| High Light | Heat-resistant Oil-resistant Rubber Cylinder Head Rubber Plug ，OEM Standard Design Valve Cover Rubber Plug ，Compatible with ISUZU 6HE1 Half-moon Seal | ||
The ISUZU Cylinder Head Rubber Plug with OEM numbers 8-94399605-0 / 8943996050 is a precision-engineered replacement designed for ISUZU FVR and 700P series heavy/medium-duty trucks, compatible with 6HE1 diesel engines. This component serves as a core sealing part of the engine — the Cylinder Head Rubber Plug — responsible for sealing openings in the cylinder head cover to prevent oil leaks and contamination.
The cylinder head rubber plug (also known as "valve cover rubber plug" or "half-moon seal") is a sealing component installed on the cylinder head cover. Its working principle includes:
Inspect immediately if any of these symptoms occur:
| Symptom | Probable Cause |
|---|---|
| Visible oil leakage around cylinder head cover | Hardened, cracked, or damaged rubber plug |
| Increased oil consumption without blue smoke | Oil leaking from plug, not entering combustion chamber |
| Hardened, cracked, swollen, or deformed plug | Material aging from long-term high-temperature exposure |
| Burning oil smell during engine operation | Leaked oil dripping onto hot exhaust components |
| Loose cylinder head cover bolts | Seal failure due to compressed or deformed plug |
