Parts for your 2022 Mitsubishi Eclipse cross-Manifold gasket

2022 Mitsubishi Eclipse Cross manifold gasket — what it does and when to replace it

Yes, a manifold gasket is absolutely relevant to the 2022 Mitsubishi Eclipse Cross. Technical sources including the Mitsubishi Motors Service Manual for the 1.5‑litre 4B40 MIVEC turbo (Engine Mechanical section) show both an intake manifold gasket and an exhaust manifold gasket with specific torque procedures. The Mitsubishi ASA electronic parts catalogue also lists these gaskets for the 2022 Eclipse Cross VIN range, and major gasket manufacturers’ catalogues (e.g., Ajusa, Victor Reinz, Fel‑Pro) publish direct-fit intake and exhaust manifold gaskets for this model. So if there’s talk of a “manifold-gasket” on this vehicle, it’s a real, fitted component.

On this turbocharged Eclipse Cross, manifold gaskets do the quiet but vital job of sealing the joints where the manifolds meet the cylinder head. Up top, the intake manifold gasket keeps unmetered air out and boost pressure in, helping the engine idle smoothly and deliver clean response under load. Downstream, the exhaust manifold gasket (typically multi‑layer steel) contains hot exhaust gas, protects nearby components, and ensures the turbo and catalytic converter see consistent flow and pressure. Good gaskets mean fewer leaks, better fuel economy, stable trims, and less chance of that annoying whistle or tick under the bonnet.

They’re not a scheduled “replace every X km” item in Australia or New Zealand, they’re replaced when disturbed or when leak symptoms show up. Any time the intake or exhaust manifold comes off (say for turbo, EGR, or carbon clean work), fresh gaskets are a must. Follow the OEM torque settings and sequence, clean the mating faces properly, and avoid sealants unless the manual specifically calls for them. On the exhaust side, it’s smart to replace tired studs and locknuts and check heat shields while you’re there. If a leak is suspected, look for sooty deposits at the flange, a ticking noise on cold start, a hiss under boost, a faint exhaust smell, or fault codes for lean operation.

• Watch for hissing/whistling under boost and exhaust “ticking” on start-up.
• Check for rough idle, poor fuel economy, or P0171 lean codes.
• Use new gaskets whenever manifolds are removed, don’t re-use old ones.
• Tighten with a torque wrench, in the factory sequence.
• Inspect for warped flanges if a leak persists after replacement.

Does the 2022 Eclipse Cross have both intake and exhaust manifold gaskets?

Yes. The intake manifold gasket seals the intake runners to the cylinder head to keep unmetered air out and boost in. The exhaust manifold gasket seals the hot side between the head and the manifold/turbo assembly to prevent leaks, maintain turbo efficiency, and protect nearby components.

When should the manifold gaskets be replaced?

They’re replaced when a manifold is removed, or if there are signs of leakage. There’s no fixed kilometre interval. If there’s a hissing or ticking noise, soot around the flange, a fuel‑trim or lean fault, or a whiff of exhaust, it’s time to inspect and likely fit new gaskets following OEM procedures.

Is it safe to drive with a leaking manifold gasket?

Not ideal. An exhaust leak can allow hot gases to damage wiring or plastic parts, skew oxygen sensor readings, and reduce turbo response. An intake leak can cause rough running and poor economy. For comfort and engine health, get it sorted promptly.
