Parts for your 2015 Honda Cr-v-Manifold gasket

2015 Honda CR‑V manifold gasket — what it is, why it matters, and when to sort it

Technical sources confirm a manifold gasket is absolutely relevant on the 2015 Honda CR‑V. The Honda 2015 CR‑V Service Manual (Helm Inc.) includes intake manifold removal/installation procedures that specify replacing the intake manifold gasket. Honda’s official parts catalogues for the 2015 CR‑V list an “intake manifold gasket” for the K24W 2.4‑litre petrol engine. Honda ServiceNews on Earth Dreams engines also notes the K24W’s integrated exhaust manifold design, which means there isn’t a traditional exhaust manifold gasket at the cylinder head on those petrol models, instead, there’s a gasket between the head and the catalytic converter assembly. So yes—manifold gaskets are used on this model, particularly the intake side.

For everyday owners, the manifold gasket on a 2015 CR‑V quietly does big work. Sitting between the intake manifold and the cylinder head, it seals the intake ports so the engine only breathes clean, metered air. When it’s sealing properly, the engine idles smoothly, fuel trims stay tidy, and emissions gear isn’t fighting leaks. On diesel and some market variants with a conventional exhaust manifold, there’s also an exhaust manifold gasket that keeps hot gases inside the system and away from the engine bay.

It’s not a routine “replace by kilometres” item, but it is a replace‑on‑removal part. Any time the intake manifold comes off—for spark plug access on some engines, carbon clean‑ups, or other top‑end work—the service manual calls for a new gasket. If a gasket starts to fail in service, owners might notice:

• Rough or high idle, a tell‑tale whistle or hiss, or a lean fault code
• Poor fuel economy or a slight loss of grunt
• On exhaust side (where fitted): ticking on cold start, exhaust smell in the bay

Good practice when servicing a 2015 CR‑V is to inspect the intake manifold gasket any time the manifold is disturbed. Use an OEM‑quality replacement, fit it clean and dry unless the manual specifies otherwise, and tighten fasteners in the shown sequence to the factory torque. A quick smoke test after reassembly is a smart way to confirm there are no vacuum leaks. For exhaust‑side work on petrol K24W models, focus on the converter-to-head gasket and related sealing rings rather than a head‑to‑manifold gasket.

Left too long, a leaky manifold gasket can drive the fuel trims mad and trigger the MIL. Sort it early and the CR‑V will run sweeter, use less fuel, and keep emissions gear happy.

Popular questions

What are the symptoms of a bad intake manifold gasket on a 2015 CR‑V?
Common signs include a rough or hunting idle, a noticeable hiss from the intake area, higher than normal fuel trims, and sometimes a P0171 (system too lean) fault. You might also notice a slight drop in power or hesitation off the line. A smoke test will quickly reveal any sneaky leaks around the manifold joints.

Does the 2015 CR‑V have both intake and exhaust manifold gaskets?
All models have an intake manifold gasket. On many petrol 2.4‑litre K24W versions, the exhaust manifold is integrated into the cylinder head, so there’s no traditional head‑to‑manifold gasket, instead, there’s a gasket where the catalytic converter bolts to the head. Diesel or other market variants with a separate exhaust manifold will use a conventional exhaust manifold gasket.

How often should the manifold gasket be replaced?
There’s no set interval. Replace the intake manifold gasket whenever the manifold is removed, or if there are leak symptoms. If working on the exhaust side, follow the same rule—renew the relevant sealing gaskets whenever the joint is separated. Sticking with OEM‑grade parts and proper torque helps ensure a long, leak‑free life.
