| QC Item | Verification Method |
|---|---|
| Fire ring bore alignment | Laser measurement - 92.0 mm ±0.03 mm tolerance |
| Gasket thickness (compressed) | Digital micrometer at 6 points - verified against OE specification |
| Layer registration | Optical inspection - all MLS layers aligned within 0.2 mm of OE drawing |

| Symptom | Diagnosis |
|---|---|
| Gradual coolant loss with no visible external leak | Coolant escaping past the fire ring into combustion chamber |
| White/grey steam from exhaust that continues after engine is warm | Coolant burning in combustion chamber - head gasket breach |
| Bubbles in coolant overflow bottle while engine idles | Combustion gases entering cooling system - definitive sign of failure |
| Pressure in cooling system - hard hoses when engine is cold | Combustion pressure entering cooling system |
| Milky oil residue under filler cap or on dipstick | Coolant mixed with engine oil - internal gasket failure |
