Parts for your 1996 Mitsubishi Pajero-Exhaust gasket

1996 Mitsubishi Pajero Exhaust Gasket — Purpose, Fitment, and Service Tips

Technical sources including the Mitsubishi Pajero/Montero V20-series workshop manual and the Mitsubishi ASA electronic parts catalogue confirm that the 1996 Mitsubishi Pajero uses multiple exhaust gaskets. These are specified at the exhaust manifold-to-cylinder head, manifold-to-front pipe (often a doughnut/ring style), and various flange joints down the system. Major aftermarket catalogues from brands commonly supplied in Australia and New Zealand also list manifold and flange gaskets for the 1996 Pajero across engines like the 2.8L 4M40 turbo-diesel and the 3.5L 6G74 V6, so the part is absolutely relevant to this vehicle.

On a ’96 Pajero, the exhaust gasket’s job is to seal hot gases as they leave the engine, preventing leaks that can cause ticking noises on cold start, fumes in the cabin, lost power, and an MOT/WOF fail. Around the manifold and the front pipe, gaskets also help manage heat and expansion, keeping the system tight as it cycles from cold to operating temperature.

As part of routine servicing, it’s smart to keep an ear and nose out for issues. A sharp ticking from the engine bay, a sooty line at a joint, a whiff of exhaust under the bonnet, or a sudden change in exhaust note are classic signs the gasket is on the way out. Diesels like the 4M40 can make leaks more obvious with black staining.

Whenever the exhaust manifold or front pipe is removed on a Pajero, fit new gaskets rather than reusing the old ones. Heat cycling hardens and compresses them, so reusing is false economy. Follow the workshop manual for torque specs and the correct tightening sequence (usually working from the inner fasteners outward in stages). Check studs and nuts, replace anything stretched, corroded, or seized. On flange joints that use a doughnut gasket, make sure mating faces are clean and the spring bolts and seats are in good nick so the joint can move slightly without leaking.

• Inspect for leaks at every service or before long trips.
• Use quality gaskets rated for the engine and fuel type.
• After initial heat cycles, recheck for any weeping or noise.

Done right, a fresh set of exhaust gaskets keeps the 1996 Pajero quiet, safe, and breathing properly, whether it’s towing, touring, or tackling a high-country track.

FAQs — 1996 Mitsubishi Pajero Exhaust Gasket

What are common symptoms of a leaking exhaust gasket on a 1996 Pajero?
Owners often notice a ticking sound on cold start that softens as the engine warms, a harsher exhaust note, exhaust odour around the engine bay, or visible sooty deposits at a flange or manifold joint. A small loss of low-end torque and a slight increase in fuel use can also show up.

How often should the exhaust manifold gasket be replaced?
There’s no strict kilometre interval. Replace whenever the manifold is removed or when there are leak symptoms. Many Pajeros run their original gaskets for years, but high heat cycles, off-road vibration, or previous repairs can shorten life.

Is it safe to drive with a blown exhaust gasket?
Short term, a minor leak might be drivable, but it can allow exhaust gases into the cabin and can erode mating surfaces over time. It’s best to sort it promptly to avoid safety risks, noise, and potential damage to studs and flanges.
