Parts for your 2023 Mitsubishi Eclipse cross-Exhaust gasket

2023 Mitsubishi Eclipse Cross Exhaust Gasket — Purpose, Fitment, and Service Advice

Yes, an exhaust gasket is used on the 2023 Mitsubishi Eclipse Cross. Mitsubishi’s Electronic Parts Catalogue (ASA) for the GK-series Eclipse Cross (including the 1.5L turbo petrol and the PHEV) lists multiple exhaust-related gaskets such as the exhaust manifold/cylinder head gasket, turbocharger flange gaskets, and front pipe flange/donut gaskets under Group 15 — Exhaust. The factory Workshop Manual for the GK platform also specifies replacing exhaust gaskets when detaching and refitting the exhaust manifold, turbocharger, front pipe, or other exhaust joints. These technical sources confirm the part is relevant and fitted to this model.

On the Eclipse Cross, the exhaust gasket’s job is to seal joints where hot gases would otherwise escape — at the manifold-to-head interface, around the turbocharger flanges on the 1.5T, and at pipe flanges further downstream. Proper sealing keeps the cabin quiet, protects components from heat-soak, prevents fumes entering the vehicle, and helps the oxygen sensors and catalytic converter do their thing for clean, efficient running.

Owners typically don’t have a time-based replacement interval for exhaust gaskets, they’re replaced when disturbed or if symptoms show up. As part of routine servicing, a workshop should visually check for soot traces around joints, listen for a ticking or hissing on cold start, and scan for fuel-trim or catalyst efficiency faults that can be triggered by upstream leaks. Where a section of the exhaust is removed (for example, to service the turbo or front pipe), Mitsubishi service literature calls for new gaskets on reassembly and tightening in the correct sequence to factory torque.

Quality matters. On the Eclipse Cross, multi-layer steel or graphite/metal ring gaskets designed for turbo heat cycles should be used. Aftermarket can be fine if it meets OE spec, but many technicians prefer genuine parts for durability. In Aussie and Kiwi conditions — frequent short trips, towing, or gravel-road work — periodic checks are smart. If the vehicle fails a WOF/roadworthy for an exhaust leak, a tired gasket is a common culprit and is usually a straightforward fix.

• Typical signs of a failing gasket: ticking on cold start, a whiff of exhaust near the engine bay, visible soot at a flange, reduced performance, higher fuel use, or a check engine light related to mixture or catalyst efficiency.

Popular questions

Does the 2023 Mitsubishi Eclipse Cross actually have exhaust gaskets?
Yes. Mitsubishi’s ASA parts catalogue for the GK-series lists exhaust manifold and flange gaskets, and the Workshop Manual instructs replacing these gaskets whenever the manifold, turbocharger, or front pipe is removed. Both the 1.5L turbo petrol and the PHEV variants use exhaust gaskets at key joints.

How often should Eclipse Cross exhaust gaskets be replaced?
There’s no fixed interval. They’re replaced when a joint is disturbed or if leak symptoms appear. During regular servicing, a technician will check for noise, soot marks, and fault codes. If an exhaust section is removed, fit new gaskets on reassembly and torque to spec.

What are the symptoms of a blown exhaust manifold gasket on this model?
Common signs include a sharp ticking on cold start that softens as the metal heats, a faint exhaust smell in the engine bay, black soot around the manifold or turbo flange, slight loss of torque, and sometimes a check engine light due to false oxygen sensor readings from excess air entering the system.
