What you are looking at

No photograph available

We do not hold a verified photograph of the Intake manifold or Turbocharger yet. We would rather show none than show a picture of a different part.

What goes wrong

The rubber intercooler hoses on the HDJ100 age-harden and crack preferentially at the clamp bite points where the hose is under combined mechanical stress and heat cycling. The most failure-prone sections are the large-diameter pipe running from the turbocharger compressor outlet to the front-mounted intercooler, and the pipe from the intercooler outlet to the intake manifold. A split or fully detached pipe results in near-total loss of boost pressure, severe power reduction, heavy black smoke, and potential ingestion of unfiltered air. Replacement with silicone boost hoses and stainless clamps is the accepted preventive upgrade.

What you would notice

Sudden loss of power under load or when accelerating hard
Heavy black or grey smoke from exhaust under boost
Audible hissing or whooshing boost leak noise under acceleration
Loud blow-off pop when releasing throttle
Intercooler pipe found loose or detached on inspection

How to check it

Where to look. Intercooler piping running between turbocharger, front-mounted intercooler, and intake manifold on 1HD-FTE engine

Visually trace all intercooler hoses from the turbo outlet through to the intake manifold. Squeeze each rubber section to feel for hardness, brittleness, or surface cracking. Inspect the hose surface at each clamp for splits, bulges, or tears. Verify all clamps are tight and not corroded through. If a workshop inspection is possible: A boost pressure test under load will confirm any leak.

Parts involved: Intake manifold, Turbocharger.

What it costs to put right

$180 to $650 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 intercooler pipes or hoses been replaced or upgraded?”
“Does the vehicle produce full power under heavy acceleration?”
“Has there ever been a boost leak diagnosis or repair?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Toyota Land Cruiser 100 buyer questions

Is 1hd-fte intercooler boost pipe split at clamp serious on a Toyota Land Cruiser 100?

We rate it major and common on the Toyota Land Cruiser 100. The rubber intercooler hoses on the HDJ100 age-harden and crack preferentially at the clamp bite points where the hose is under combined mechanical stress and heat cycling. The most failure-prone sections are the large-diameter pipe running from the turbocharger compressor outlet to the front-mounted intercooler, and the pipe from the intercooler outlet to the intake manifold.

How much does it cost to fix on a Toyota Land Cruiser 100?

$180 to $650 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Toyota Land Cruiser 100 years are affected?

Our research records this fault on the 1998–2007 Toyota Land Cruiser 100. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
