011VD-FTV V8 injector failure leading to melted/cracked pistons
CriticalCommonEngine $3,500–$15,000 to fix
The 4.5 V8 turbo-diesel's Denso common-rail injectors wear internally and erode at the nozzle, especially with contaminated or poor-lubricity fuel and stretched service intervals. A worn injector over-fuels one cylinder, and the classic end-game on 70 Series and 200 Series is a melted or cracked piston - turning a $4,000-8,000 injector job into a five-figure engine rebuild. Diesel specialists on both sides of the Tasman treat injectors as a service item at roughly 150,000-200,000 km. A compression test showing more than about 10% variation between cylinders is a red flag for existing piston damage.
Symptoms to notice
Diesel knock or rattle at idle that wasn't there before
Rough running or misfire, especially when warm
White or black smoke under load
Diesel smell and poor fuel economy
Hard starting
What to check
Ask for invoices showing injector replacement - on anything over 150,000 km with original injectors, budget for the job. Listen at idle from cold for uneven knocking. Insist on a compression test or at least a diagnostic scan of injector correction values as part of the pre-purchase inspection. Check the fuel filter service history; skipped filters kill injectors.
Where to look: Top of the engine under the intake plumbing, one injector per cylinder (V8); symptoms heard at idle from the engine bay
Ask the seller
“Have the injectors ever been replaced, and at what km?”
“How often were fuel filters changed?”
“Has a compression test been done recently, and what were the numbers?”
The solid front axle's swivel housings seal with a felt/rubber/steel wiper arrangement that wears with age, dirt and water crossings. Leaking swivels sling grease or oily sludge onto the inside of the front wheels and tyres (a WoF fail if it reaches braking surfaces), and a failed inner axle seal lets diff oil migrate into the swivel or grease into the diff, thinning both. The full fix is a both-sides strip-down with new bearings and seal kits - routine for any 4WD workshop but several hours per side. It is the single most common leak on any working 70 Series.
Symptoms to notice
Oily grime sprayed on the inside of the front wheels
Grease weeping from the big chrome swivel balls behind the front wheels
Front diff oil level dropping or overfilling with thin grey sludge
Clicking from the front axle on full lock (worn CV/birfield from running dry)
What to check
Crouch at each front wheel and look at the chrome swivel ball behind the brake backing plate - a light smear is normal, dripping sludge is not. Check the inside of both front tyres for slung oil. Turn the steering to full lock and roll forward listening for clicks. Ask when the swivel hubs were last rebuilt - on a farm truck it's a periodic job, not a once-ever job.
Where to look: Front axle swivel housings (chrome balls) directly behind each front wheel
Ask the seller
“When were the swivel hubs last rebuilt and were kingpin bearings replaced?”
“Does the front diff oil get checked between services?”
“Has it done a lot of water crossings or beach work?”
