2025 Mitsubishi Eclipse Cross Exhaust Gasket — What It Does and When to Replace It

Yes, the 2025 Mitsubishi Eclipse Cross uses exhaust gaskets. Technical references that back this up include Mitsubishi Motors’ service information for the Eclipse Cross (GK/GL series, 2025MY) and the Mitsubishi ASA electronic parts catalogue, both of which list multiple exhaust gaskets: at the turbo/manifold-to-cylinder-head interface, the turbo outlet to front pipe, and various flange joints further down the system. The workshop procedures specify renewing these gaskets whenever the exhaust manifold, turbocharger, catalytic converter, or front pipe is removed, underscoring that gaskets are fitted and considered consumable sealing parts.

On this model, exhaust gaskets provide a gas-tight seal between hot, high-pressure exhaust components. They’re typically multi-layer steel or graphite/metal composites near the cylinder head and turbo, with crush-type “donut” or flat flange gaskets at pipe joins. Their job is to stop leaks that can cause a ticking sound on cold start, whiffs of exhaust in the cabin, loss of boost or power (on the 1.5T), and even damage to nearby components from hot gas blow-by.

Good servicing practice for an Eclipse Cross in Australia or New Zealand is to inspect for leaks whenever it’s on the hoist—especially after 60,000–100,000 kilometres, or if the exhaust has been disturbed for other work. Look for:

• Soot marks or black streaks around joints and flanges
• Tapping/ticking noises that quieten as the engine warms
• Fumes, a sharp exhaust odour, or a chuffing sound under load

If a joint is opened—say, to remove the turbo, front pipe, or cat—fit new OEM-spec gaskets and new self-locking nuts where specified. Reusing a crushed gasket is false economy, once compressed, it won’t reseal reliably. Follow the service manual torque values and fastener tightening sequence, as uneven clamp load can warp flanges and cause repeat leaks. After the first heat cycles, a check of accessible flange fasteners for proper torque is a smart move.

PHEV variants still use exhaust gaskets for the petrol engine, even with more electric running, heat cycling and corrosion can still age the seals. Coastal driving, short trips, and rough roads can hasten wear, so visual checks during scheduled servicing are well worth it.

Popular questions about 2025 Mitsubishi Eclipse Cross exhaust gaskets

Does the 2025 Eclipse Cross have exhaust gaskets?
Yes. Mitsubishi’s service manual procedures and ASA parts listings show gaskets at the turbo/manifold-to-head, turbo outlet to front pipe, and various flange joins. They’re designed to be replaced when disturbed.

What are the signs an exhaust gasket is leaking on an Eclipse Cross?
Common clues are a ticking noise on cold start, soot around a joint, a sharper exhaust note, exhaust smell near the front of the car, and—on turbo models—sluggish boost response. A mechanic can confirm with a smoke test or by checking for carbon traces.

Can it be driven with a leaking exhaust gasket?
Short trips might be possible, but it’s not recommended. Hot leaks can damage nearby components, fumes can enter the cabin, and on turbo cars you can lose efficiency. It’s best to book a repair and replace the affected gasket and hardware.
