Parts for your 2013 Mitsubishi Lancer-Oil pump

2013 Mitsubishi Lancer oil pump — purpose and servicing

Based on factory references — Mitsubishi Lancer CJ/CF Workshop Manual (Engine Lubrication group) and the Mitsubishi ASA electronic parts catalogue for 2013 model-year powertrains (4B11/4B12 petrol, 4B11T turbo, and 4N13 diesel) — the 2013 Mitsubishi Lancer is fitted with a crankshaft-driven gerotor oil pump, integrated into the front (timing) case. So yes, an oil pump is absolutely relevant on this model and is a serviceable component.

The oil pump’s job is to circulate engine oil under pressure to the bearings, camshafts and MIVEC hardware, timing chain, and on turbo models, the turbocharger. It keeps a stable oil film between fast-moving parts, carries away heat, and helps wash out wear particles into the filter. Without a healthy pump and clean oil, the Lancer’s engine can suffer rapid wear, low oil pressure warnings, or timing chain noise from poor lubrication.

For everyday servicing, the smartest move is to prevent pump issues before they start. Stick to the service schedule for oil and filter changes (typically every 10,000–15,000 kilometres or 12 months, depending on use), use the correct viscosity and spec listed in the owner’s manual, and avoid excessive sealant during sump or front cover work — stray silicone can clog the pickup strainer and starve the pump.

• Watch for clues: oil pressure warning lamp flickers at idle, rattly starts, a faint bottom-end knock, turbo whine (on Ralliart/Evo), or fault codes for low oil pressure. Metallic glitter in drained oil or a collapsing filter can also be red flags.
• When replacement is needed: it’s a moderate-to-major job because the pump is part of the front case. Expect crank pulley and timing cover removal, with careful resealing. Best practice is to replace the front crank seal and pickup O-ring, clean the pickup and sump, prime the pump with clean oil before refitting, and torque everything to spec from the workshop manual. High-kilometre engines might benefit from inspecting the timing chain, guides and tensioner while you’re in there.

Most shops in Australia and New Zealand quote roughly 5–8 hours labour depending on variant, with parts varying by engine and brand. Using quality OEM or reputable aftermarket parts and proper sealant goes a long way to keeping that Lancer happy for many more kilometres.

Popular questions

Does a 2013 Mitsubishi Lancer actually have an oil pump?
Yes. All 2013 Lancer engines (petrol and diesel, including turbo variants) use a crank-driven gerotor pump in the front case. This is confirmed in the Mitsubishi workshop manual and the factory parts catalogue.

What are the signs the oil pump might be failing?
Low oil pressure warnings, rattly cold starts, louder-than-normal timing chain noise, or bearing knock are common symptoms. On turbo models, you might notice turbo noise or smoke from poor lubrication. Always verify with a mechanical oil pressure test before condemning the pump.

How often should the oil pump be replaced?
There’s no fixed interval — they generally last the life of the engine if serviced well. Replacement is considered when there’s verified low oil pressure, internal pump wear, a stuck relief valve, contamination damage, or when the front case is off for major work.
