Parts for your 2016 Mitsubishi Lancer-Oil pump

2016 Mitsubishi Lancer oil pump — what it does and how to look after it

Based on technical references — Mitsubishi Factory Service Manual for Lancer (2015–2017, Group 12: Engine Lubrication), Mitsubishi ASA/CAPS parts catalogue, and the Haynes Repair Manual for Mitsubishi Lancer 2007–2017 — the 2016 Mitsubishi Lancer is absolutely fitted with an engine oil pump. It’s a crankshaft-driven, trochoid-type pump integrated into the front timing case, supplying pressurised oil to bearings, camshafts, the timing chain area and variable valve timing hardware. So yes, the oil-pump is relevant to every 2016 Lancer petrol variant (2.0L 4B11 and 2.4L 4B12).

On a 2016 Lancer, the oil pump’s day job is simple but critical: pull oil from the sump, build pressure, and feed it to the engine’s moving parts so they stay lubricated and cool. It also helps the hydraulic timing and VVT systems behave properly. Without stable oil pressure, things get noisy, hot, and very expensive very quickly.

The oil pump itself isn’t a scheduled service item, but looking after it is all about good oil hygiene. Sticking to the handbook oil-change interval (typically around 10,000 km or 12 months in AU/NZ conditions) with the correct grade and spec oil and a quality filter goes a long way. Keeping the sump topped to the proper level and sorting any leaks promptly protects the pump from running dry or ingesting aerated oil.

• Warning signs to watch: low oil pressure light (especially at hot idle), rattly timing-chain noise on start-up, lifter tick, rising engine temps, or metallic glitter in drained oil.
• If the oil light comes on while driving, the car should be switched off and towed. First check oil level, then verify actual pressure with a mechanical gauge.

Replacement isn’t routine, but it’s sometimes done during timing cover work or an engine rebuild. On the Lancer’s 4B-series engines, access requires removing the drive belts, crank pulley, timing components and front cover. A technician will reseal the front case with the correct FIPG/RTV, fit a new front crank seal, inspect the pickup and O-ring, and prime the pump with clean oil before start-up. It’s a moderate-to-advanced job best left to a workshop with the right tools and torque specs. Expect several hours’ labour, doing fresh oil and filter, and checking the timing chain guides while in there, is smart money.

Bottom line: keep clean oil flowing and the Lancer’s oil pump will quietly do its job for a very long time.

Does the 2016 Mitsubishi Lancer definitely have an oil pump?

Yes. Mitsubishi’s Factory Service Manual (2015–2017 Lancer, Group 12: Engine Lubrication), the ASA/CAPS parts catalogue, and Haynes all document a crank-driven, trochoid oil pump integrated in the front timing case on the 2.0L 4B11 and 2.4L 4B12 engines.

When should the oil pump be replaced on a 2016 Lancer?

There’s no set interval. It’s replaced if there’s confirmed low oil pressure, internal wear/damage, major sludge contamination, or when the front case is off for other repairs and the pump shows out-of-spec clearances. Always verify pressure with a mechanical gauge before condemning the pump.

What’s the best way to extend oil pump life on a 2016 Lancer?

Use the correct oil grade/spec, change oil and filter on time, keep the oil level up, fix leaks quickly, and avoid extended high-RPM running when oil is cold. Those habits protect the pump and the rest of the engine.
