Defect: Vegetation can accumulate around the underbody and exhaust system when driving in dry vegetation; if not cleared per maintenance instructions, DPF periodic regeneration heat may ignite it.
Hazard: Fire risk from ignited vegetation.
Remedy: Toyota dealer fits modified exhaust heat shields and enables a DPF manual-regeneration customisation mode.
Affected: 22,971 units, LandCruiser 70 Series (VDJ76/78/79) 2016-2020

Overview
The 70 Series is Toyota's longest-running LandCruiser line and the definitive Australian heavy-duty 4WD - a leaf/coil live-axle, part-time dual-range workhorse sold continuously since 1984 as the troopcarrier (HZJ75 then HZJ78/VDJ78 'Troopy') and, from 2007, the five-seat 76 wagon. Body styles relevant here are the wagon and the Troopcarrier; the utes are catalogued separately. Engine history spans the early carburetted 3F 4.0 petrol six and 2H/3B naturally-aspirated diesels, the long-serving 1HZ 4.2 indirect-injection diesel six and 1FZ-FE 4.5 petrol six (1990s-2007), the iconic 1VD-FTV 4.5 turbo-diesel V8 (2007-2024, single-turbo 151kW/430Nm in the 70 unlike the twin-turbo 200), and from 2023-24 the modern 1GD-FTV 2.8 four-cylinder turbo-diesel paired (for the first time in a 70) with a six-speed automatic. Brutally simple, immensely capable off-road and almost endlessly rebuildable, but old-school in ride, refinement and safety. Buy on engine, service history and rust - the chassis and driveline are the easy part. The factory-narrow front track, recirculating-ball steering and live-axle geometry make the 70 famous for 'death wobble' if the front end is worn or a lift is fitted without caster correction.

- Strong resale - the V8 70 is now a sought-after collectible
Cons
- Only ever offered with a 5-speed manual (no auto on the V8)
- Eight injectors and seals make injector work expensive
- Post-2016 DPF dislikes short urban running
- Thirsty and slow by modern standards; gearing is tall and noisy
Known problems
high
Injector seal failure / 'black death' carbon leak
Worn injector copper seals let combustion gases blow past, baking a hard tar-like carbon ('black death') around the injector and into the head; injectors themselves also wear and over-fuel, causing smoke and rough running.
Fix: Replace injector seals (and injectors as a set if worn) early; fit a quality secondary fuel filter and use clean diesel. Catching it early avoids head damage.
high
Oil pickup strainer / oil-filter cap debris starving the pump
The plastic oil-pickup strainer and the cartridge oil-filter cap spout can break up; debris or a sucked-in filter restricts oil flow and can wipe out bearings. Low oil pressure at idle is an early warning.
Fix: Use genuine filters, fit the cap correctly, and consider replacing the factory pickup/strainer. Investigate any low idle oil pressure immediately.
medium
DPF clogging on short trips (2016/2017+)
Updated emissions models added a DPF that won't passively regenerate on short, low-speed urban runs, leading to soot loading, forced regens, oil dilution and back-pressure.
Fix: Regular highway running to allow regen; address early before it stresses the turbo/EGR. Some owners fit catch-cans to reduce intake oiling.
medium
Cracked exhaust manifolds / EGR cooler issues
Hard-worked and tuned engines crack exhaust manifolds and accumulate intake/EGR soot; over-fuelling tunes raise back-pressure and shorten turbo life.
Fix: Replace manifolds, clean EGR/intake, keep any tune conservative.

Timing chain / belt / gear
Chain-driven
Pros
- Brings a six-speed automatic to the 70 for the first time
- More torque (500Nm) and far better economy than the old V8
- Modern safety and driver-assist not available on V8 stock
- Easier to drive in traffic and on long highway stints
Cons
- Lacks the character and cult appeal of the V8
- Same 1GD that drew DPF/oil-consumption complaints in HiLux/Prado/Fortuner
- Four-cylinder works harder than the V8 when heavily loaded/towing
- Long-term durability in the heavy 70 platform is still unproven
Known problems
medium
DPF white smoke / clogging (class-action history)
The 1GD in HiLux/Prado/Fortuner (Oct 2015-Apr 2020 build) was the subject of an Australian class action over DPF white smoke and incomplete regens; Toyota revised the software and says the 70 application is improved, but short-trip DPF loading remains the engine's key watch-point.
Fix: Ensure all DPF/ECU software updates are applied; do regular highway runs; service on time.
medium
High oil consumption / oil dilution
Early 1GD engines reported high oil consumption and fuel dilution of the oil tied to DPF regen cycles, prompting a software fix; check oil level and condition between services.
Fix: Apply the latest software, monitor oil level/condition, change oil on or before interval.
low
EGR / intake carbon build-up
Like most modern common-rail diesels, soot accumulates in the EGR and intake over time, dulling response.
Fix: Periodic intake/EGR clean; quality oil and clean diesel.

Timing chain / belt / gear
Gear/chain-driven (no rubber timing belt) - very robust
Pros
- Mechanically simple indirect-injection diesel - no electronics to fail
- Legendary high-km durability (500k+ km, fleet examples beyond 700k)
- Easy to work on anywhere; massive global parts support
- Sought-after touring engine, often turbo'd safely with a healthy build
Cons
- Genuinely slow - struggles loaded, towing or on hills NA
- Indirect injection runs hot in the head; cooling must be perfect
- Smoky and tired if the injection pump/injectors are worn (most are old now)
- Thirstier than its small displacement suggests when worked
Known problems
high
Cracked cylinder head from overheating
The aluminium IDI head runs hot and cracks between cylinders/precombustion chambers if the engine overheats even once - a poor radiator, tired fan clutch or hard NA work in heat is the usual trigger.
Fix: Keep cooling immaculate (radiator, fan clutch, coolant, thermostat). Replace/recondition the head if cracked; upgrade cooling on any turbo conversion.
medium
Injection pump and injector wear / timing drift
The mechanical pump can drift timing and wear with age, and injectors tire, causing hard starts, black smoke, rattle and lost power.
Fix: Diesel-specialist pump re-time/rebuild and injector service. Many have had this done - ask for records.
low
Age-related ancillaries and oil leaks
These engines are decades old; expect rear main/front seal weeps, perished hoses, tired mounts and a slow oil drip somewhere.
Fix: Budget a consumables and seal refresh on purchase.

Timing chain / belt / gear
Chain-driven (no scheduled belt)
Pros
- Smooth, torquey, durable big petrol six - timing chain, no belt service
- Cheaper to buy than the diesels because petrol scares buyers off
- Cast-iron block, popular and strong forced-induction base
- Easier cold starting and quieter than the IDI diesel
Cons
- Very thirsty (16-20 L/100km), poor range without LPG/long-range tank
- Head-gasket failures, especially on early (1992-1995) and overheated examples
- Less torque-per-litre feel than a turbo-diesel for heavy towing
- Weaker resale than the diesel variants
Known problems
high
Head gasket failure
The composite head gasket degrades, most commonly on 1992-1995 engines and any with an overheat history - symptoms are white smoke, milky oil, coolant loss and overheating.
Fix: Head gasket replacement with a quality (often metal) gasket, head check/skim, and a cooling-system overhaul at the same time.
medium
Exhaust manifold / Y-pipe cracking and rust
Manifolds, Y-pipe and cats corrode and crack with age, causing leaks and a ticking exhaust.
Fix: Replace manifold/Y-pipe; aftermarket extractors are common.
low
Fuel thirst
Not a fault, but 16-20 L/100km is the reality; many were converted to LPG.
Fix: Quality LPG conversion or accept the fuel bill; long-range tank for touring.

Timing chain / belt / gear
Gear/chain-driven (pushrod OHV)
Pros
- Simple, tough pushrod six - cheap to own and run mechanically
- Cheapest way into an early FJ7x wagon/Troopy
- Takes LPG well; plenty of bush-mechanic knowledge
Cons
- Very thirsty for modest power; carburettor (3F) needs setup know-how
- All examples are now old and high-km - condition is everything
- Slow and gutless next to later engines
Known problems
medium
Carburettor wear / tuning (3F)
The carburetted 3F suffers from worn/gummed carbs and aged vacuum lines causing hard starting, stalling and flat-spots; the later 3F-E EFI is generally easier to live with.
Fix: Carb rebuild/clean and replace perished vacuum hoses; specialist tune.
medium
Fuel thirst and age-related wear
17-22 L/100km plus decades of wear - expect tired cooling, electrics, seals and bushes.
Fix: LPG to manage fuel cost; budget a full consumables refresh.

Timing chain / belt / gear
Gear-driven timing - extremely robust
Pros
- Dead-simple mechanical IDI diesels - no electronics at all
- Gear-driven timing, easy to repair in the bush
- Frugal for the era; cheapest diesel entry to an early 70
- Superseded by the better 1HZ, so often very cheap
Cons
- Slow and weak even by NA-diesel standards (especially the 3B four)
- All are very old and high-hour now - condition over spec
- 2H is heavy on the cooling system; head/gasket risk if neglected
- Smoky if injection pump/injectors are worn
Known problems
high
Overheating / head gasket and cracking
Like all the IDI Toyota diesels, the 2H/3B heads run hot and will gasket-fail or crack if cooling is neglected or the engine is overheated.
Fix: Maintain cooling religiously (radiator, fan clutch, coolant); recondition head/gasket if damaged.
medium
Injection pump / injector wear
Decades-old mechanical pumps and injectors wear, causing smoke, hard starting and lost power.
Fix: Diesel-specialist pump and injector rebuild.
