The ISUZU Head to Cover Gasket with OEM numbers 8-94391379-0 / 8943913790 is a precision-engineered replacement designed for ISUZU FVZ34, FSR, and FTR series heavy/medium-duty trucks, compatible with 6HK1 diesel engines. This component seals the joint between the cylinder head cover and the cylinder head.
The head to cover gasket is a sealing component installed between the cylinder head cover and the cylinder head:
- Oil Sealing: Creates a reliable seal to prevent oil leakage from the valve train area
- Heat Resistance: Manufactured from specialized heat-resistant and oil-resistant materials for long-term performance
- Contaminant Prevention: Prevents external dust, moisture, and contaminants from entering the valve train
Inspect immediately if any of these symptoms occur:
| Symptom | Probable Cause |
|---|---|
| Visible oil leakage around cylinder head cover | Worn or hardened gasket; loss of sealing capability |
| Increased oil consumption without blue smoke | Oil leaking from cover gasket, not entering combustion chamber |
| Burning oil smell during engine operation | Leaked oil dripping onto hot exhaust components |
| Hardened, cracked, or deformed gasket | Material aging from long-term high-temperature exposure |
| Loose cylinder head cover bolts | Gasket compression set reducing bolt preload |
