Noisy V6 injectors and diesel injector seals on the Land Cruiser 150

Engine / equipment

Toyota Land Cruiser 150 (Prado 150), 4.0 V6 petrol and 3.0 D-4D

Period mentioned

2009–2013

Symptoms

V6: noisy injectors. High-mileage diesel: fuel getting past the injector seals and contaminating the oil. Some owners notice a vibration between 1,500 and 2,000 rpm and, on early automatics, a hesitant gearbox.

Possible cause described

According to CarsGuide (Prado is the Australian name of the Land Cruiser), the chain-driven V6 gives little trouble apart from noisy injectors. On the diesel, sludge can block the oil pick-up and destroy the engine if not caught; the seals should be replaced at the valve-clearance check every two years or 40,000 km. The automatic’s hesitation was fixed with a software update.

Check for the garage

Check the service history (injector-seal changes on the diesel) and have the oil pick-up inspected through the sump plug; look for underbody damage from off-road use.
