What you are looking at

What goes wrong

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.

What you would 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

How to check it

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 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.

Parts involved: Fuel injector.

What it costs to put right

$3,500 to $15,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

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?”

Which Toyota Land Cruiser 70 years are affected?
