Injector seats and cracked pistons on the 3.0 D-4D (1KD-FTV)

Sources are not verified in real time and no entry confirms that your car is affected.

Engine / equipment: 3.0 D-4D (1KD-FTV): Hilux, Land Cruiser and Dyna
Period mentioned: Approx. 2005–2015
Symptoms: Rattle when cold, rough idle, smoke and blow-by; dirty, sludgy oil and, if the oil pickup blocks, serious engine failure.
Possible cause described: The copper seats under the injectors often failed and let gases into the crankcase: the oil gets dirty and can block the pickup screen. Faulty injectors are also linked to cracked pistons; Toyota issued a bulletin (EG-008T-0112) for Euro IV engines.
Check for the garage: Check for blow-by at the oil filler cap, test the injectors (back-leak test) and inspect their seats; clean the pickup screen if the oil is sludgy.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.
