Parts for your 2017 Mitsubishi Eclipse cross-Exhaust gasket

2017 Mitsubishi Eclipse Cross exhaust gasket

Based on technical sources including the Mitsubishi Motors Eclipse Cross service manual for GK/GL series (2017‑on) and the Mitsubishi ASA electronic parts catalogue, the 2017 Mitsubishi Eclipse Cross does use exhaust gaskets at several joints in the system. Aftermarket catalogues from major gasket manufacturers also list cylinder head-to-turbo/manifold gaskets and turbo outlet/front pipe gaskets for this model, confirming their relevance.

On the turbocharged Eclipse Cross, exhaust gaskets are there to keep hot gases sealed inside the system from the moment they leave the head, through the turbo, and down the front pipe. Their job is simple but critical: prevent leaks, protect nearby components from heat, keep the cabin free from fumes, and make sure the oxygen sensors and turbo see the correct pressures so the engine runs sweet as. Expect a multi-layer steel (MLS) or embossed steel gasket at the head-to-turbo/manifold joint, and a crush/MLS or donut-style gasket at the turbo outlet to front pipe. Further down, flange or donut gaskets are used at other joins depending on spec.

There’s no set replacement interval in the servicing schedule, but they’re a “replace when disturbed” item. Any time the turbo, front pipe or exhaust sections are removed, new gaskets should go in. During routine services—especially when the vehicle’s on the hoist at 20,000 km intervals—it’s smart to check for tell-tales:

• Ticking or chuffing noise on cold start
• Sooty marks around flanges or the turbo outlet
• Whistle under boost, eggy exhaust smell, or a slight drop in power/economy
• Fuel trim or O2 sensor codes caused by false air

Replacement is straightforward for a trained tech but can be fiddly if fasteners are corroded—common in coastal AU/NZ conditions. Best practice looks like this:

• Use quality OEM or reputable-brand gaskets matched to the exact joint
• Clean mating faces carefully, check flanges for warping
• Renew springs, nuts and studs if tired, follow the factory torque sequence and specs
• On V-band or ring joints, ensure the seal ring seats squarely and the clamp is correctly aligned
• Avoid generic exhaust paste on turbo joints, follow the manual for any approved thread prep

Left unattended, an exhaust leak can let carbon monoxide into the cabin and cook nearby components, so if it starts to sound like a tractor, it’s time to sort the gasket promptly.

FAQs

Does the Eclipse Cross use a donut or flat gasket at the turbo outlet/front pipe?
Most variants use a metal crush ring or donut-style gasket with a spring-bolt joint at the turbo outlet to the front pipe. Some markets or revisions may use an MLS flange gasket. The correct style is confirmed against the VIN in the parts catalogue.

How much does it cost to replace an exhaust gasket on a 2017 Eclipse Cross in AU/NZ?
Parts typically range from about $25–$120 per gasket depending on location (turbo outlet vs downstream flange) and brand. Labour can be 0.5–2.0 hours: a front pipe joint is on the lower end, head-to-turbo/manifold can climb if studs are seized. Expect a fitted price roughly in the $180–$500 range, varying with condition and region.

Can exhaust paste or sealant be used instead of a new gasket?
Not on turbo or critical flange joints. High heat and pressure will quickly defeat paste. Use the specified metal gasket and the correct torque procedure. Sealants are only considered on certain slip joints if the factory procedure explicitly allows it.
