Parts for your 2024 Mitsubishi Eclipse cross-Exhaust gasket

2024 Mitsubishi Eclipse Cross exhaust gasket — what it does and when to replace it

Yes, the 2024 Mitsubishi Eclipse Cross uses exhaust gaskets. Technical sources including the Mitsubishi Motors Eclipse Cross Workshop Manual (GK/GL series, Group 15: Exhaust System and Group 11: Engine Mechanical) and the Mitsubishi ASA/CAPS electronic parts catalogue for GK/GL and PHEV variants identify multiple sealing gaskets in the exhaust stream. These include the cylinder head–to–exhaust manifold gasket, turbocharger outlet/downpipe gasket on the 1.5L turbo petrol, front pipe “donut” or ring gasket with spring bolts, and rear flange gaskets further down the system. The Eclipse Cross PHEV’s 2.4L petrol engine uses similar manifold and flange gaskets (no turbo gasket on PHEV).

In day-to-day terms, an exhaust gasket keeps hot gases sealed inside the exhaust, so there’s no noisy leak, fumes in the cabin, or false oxygen-sensor readings. On the 1.5T, a tight seal upstream of the turbo also preserves boost response and keeps the ECU happy. These gaskets are usually multi-layer steel or graphite/metal crush rings designed to cope with heat cycles and movement.

They’re not a scheduled replacement item, but they do wear. A gasket is typically replaced when that joint has been disturbed (for example, during turbo, manifold, or muffler work) or when symptoms show up. Single-use crush rings and many MLS gaskets should be renewed every time they’re separated, as per the workshop manual.

• Common signs of a leak: ticking or “puffing” on cold start, soot marks around a flange, a whiff of exhaust near the front of the car, sluggish boost or a whistle on the 1.5T, and sometimes a check engine light from skewed O2 readings.
• Good service habits: inspect flanges, spring bolts and hangers at each service, look for rust, loose hardware, or fresh soot, replace fatigued springs and nuts with new hardware.
• When replacing: use genuine-quality gaskets, follow the factory torque and tightening sequence, and avoid exhaust sealants unless the manual specifies. Heat shields and studs get hot—let it cool and use anti-seize on threads where specified.

Driving in the wet, on gravel, or near the coast can accelerate corrosion, so it’s smart to have the exhaust checked more often. For manifold or turbo gaskets, a pro job is best, lower flanges are DIY-able with stands and the right torque specs from the manual.

Popular questions about 2024 Mitsubishi Eclipse Cross exhaust gaskets

Does the 2024 Eclipse Cross have more than one exhaust gasket?
It does. Expect a manifold gasket at the head, a turbo outlet/downpipe gasket on the 1.5T, a front pipe donut with spring bolts, and rear flange gaskets. The PHEV keeps the manifold and flange gaskets but doesn’t have the turbo outlet gasket.

How often should exhaust gaskets be replaced?
There’s no fixed interval. Replace whenever the joint is disturbed or when there’s a leak. Many owners won’t need one before 80,000–150,000 km, but coastal use and off‑bitumen driving can shorten that. Always renew single-use crush rings and follow the factory torque sequence.

Can a home mechanic replace them?
Lower flange and donut gaskets are achievable with stands, penetrating oil, and a torque wrench. Manifold or turbo gaskets can involve seized studs and tight access—usually better left to a workshop with the Eclipse Cross service manual on hand.
