Información del producto Culata
1. Descripción general del producto
El Toyota 1KZ series diesel engines – including the 1KZ-T (mechanical injection) and 1KZ-TE (electronic injection) – are 3.0L turbocharged indirect injection (IDI) engines. They use a árbol de levas simple en cabeza (SOHC)8-valve aluminum alloy cylinder head and are renowned for their torque and reliability.
However, earlier 1KZ-TE engines are also known for cylinder head cracking issues due to thermal stress, making high-quality aftermarket or upgraded cylinder heads essential for long-term durability.

6. Notas de instalación
- Reemplazar head bolts (TTY) and use new MLS or composite gasket
- Verify proper holgura de válvulas (shim or hydraulic lifters)
- Inspect for coolant passage corrosion and hot spots
- Use correct secuencia de par (typically: 39Nm + 90° + 90°)
- Bleed air from the cooling system thoroughly – 1KZ engines are prone to air lock & overheating
7. Common Cylinder Head Failures & Repair Advice
| Asunto | Síntoma | Causa | Solución |
|---|---|---|---|
| Culata agrietada | Overheating, coolant loss, white smoke | Thin casting around pre-combustion chamber, poor cooling system maintenance | Replace with reinforced head (aftermarket casting with thicker combustion walls) |
| Coolant in oil | Milky oil, high coolant pressure | Cracked head, blown gasket | Pressure test head & block; replace with MLS gasket and new bolts |
| Rayado del árbol de levas | Ticking noise, idle instability | Oil starvation or dirty oil | Replace head or resurface cam bore; change oil filter and inspect galleries |
| Cabeza deformada | Coolant leak or persistent overheating | Repeated overheat cycles | Resurface head (tolerance ≤ 0.05mm); always pressure test before reuse |
