020 Honda CR‑V exhaust gasket — purpose, care and when to replace

Based on Honda Service Information (workshop manual) and the Honda genuine parts catalogue for the 2020 CR‑V (including the L15BE 1.5‑litre VTEC Turbo and hybrid variants), the exhaust system uses several gaskets: an exhaust manifold/cylinder‑head gasket, turbo outlet/front pipe gasket (crush/metal ring), and rear flange/donut gaskets at the intermediate and muffler joints. Aftermarket catalogues from major gasket and exhaust brands also list these specific CR‑V exhaust gaskets, confirming they’re fitted to this model.

On this CR‑V, the exhaust gasket’s job is simple but critical: seal the joints so hot gases flow through the catalytic converter and mufflers without leaking. A healthy seal keeps the cabin free of fumes, helps the O2 sensors read accurately, and maintains that factory‑quiet note. On the turbo 1.5, good sealing before the cat helps the engine management keep boost and fuel trims in check.

Exhaust gaskets aren’t a routine replacement item by time or kilometres. They’re replaced when disturbed (for example, during front pipe, turbo, or muffler work) or when there’s evidence of a leak. Using new genuine‑spec gaskets on reassembly is best practice, crush and donut types are single‑use by design.

• Common signs of a leaking exhaust gasket: ticking/raspy noise on cold start, sulphur‑like odour near the front pipe, black soot marks at a flange, or a slight drop in fuel economy.
• If a leak is ahead of the catalytic converter, it can trigger fault codes or a check engine light due to skewed O2 readings.

During servicing, a quick visual and audible check under the vehicle is worthwhile: look for soot traces around flanges and listen for a sharp “pfft” under light throttle. If any section is removed, fit new gaskets, align the flanges squarely, and torque fasteners to Honda’s sequence and specs. Spring‑bolt hardware at front‑pipe joints should move freely, replace fatigued springs and rusted bolts along with the gasket.

Quality matters here. Genuine Honda or reputable aftermarket equivalents that match the correct material (multi‑layer steel at the manifold, metal/crush ring at the turbo or front pipe, graphite/metal‑faced donuts at the rear) will seal better and last longer. A properly sealed system keeps the CR‑V quiet, efficient, and compliant with emissions rules across Australia and New Zealand.

Popular questions about 2020 Honda CR‑V exhaust gaskets

Where are the exhaust gaskets located on a 2020 CR‑V?
They sit at the key joints: between the exhaust manifold and cylinder head, at the turbo outlet to the front pipe on the 1.5‑litre turbo, and at the flanged or donut joints further back toward the muffler. Each joint uses a gasket style matched to temperature and movement at that point.

Do exhaust gaskets need regular replacement?
Not on a set schedule. They’re replaced if leaking or any time the joint is separated during repairs. Because many are crush‑type, reusing them risks poor sealing and repeat work.

Is it safe to drive with a leaking exhaust gasket?
A minor leak may just be noisy, but leaks ahead of the cat can affect sensor readings and emissions, and fumes can enter the cabin. It’s best to have it inspected and sealed properly as soon as practical.
