Parts for your 2019 Honda Cr-v-Manifold gasket

2019 Honda CR‑V manifold gasket — what it does and when to replace it

Yes — a manifold gasket is used on the 2019 Honda CR‑V. Technical references that confirm this include the Honda CR‑V 2017–2019 Service Manual (Honda Service Information), which specifies replacing the intake manifold gasket whenever the manifold is removed, and the Honda Electronic Parts Catalogue for 2019 CR‑V variants, which lists an “intake manifold gasket” for all engines. On the exhaust side, the 1.5‑litre turbo (L15B) has the exhaust manifold integrated into the cylinder head and uses a turbocharger mounting gasket in place of a separate exhaust manifold gasket, while models equipped with the 2.4‑litre engine use a conventional exhaust manifold gasket.

On the 2019 CR‑V, the manifold gasket’s main job is to keep things sealed so the engine breathes properly and cleanly. The intake manifold gasket seals the joint between the cylinder head and the intake manifold, stopping unmetered air sneaking in under the bonnet. That keeps idle smooth, fuel trims in check, and power delivery consistent. On turbo models, a dedicated gasket seals the turbo to the head, doing the exhaust manifold gasket’s role by containing hot gases, protecting nearby components, and ensuring the turbo spools as it should.

There’s no set replacement interval for a manifold gasket — they’re generally a replace-once-disturbed item. If the intake manifold or turbo is removed for other work (carbon clean, injector service, cooling system or timing repairs), a new genuine-quality gasket should be fitted as per the workshop manual. Surfaces must be clean and flat, and the bolts tightened in the specified sequence and torque. When the manifold is off, it’s smart to inspect PCV hoses, vacuum lines, and the throttle body gasket, and replace any perished rubbers while access is easy.
