Parts for your 2016 Mitsubishi Lancer-Oil seals

2016 Mitsubishi Lancer oil-seals: what they do and when to service them

Based on technical references—the Mitsubishi Lancer CJ/CF factory workshop manual (covering 2007–2017), the Mitsubishi ASA electronic parts catalogue, and common aftermarket manuals (e.g., Haynes/Gregory’s)—oil-seals are absolutely fitted to the 2016 Mitsubishi Lancer. The 4B11/4B12 engines and both the manual transaxle and Jatco CVT use multiple oil-seals to contain oil and CVT fluid under the bonnet and around the driveline.

On a 2016-mitsubishi-lancer, oil-seals keep lubricants where they belong, stopping leaks at rotating shafts and housings. They’re small rings of rubber or fluoroelastomer with a spring lip that hugs a shaft as it spins. In day-to-day driving, they help maintain correct oil levels, protect bearings and chains/gears, and keep grime out. When an oil-seal goes hard, shrinks, or is nicked during a past repair, leaks start—and that’s when mess, odours, and wear can creep in.

Common oil-seal locations on a Lancer include:

• Front crankshaft oil-seal (behind the crank pulley)
• Rear main seal (between engine and gearbox/CVT)
• Camshaft oil-seals (front of cylinder head/timing cover area)
• Transaxle/differential side oil-seals (where the driveshafts enter the gearbox or CVT)
• Input/output shaft and selector shaft seals in the transaxle

Servicing advice for a 2016-mitsubishi-lancer oil-seals setup is straightforward. There’s no fixed kilometre interval to replace seals
