4 | Installation Highlights
| Step | Key Points |
|---|---|
| Preparation | Check deck flatness ≤ 0.05 mm; hot‑pressure‑test water jackets. |
| Gasket & Bolts | استخدم دائما new MLS head gasket و مسامير رأس TTY جديدة. |
| Torque Sequence (typ.) | 39 N·m → 90° → 90° (cross pattern, centre‑out). |
| Timing Items | 1KD uses a long‑life chain but inspect guides; 2KD belt & tensioner should be renewed. |
| EGR / Port Match | Ensure correct EGR gallery (EURO 4/5 heads have additional passages). |
| Post‑start Checks | Bleed cooling system; verify rail pressure & VNT actuator function to avoid over‑boost. |
5 | Typical Failure Modes
| الأعراض | السبب المحتمل |
|---|---|
| Coolant loss / overheat | Crack between exhaust seat & coolant jacket or warped head |
| Hard cold‑start & white smoke | Cracked pre‑combustion bowl or low compression |
| Oil‑in‑coolant | Internal crack or gasket blow‑by |
| Power drop & rattling | Valve‑seat recession, cam journal wear, or VNT sticking |

7 | Common Cylinder Head Failures & Repair Notes
(Applicable to 1KD-FTV / 2KD-FTV 2.5L & 3.0L D-4D Engines)
| Failure Mode | أعراض | Causes | Repair/Prevention |
|---|---|---|---|
| رأس الأسطوانة المتصدع | – Coolant loss |
- White exhaust smoke
- Engine overheating
- Pressurized cooling system after cold start – Overheating due to clogged radiator or low coolant
- Excessive turbo boost
- Thin or degraded casting in early OEM heads – Replace head with reinforced casting (e.g. 11101-30050 / 0L060)
- Upgrade to high-quality aftermarket casting
- Always replace radiator and thermostat during head job
تراجع مقعد الصمام – Ticking noise - فقدان الضغط
- Misfire under load – Poor valve material in early models
- Prolonged high-temp operation
- Low-lubricity fuel – Resurface seat and install new hardened valve seats
- Use better quality diesel fuel
- Check valve clearances regularly
Oil in Coolant / Sludge in Radiator – Mayonnaise-like sludge - Oil cooler contamination
- Internal leak – Head-to-block crack
- Failed gasket
- Faulty EGR cooler (in EGR-equipped engines) – Pressure test both head & oil cooler
- Replace gasket and check block deck flatness
- Clean coolant system thoroughly
انفجار رأس الأسطوانة/الحشية المشوهة – Coolant leak externally - Compression leak to coolant
- Overheating under load – Over-torqued head bolts
- Running with low coolant
- Poor-quality head gasket – Machine head flatness (tolerance: ≤ 0.05 mm)
- Replace bolts (TTY bolts must not be reused)
- Use correct torque & angle method
Camshaft Journal Wear / Cam Snap – Loud ticking or knocking - No start
- Uneven valve timing – Poor oil pressure
- Lack of oil changes
- Long idling with poor lubrication – Replace head or reline cam journals (if serviceable)
- Clean oil system thoroughly
- Always use correct 5W-30/15W-40 oil grade
Additional Tips
- 1KD early models (pre-2007) are known for head cracking issues due to thin castings — upgraded OEM versions like 11101-0L060 أو reinforced aftermarket heads are strongly recommended.
- استخدم دائما مسامير رأس TTY جديدة و MLS gaskets rated for turbo-diesel compression.
- EGR-equipped engines (especially Euro 4+) are more likely to overheat due to carbon buildup — regular intake cleaning helps prevent head damage.
- After repair, perform CO2 coolant test و system pressure hold before engine restart.
