Product Description
Cylinder Head Gasket 8-97328868-1 For ISUZU D-MAX 4JJ1 4JK1 — MLS Head Gasket 8973288681
The Cylinder Head Gasket with OEM number 8‑97328868‑1 (also listed as 8973288681, 8‑97328868‑0, and 8‑97328868‑2) is a verified direct‑fit replacement for ISUZU vehicles equipped with the 4JJ1 3.0L turbo‑diesel engine and 4JK1 2.5L turbo‑diesel engine.
Compatible Vehicle Platforms
- ISUZU D-MAX (TFR/TFS) — 2004–present, all generations, both 2.5L and 3.0L variants
- ISUZU MU-X (UCS/UCR) — 2013–present SUV platform
- ISUZU KB / Rodeo (South African and Australian markets) — 4JJ1‑TC applications
- ISUZU N‑Series (NPR, NKR, NLR) — light‑duty trucks with 4JJ1 engine
- Holden Colorado / Rodeo — GM‑badged Isuzu 4JJ1‑TC / 4JJ1‑TCX
- Chevrolet Colorado / Trailblazer (select markets) — 4JJ1‑TC diesel variants
Critical Engine Sealing Functions
- Combustion Seal — Contains extreme pressure generated during combustion (up to 2,000+ psi / 140+ bar) within each cylinder
- Coolant & Oil Passage Sealing — Prevents cross‑contamination between oil galleries, coolant passages, and cylinders
- Compression Maintenance — Maintains proper compression ratio across all four cylinders
Multi-Layer Steel (MLS) Construction
This OE‑spec gasket features Multi‑Layer Steel (MLS) construction — consisting of several thin stainless steel layers with elastomer coatings — specifically designed for modern high‑compression, turbo‑charged diesel engines like the 4JJ1 and 4JK1. MLS technology provides superior durability, excellent bore retention, and resistance to combustion pressure, thermal cycling, and head lift compared to older graphite or composite gaskets.

| Parameter | 4JJ1 (3.0L) | 4JK1 (2.5L) |
|---|---|---|
| Displacement | 2,999 cc | 2,499 cc |
| Bore Diameter | 96.5 mm (approx.) | 93 mm (approx.) |
| Power Output | Up to 130‑147 kW (177‑200 hp) | Up to 100‑110 kW (136‑150 hp) |
| Torque | 380‑430 Nm | 320‑360 Nm |
| Compression Ratio | 17.5:1 — 18.0:1 | 17.5:1 — 18.0:1 |
Gasket Identification — Notch System
⚠️ CRITICAL: The correct cylinder head gasket thickness is determined by measuring piston protrusion above the engine block deck. ISUZU uses a notch/hole system to indicate gasket thickness. This information is critical for correct engine rebuild.
| Number of Notches | Thickness (mm) | Thickness (inches) |
|---|---|---|
| 1 Notch | Approx. 0.85 mm | 0.033″ |
| 2 Notches | Approx. 0.90 mm | 0.035″ |
| 3 Notches | Approx. 1.05‑1.15 mm | 0.041‑0.045″ |
Note: The 8‑97328868‑1 OE number and its equivalents are often supplied as 3‑notch (1.15 mm) gaskets. However, before purchasing, you must verify the original gasket's notch count or measure piston protrusion to select the correct thickness gasket for your specific engine build.
Common Failure Symptoms
| Symptom | Diagnosis |
|---|---|
| White exhaust smoke / coolant loss | Coolant being drawn into combustion chamber |
| Milky oil appearance | Coolant mixing with engine oil — immediate engine damage risk | Bubbles in radiator / overflow tank | Combustion gases entering cooling system |
| Engine overheating without external coolant leak | Loss of compression due to gasket breach |
| Loss of power / rough running / misfire | Leak between adjacent cylinders (common on 4JJ1 between cylinders 2‑3) |
Primary Causes of Head Gasket Failure
- Engine overheating — Most common cause; warps cylinder head, compromising gasket seal
- High mileage — Gasket material fatigue after extended service (typically 200,000‑300,000 km)
- Improper torque sequence — Head bolts not tightened to correct 3‑stage specification
- Reused torque‑to‑yield (TTY) bolts — TTY head bolts stretch during initial tightening and must be replaced, never reused
