Parts for your 2016 Mitsubishi Lancer-Exhaust gasket

2016 Mitsubishi Lancer exhaust-gasket

Yes, an exhaust gasket is absolutely used on the 2016 Mitsubishi Lancer. Technical references including the Mitsubishi Motors Service Manual for CJ/CF Lancer (MY2015–2017, Exhaust section) and the Mitsubishi ASA electronic parts catalogue list multiple exhaust gaskets on this model: a multi‑layer steel (MLS) exhaust manifold-to-cylinder head gasket, a front pipe “donut” gasket with spring bolts, and flat flange gaskets further down the system. Those gaskets seal the joins between the engine, catalytic converter/front pipe, and the rest of the exhaust.

The exhaust gasket’s job is to keep hot gases inside the pipework, limit noise, and make sure the oxygen sensors get accurate readings. If a gasket leaks, expect a sharp ticking or puffing on cold start, a bit of soot around a joint, a whiff of exhaust under the bonnet or near the firewall, and sometimes a check engine light from skewed O2 sensor data. On the Lancer’s 4B11/4B12 engines, a small leak up front can make the engine run off, burn more fuel, and potentially fail a WOF/roadworthy.

There’s no fixed replacement interval, these gaskets are typically replaced when a joint is disturbed or if there’s evidence of leakage. Any time the manifold, catalytic converter, or front pipe is removed, fit new gaskets as per the service manual. Using fresh spring bolts and nuts on the front pipe joint is a smart move, as heat cycling can weaken the old hardware.

• Common signs it’s time: tapping noise on start‑up, exhaust odour in the cabin when stopped, visible soot at a flange, or OBD faults like lean codes or catalyst efficiency errors.
• Service tips for a Lancer: allow the exhaust to cool fully, soak fasteners with penetrant, support the system so it’s not in a bind, clean mating faces, install quality OEM‑spec gaskets, torque to factory specs and sequence (centre‑out on the manifold), recheck fastener tension after a few heat cycles if specified.
• Good “while you’re there”: replace tired hangers, inspect the flex joint, and check O2 sensor wiring and clips.

Done right, new exhaust gaskets keep the Lancer quiet, efficient, and compliant with local emissions and noise regs, while saving the owner from headaches like fumes and false fault codes.

Popular questions about 2016 Mitsubishi Lancer exhaust-gasket

Does a 2016 Lancer actually have exhaust gaskets?
Yes. The CJ/CF Lancer platform uses an MLS manifold gasket, a front pipe donut gasket with spring bolts, and additional flange gaskets downstream. These are documented in the Mitsubishi service manual and parts catalogue for the model years covering 2016.

How often should the exhaust gasket be replaced?
There’s no time or kilometre schedule. Replace gaskets whenever a joint is separated, or if there are symptoms of a leak. It’s best practice to fit new gaskets and often new spring bolts/nuts on reassembly to maintain a proper seal.

Is it safe to drive with a leaking exhaust gasket?
Short trips might be possible, but it’s not recommended. Leaks can let fumes into the cabin, skew oxygen sensor readings, increase fuel use, and create excessive noise. It can also lead to a failed WOF/roadworthy, so it’s worth fixing promptly.
