Mitsubishi Lancer CY

Compact 1.8L diesel for the ASX and Outlander II. Economical but prone to DPF problems with short-trip use and oil dilution from DPF regeneration. EGR fouling is a recurring topic.

• !! Oil dilution from DPF regeneration from 80,000 km

  During DPF regeneration diesel fuel enters the engine oil. Oil level rises instead of dropping. Diluted oil loses its lubricating properties. Early model years particularly affected; Mitsubishi revised the software later.

  Symptoms: Oil level rises above maximum, engine oil smells of diesel, DPF warning light, increased engine noise

• !! Injectors failed from 140,000 km

  Common-rail injectors clog or lose sealing at higher mileages. Return-flow rate increases, leading to starting problems and rough running.

  Symptoms: Difficult cold start, rough idle, power loss, check engine light

• !! Turbocharger failed from 160,000 km

  The turbocharger loses performance through blocked oil lines or bearing wear. Oil lines clogged by DPF-related oil dilution accelerate wear further.

  Symptoms: Whistling from turbo, power loss, blue smoke, oil in the charge air pipe

+ 2 more engine weaknesses + vehicle weaknesses

Solid 4-cylinder naturally aspirated engine with port injection and MIVEC variable valve timing. No turbo, no direct injection — mechanically simple and long-lived. Known weaknesses are oil leaks at the intake manifold and a KBA recall for piston rings on 2011/2012 vehicles.

• !! Recall: piston ring deposits

  KBA recall for ASX models from 2011 and 2012: deposits and sticking on the piston rings lead to loud, rough engine operation and power loss.

• !! Elevated oil consumption from worn piston rings from 120,000 km

  Worn piston rings and failed valve stem seals cause creeping oil consumption. Particularly on vehicles above 100,000 km with neglected maintenance. Threshold: above 300 ml per 1,000 km.

  Symptoms: Blue smoke from exhaust especially on cold start or overrun, rising oil consumption, faint engine oil smell

• ! Oil leak at the intake manifold from 95,000 km

  The gasket between the intake manifold and cylinder head frequently develops oil leaks. The gasket hardens and loses elasticity. Typically occurs in the 80,000–120,000 km range.

  Symptoms: Oil trail on the engine block below the intake manifold, oil smell in the engine bay, dropping oil level

+ 1 more engine weaknesses + vehicle weaknesses

1.8-litre MIVEC naturally aspirated engine with timing chain, successor to the 4G93. Technically closely related to the 4B11 but with less power. Timing chain is maintenance-free but vulnerable if oil is neglected. Oil change every 10,000 km is mandatory — never exceed the interval.

• !! Timing chain stretch (neglected oil changes) from 150,000 km

  The 4B10 timing chain stretches with missed oil changes or incorrect oil viscosity. A ticking noise on cold start is the typical early sign. If ignored, chain failure and engine damage follow.

  Symptoms: Metallic ticking on cold start (disappears after warm-up), engine management warning light, harsh variator shift noise

• !! MIVEC actuator malfunction from 120,000 km

  The MIVEC variable valve timing actuator on the 4B10 is sensitive to old or incorrect engine oil. Oil galleries inside the actuator clog and valve timing response becomes sluggish. Symptoms: power loss in the mid-rev range and engine fault code.

  Symptoms: Power loss between 3,000 and 5,000 rpm, check engine light (P0012/P0022), rough running

• ! Elevated oil consumption at high mileage from 180,000 km

  Some Lancer CY owners report slightly elevated oil consumption from piston ring wear above 150,000–200,000 km. With regular oil changes (10,000 km interval) this rarely reaches a critical level.

  Symptoms: Dropping oil level between service intervals, occasional slight blue smoke on cold start
