Parts for your 1995 Mitsubishi Pajero-Exhaust gasket

1995 Mitsubishi Pajero exhaust gasket — what it does and when to replace it

Yes, an exhaust gasket is relevant and used on the 1995 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero 1991–1999 Workshop Manual (Engine/Exhaust sections), the Mitsubishi ASA electronic parts catalogue for the V20 series, and common aftermarket catalogues (Victor Reinz, Fel-Pro, Ajusa) all list exhaust manifold gaskets and front-pipe “donut” or flange gaskets for the 2.8L 4M40 diesel and the 3.0/3.5L 6G72/6G74 petrol engines. That means the vehicle relies on several gaskets to keep the exhaust sealed from the cylinder head right through to the front pipe.

On this Pajero, the exhaust gasket’s job is simple but critical: it seals hot gases at the manifold-to-head, manifold-to-front pipe, and various flange joints so there’s no hissing, ticking or fumes under the bonnet. A healthy seal protects oxygen-sensor readings (on petrol variants), keeps torque and spool response crisp (on the turbo-diesel), and helps it pass a WOF or rego check without drama.

As part of routine servicing, it pays to keep an eye—and ear—on the exhaust. If there’s a sharp ticking on cold start, a whiff of exhaust in the cabin at idle, or black soot marks around a flange, the gasket may be on the way out. Heat cycles, off-road vibration and old hardware can flatten or crack gaskets over time.

When replacing, it’s best practice to use new gaskets rather than reusing old ones. Clean both mating faces until they’re flat and free of carbon, then install the correct style (multi-layer steel or composite for the manifold, crush ring/donut or flat gasket for joints). Avoid sealants unless the service manual specifically allows it for that joint—most Pajero exhaust gaskets are designed to go on dry. Fresh studs, nuts and the spring-bolt kit at the front pipe help prevent future leaks. Torque manifold fasteners in a centre-out sequence to the spec in the workshop manual and recheck after the first proper heat cycle if the manual advises.

A few quick tips:

• Soak rusty fasteners with penetrating oil ahead of time.
• Support the system so it isn’t hanging on fresh gaskets.
• If one joint is leaking, inspect the lot—age and heat affect them as a set.

Popular questions about 1995 Mitsubishi Pajero exhaust gaskets

Which exhaust gaskets does a 1995 Pajero use?
Depending on engine and build, it typically has an exhaust manifold-to-head gasket, a manifold-to-front pipe donut or flat gasket, and additional flange gaskets further down the system. Turbo-diesel models also rely on turbo-to-manifold and turbo-outlet gaskets.

What are the signs an exhaust gasket needs replacing?
Cold-start ticking, a hissing note under load, soot deposits at a joint, or a faint exhaust smell near the engine bay are common tells. Petrol variants may show rough idle or poor fuel economy if a pre-cat leak skews sensor readings.

Is it safe to drive with a leaking exhaust gasket?
Short term, it may be drivable, but it’s not ideal. Hot gases can damage nearby components, fumes can enter the cabin, and the engine can lose performance. Best to repair promptly to avoid compounding issues and to stay WOF/regulatory compliant.
