Parts for your 2017 Mitsubishi Lancer-Oil pump

2017 Mitsubishi Lancer Oil Pump — Purpose, Maintenance and Replacement Advice

Technical sources confirm the 2017 Mitsubishi Lancer is fitted with an engine oil pump and it’s absolutely relevant to servicing. Mitsubishi Motors’ Service Manual for the CF-series Lancer (Engine Mechanical – Lubrication) details a chain-driven trochoid (gerotor) oil pump integrated at the front of the engine assembly on the 4B11 (2.0L) and 4B12 (2.4L) petrol engines. The Mitsubishi ASA electronic parts catalogue likewise lists the Oil Pump Assembly for these models. Industry texts on the 4B1-family engines also describe this internal, crankshaft-driven design, supplying pressurised oil to bearings, camshafts and MIVEC components.

On the 2017 Lancer, the oil pump’s job is to pull oil from the sump, pressurise it, and push it through galleries to protect the crank, rods, cams and timing components. It keeps the film strength up under hard acceleration, hot days, and long Kiwi and Aussie highway runs. Without healthy oil pressure, metal meets metal under the bonnet — and that’s when things get pricey fast.

While the pump itself isn’t a routine replacement item, looking after it is part of smart servicing. Fresh, correct-grade oil and a quality filter protect the pump’s internals and the pressure relief valve. Most local schedules call for oil changes about every 15,000 km or 12 months (whichever comes first), but shorter intervals make sense for lots of short trips, dusty roads, or spirited driving. Always use the viscosity and spec shown on the oil cap and in the owner’s manual.

There are tell-tales when a pump or lubrication system needs attention:

• Oil pressure warning lamp, especially at hot idle
• Top-end ticking, timing rattle, or MIVEC-related fault codes
• Metallic glitter in drained oil or the filter
• Low, unstable pressure readings with a mechanical gauge

If replacement is required, it’s a proper workshop job. The Lancer’s pump is driven off the crank and sits behind covers, so access typically involves removing the sump and front cover, locking timing, and following factory torque and sealant procedures. A good technician will inspect the pickup screen, replace O-rings and seals, check chain and guides, and prime the pump with assembly lube before start-up. After refitting, a measured oil pressure check and a careful first start are essential.

Owners keen to avoid pump drama can stick to clean oil, the right filter, and prompt attention to any warning lights or odd noises. That simple diligence keeps the Lancer’s lubrication system happy for the long haul.

Popular questions about the 2017 Mitsubishi Lancer oil pump

Does the 2017 Mitsubishi Lancer have an oil pump?
Yes. The CF-series Lancer petrol engines (4B11 2.0L and 4B12 2.4L) use a chain-driven trochoid oil pump mounted at the front of the engine assembly. This is documented in the Mitsubishi Motors Service Manual (Engine Mechanical – Lubrication) and shown in the Mitsubishi ASA parts catalogue as the Oil Pump Assembly.

The pump supplies pressurised oil to the crank, camshafts and MIVEC system, so it’s vital for engine longevity.

When should the oil pump be replaced?
It’s not a routine service item. Replacement is considered if there’s verified low oil pressure, internal wear or scoring, a sticking pressure relief valve, or heavy sludge/metal contamination from prior failures. It’s also sensible to assess the pump during major engine work when access is already open.

Before condemning the pump, a workshop should confirm oil level and grade, check for bearing wear, and test with a mechanical gauge.

What are the symptoms of a failing oil pump on a Lancer?
Common red flags include an oil pressure warning at hot idle, new top-end ticking or timing rattle, MIVEC or oil-pressure-related fault codes, and sparkly debris in the oil or filter. Any of these warrant immediate diagnosis to prevent big-end or cam damage.

Stop driving if the oil light stays on and get it inspected — lubrication issues escalate quickly.
