Parts for your 2013 Mitsubishi Lancer-Exhaust gasket

2013 Mitsubishi Lancer Exhaust Gasket — What It Is and When To Replace

Per Mitsubishi’s 2013 Lancer Workshop Manual (Group 15: Exhaust System) and the Mitsubishi Motors ASA electronic parts catalogue for the CJ/CF Lancer, this model uses multiple exhaust gaskets. These include a multi‑layer steel gasket between the cylinder head and exhaust manifold on 4B11/4B12 engines, a conical “donut” gasket at the front pipe spring‑bolt joint, and flat ring/flange gaskets further down the system. Turbo variants (Ralliart/Evo) also add gaskets at the turbocharger and downpipe joints.

On a 2013 Mitsubishi Lancer, the exhaust gaskets do a simple but vital job: they seal extremely hot exhaust gases so nothing leaks where pipes and components bolt together. That means quieter running, no nasty exhaust odours sneaking into the cabin, and accurate oxygen‑sensor readings so fuel economy and performance stay on point.

They’re small, inexpensive parts, but they cop a hiding from heat cycles, vibration and road grime. Over time, the sealing material can harden or crush. If someone’s had the exhaust apart for a clutch, gearbox, or catalyst job, the old gasket is often past its best once disturbed. That’s why replacing exhaust gaskets is standard practice whenever joints are undone.

Typical signs a Lancer’s exhaust gasket is on the way out include a ticking or chuffing noise on cold start, a whiff of exhaust near the engine bay, faint soot marks around a flange, or a slight loss of low‑down torque. Left alone, leaks can toast nearby components and skew O2 sensor data, bumping up fuel use.

• Best practice: renew gaskets any time an exhaust joint is separated.
• Use OEM or quality aftermarket equivalents suited to the CJ/CF Lancer engines.
• Clean mating faces, check flanges for warping, replace tired spring bolts.
• Torque fasteners to spec and recheck after a couple of heat cycles.

For owners in Australia and NZ who service at home, it’s an easy add‑on during routine work like manifold removal or cat replacement. Workshops will typically include new gaskets in any exhaust job’s parts list. It’s a tiny outlay that saves headaches, keeps the Lancer quiet and tidy, and helps it pass a WOF/reg or pink slip without drama.

FAQs

Does the 2013 Lancer have an exhaust manifold gasket?
Yes. Non‑turbo 4B11/4B12 engines use a multi‑layer steel gasket between the cylinder head and the exhaust manifold, specified in the Mitsubishi Workshop Manual and ASA EPC. Turbo models also use additional gaskets at the turbocharger interfaces.

Is it safe to drive with a leaking exhaust gasket?
Short trips might be possible, but it’s not ideal. Exhaust leaks can allow fumes into the cabin and may affect O2 sensor readings, hurting fuel economy and performance. Heat from a leak can also damage nearby parts. It’s best to sort it promptly.

How often should exhaust gaskets be replaced?
They’re typically replaced on condition or whenever a joint is undone. If there’s a leak, noise, soot trace, or the system has been apart, fit new gaskets. Many are single‑use crush designs and won’t reseal reliably once disturbed.
