What to look out for

The checks worth doing on a Mitsubishi Galant Fortis before you hand over any money. Every documented fault is listed below, each with its own page.

Common issue
Inspect high-pressure hose full length including crimped ends for weeping or staining.
See why
Power Steering Hose and Rack Seal Leaks
Standard Lancers with hydraulic power steering develop leaks at the high-pressure hose crimped ends and at the rack pinion seals. The high-pressure hose is routed close to the exhaust and heat causes the rubber to harden and crack at the metal crimp fittings. Rack seals also deteriorate with age, producing slow weeps that contaminate the subframe and inner CV boots. Power steering fluid loss causes increasing steering effort and can lead to pump damage if ignored.
What you would notice
- Power steering fluid puddle under front of vehicle
- Stiff or heavy steering, particularly at low speed
- Whining or groaning from power steering pump
- Visible oily residue on power steering rack or subframe
- Burning smell from fluid dripping on exhaust
Typically $180–$650 to put right.

014B11T Timing Chain Tensioner Wear at High Mileage (Evo X)

Listen carefully on cold start for a metallic rattling from the top of the engine.petrol2007–2016EngineDoes not apply$1,500–$5,000

OccasionalEngine $1,500–$5,000 to fix

Does not apply

Unlike the belt-driven 4G63, the 4B11T uses a timing chain. The chain tensioner and guide rails are subject to wear at high mileage, particularly on vehicles that have had infrequent oil changes or that have been used on track. A worn tensioner causes the chain to develop slack, producing a rattling noise on cold start that may clear once oil pressure builds. If chain slack is not addressed, the chain can jump a tooth or fail entirely, causing catastrophic valve and piston damage. This failure becomes more prevalent above 150,000 km.

Symptoms to notice

Cold-start rattle from top of engine that clears after 5–10 seconds
Persistent chain rattle at idle that does not clear
Rough idle or misfires if chain has jumped a tooth
Check engine light with camshaft position timing codes
Engine knock or catastrophic failure if chain breaks

What to check

Listen carefully on cold start for a metallic rattling from the top of the engine. If rattle is present, do not dismiss it as normal warm-up noise — it indicates tensioner wear. Retrieve fault codes — timing position codes P0016/P0017 or similar indicate chain slack. Ask about oil change frequency; infrequent changes accelerate tensioner wear.

Where to look: Front and top of engine block, inside timing chain cover

Parts involved: Timing chain.

Ask the seller

“Does the engine rattle on cold start and does it clear quickly?”
“How frequently was the oil changed and what type was used?”
“Has a check engine light appeared with any timing or camshaft codes?”

024B11 Oil Pump Drive Gear Wear

Check oil level and colour on dipstick.petrol2007–2017EngineDoes not apply$800–$4,500

OccasionalEngine $800–$4,500 to fix

Does not apply

The 4B11 2.0L engine uses a chain-driven oil pump whose drive gear teeth wear prematurely, particularly on vehicles with infrequent oil changes or those that have been run low on oil. As the gear degrades, oil pressure drops progressively until the warning light illuminates. At that point bearing surfaces and crankshaft journals can be damaged within seconds of continued running. The failure mode is sudden rather than gradual and often results in total engine loss requiring replacement.

Symptoms to notice

Oil pressure warning light illuminates at idle or under load
Ticking or knocking from lower engine block
Oil pressure gauge reading low
Engine seizure in unaddressed cases

What to check

Check oil level and colour on dipstick.
Inspect oil filler cap for sludge or creamy residue.
Request full logbook service history to verify oil changes at or under 10,000km intervals.
With engine warm and idling, listen for any lower-block ticking.
Check for any history of oil pressure warning light events.

Where to look: Front of engine block, oil pump assembly behind timing cover

Ask the seller

“Can you provide the full logbook or service receipts showing oil change dates and mileages?”
“Has the oil pressure warning light ever illuminated while driving?”
“Has the engine ever been run with low oil or overheated?”

054B10 MIVEC Cam Oil Passage Sludge & P0011

Scan for P0011 and P0021 codes.petrol2007–2017EngineDoes not apply$600–$3,500

OccasionalEngine $600–$3,500 to fix

Does not apply

The 4B10 1.8L MIVEC engine is susceptible to oil sludge accumulation in the Variable Valve Timing oil control solenoid passages and camshaft sprocket oil feed galleries when oil change intervals exceed 5,000 km or conventional mineral oil is used. Sludge restricts oil flow to the cam phaser, triggering P0011 (Camshaft Position Timing Over-Advanced Bank 1) and P0021. Progressive oil starvation leads to intake camshaft lobe and follower wear, particularly on the variable timing lobe profiles. In severe cases, camshaft lobe scoring occurs without further warning beyond the initial DTC illumination.

Symptoms to notice

P0011 or P0021 camshaft timing fault code stored
Rough idle or hesitation during warm-up phase
VVT solenoid ticking or buzzing at idle under load
Reduced power above 3000 rpm due to VVT malfunction
Noisy valve train after prolonged idling

What to check

Scan for P0011 and P0021 codes.
Remove oil filler cap and inspect rocker cover interior for sludge deposits with a torch.
Confirm oil change history shows intervals of 5,000 km or under with full synthetic 5W-30.
Check oil pressure at idle.
If a workshop inspection is possible: Remove and inspect VVT solenoid screen filter for blockage.

Where to look: Top of engine, intake camshaft phaser unit, VVT oil control solenoid, camshaft bearing journals

Ask the seller

“What has been the oil change interval and type of oil used throughout ownership?”
“Has a P0011 or any camshaft timing fault code ever been present?”
“Has the VVT solenoid or cam phaser ever been replaced or the passages flushed?”

06Diesel EGR Valve Carbon Sticking & Rough Idle

Scan for P0401, P0402, P0404, and P0405 EGR codes.diesel2007–2017EngineDoes not apply$450–$1,500

OccasionalEngine $450–$1,500 to fix

Does not apply

The 2.0 DI-D diesel variant of the Lancer CJ suffers from Exhaust Gas Recirculation valve sticking in the partially open or closed position due to carbon deposit accumulation on the valve pintle and seat from short-trip urban use. A sticking-open EGR valve introduces excess exhaust gas into the intake at idle, causing rough idle, diesel knock, and misfires. A sticking-closed valve triggers P0401 insufficient flow faults and raises NOx output. The EGR cooler passages on this engine are also prone to carbonisation from low-load operation, compounding the restriction. Symptoms worsen progressively and MIL illumination typically precedes drivability deterioration.

Symptoms to notice

Rough idle or diesel knock at normal operating temperature
P0401 EGR flow insufficient or P0404 EGR control circuit fault code
Black or grey smoke from exhaust at light throttle
Hesitation or stumble pulling away from idle
Check engine light with EGR-related DTCs stored

What to check

Scan for P0401, P0402, P0404, and P0405 EGR codes.
Remove EGR valve and inspect pintle and seat for carbon binding.
Test valve movement manually and with 12V applied to actuator.
Inspect EGR cooler inlet tube for carbonisation restricting flow.
Check intake manifold for soot accumulation indicating recirculation override.

Where to look: EGR valve on exhaust manifold, EGR cooler, intake manifold EGR inlet port

Parts involved: EGR valve.

Ask the seller

“Has the EGR valve ever been cleaned, reconditioned, or replaced?”
“Are there any stored engine fault codes currently or in recent history?”
“Has the vehicle been used predominantly for short urban trips?”

074B11 MIVEC Oil Control Valve Sludge Failure

Connect a scanner and check for MIVEC or VVT fault codes.petrol2007–2015EngineDoes not apply$300–$900

CommonEngine $300–$900 to fix

Does not apply

The CY4A Galant Fortis 4B11 2.0 MIVEC variable valve timing oil control valves clog with sludge from infrequent or low-quality oil changes, causing the MIVEC system to fail and illuminating a check engine light with MIVEC fault codes. The 4B11 requires oil changes every 5000km with the correct specification to prevent sludge accumulation in the narrow OCV passages.

Symptoms to notice

Check engine light with MIVEC or VVT-related fault codes at startup
Rough idle on cold start that improves once the engine reaches operating temperature

What to check

Connect a scanner and check for MIVEC or VVT fault codes. Rough idle on cold start that improves after warm-up indicates MIVEC solenoid sludge. Ask about oil change history — intervals beyond 7500km increase sludge risk significantly.

Where to look: 4B11 MIVEC oil control valve solenoids on each cam, top of engine

Ask the seller

“Has the 4b11 mivec oil control valve been inspected or repaired?”

08Throttle Body Carbon Fouling

02Front Lower Arm Inner Bush Failure & Steering Shimmy

With vehicle safely raised, grip the lower arm at its inner pivot point and apply fore-aft and lateral force.2007–2017SuspensionDoes not apply$450–$1,000

CommonSuspension $450–$1,000 to fix

Does not apply

The front lower control arm inner pivot bushes on the CJ Lancer and CZ4A Galant Fortis degrade prematurely due to the original rubber compound hardening and cracking under NZ road and climate conditions. Failure allows the lower arm to deflect longitudinally and laterally under braking and cornering loads, producing vague steering feel, highway shimmy between 90 and 110 km/h, and wander on cambered roads. The bush deflection moves geometry beyond alignment compensation limits, causing accelerated front tyre edge wear. Both lower arms typically require simultaneous bush replacement to permit correct caster and camber alignment.

Symptoms to notice

Steering shimmy or vibration between 90 and 110 km/h on motorway
Vague or wandering steering requiring constant correction
Uneven or feathered tyre wear on front inner or outer edge
Clunk from front suspension over road joints or undulations
Vehicle pulling under braking

What to check

With vehicle safely raised, grip the lower arm at its inner pivot point and apply fore-aft and lateral force.
Any movement beyond minimal indicates bush failure.
Inspect visually for split, extruded, or cracked rubber.
Check front tyre wear pattern for edge scalloping.
Test drive at 90 to 110 km/h for shimmy.
Review most recent wheel alignment record.

Where to look: Front lower control arm inner pivot bush, subframe mounting bracket, both sides

Parts involved: Ball joint.

Ask the seller

“Have the front lower control arm inner bushes been replaced?”
“Is there any shimmy or vibration at highway speeds?”
“When was the wheel alignment last checked and what readings were recorded?”
