Parts for your 2022 Mitsubishi Eclipse cross-Exhaust gasket

2022 Mitsubishi Eclipse Cross Exhaust Gasket

Based on Mitsubishi technical sources—the Eclipse Cross Service Manual (Group 15: Exhaust) for GK/GL series and the Mitsubishi ASA electronic parts catalogue—the 2022 Eclipse Cross (including the 1.5L turbo-petrol and the PHEV) is fitted with exhaust gaskets. These include the cylinder head–to–exhaust manifold gasket and crush/donut or flange gaskets at the front pipe and other joints. So, an exhaust gasket is relevant to servicing this model.

The exhaust gasket on a 2022 Mitsubishi Eclipse Cross is there to keep hot gases sealed inside the exhaust stream from the moment they leave the cylinder head, past the turbo (on the 1.5T), through the catalytic converter and out the tailpipe. Sealing properly matters for performance, emissions, and comfort. A leak upstream of the turbo can mess with boost and fuel trims, while any leak before the oxygen sensors can skew readings and trigger dash lights.

They’re not a scheduled replacement item, but any time the manifold, turbo, front pipe or cat-back is removed, new gaskets should be fitted. Mitsubishi specifies replacing crush/donut gaskets and any single-use fasteners once disturbed. Avoid silicon sealants on exhaust joints—use the correct multi-layer steel or graphite-style gaskets as listed for the VIN. Faces should be clean and flat, torque fasteners to spec in the sequence shown in the workshop guide, and re-check after a heat cycle if instructed.

Drivers might notice a leak by:

• A ticking or chuffing noise on cold start that sharpens under load
• Exhaust odour in the cabin or around the engine bay
• Sooty traces near joints, a whistle on boost (1.5T), or poorer fuel economy
• Warning lights related to O₂ sensing or catalyst efficiency

If any of that shows up, it’s worth having a technician inspect the manifold gasket and front pipe connections from the head shield back to the mid-pipe. On the PHEV, even though the engine runs less often, the same gasket rules apply—heat cycling still takes its toll.

When replacing, stick with genuine or OEM-grade parts, renew studs/nuts if they’re corroded, and keep oxygen sensor threads clean. A well-sealed exhaust will keep the Eclipse Cross quiet, efficient, and compliant with emissions—exactly how it left the factory.

FAQs

Does the 2022 Eclipse Cross have an exhaust gasket, and where is it?
Yes. There’s a manifold gasket between the cylinder head and exhaust manifold, and additional gaskets (crush/donut or flat flange types) at the turbo/front pipe and other flange joints in the system. They’re shown in Mitsubishi’s service manual and parts catalogue for the GK/GL series.

What are the signs an exhaust gasket is leaking on an Eclipse Cross?
Common tell-tales are a ticking noise at cold start, a sharp hiss or whistle on boost (1.5T), exhaust smell, soot around a joint, and sometimes a check-engine light from upset O₂ readings. Fuel economy can drop, and the cabin may pick up fumes.

Is it safe to drive with a leaking exhaust gasket?
It’ll usually run, but it’s not ideal. Hot gases can damage nearby components, fumes can enter the cabin, and the engine management may overcompensate. For turbo models, pre-turbo leaks can stress the turbo and reduce performance. Best to book it in promptly.
