The engine overhaul gasket kit provides a complete sealing solution during full engine rebuilds. Each gasket and seal has specific functions:
- Cylinder Head Gasket: Seals the combustion chamber between cylinder head and block
- Intake/Exhaust Manifold Gaskets: Seal connections between manifolds and cylinder head
- Valve Cover Gasket: Seals the valve cover to prevent oil leakage
- Oil Pan Gasket: Seals the oil pan to the cylinder block
- Timing Cover Gasket: Seals the timing mechanism cover
- Crankshaft Seals: Includes front and rear main seals to prevent oil leakage
- Camshaft Seal: Seals the camshaft end to prevent oil leakage
| Symptom | Probable Cause |
|---|---|
| Abnormal coolant consumption; oil film in coolant | Damaged cylinder head gasket; cross-contamination between coolant and oil passages |
| White smoke or blue smoke from exhaust | Failed cylinder head gasket; coolant or oil entering combustion chamber |
| Severe oil leakage; oil stains on ground | Worn oil pan gasket, valve cover gasket, or oil seals |
| Reduced compression pressure; power loss | Cylinder head gasket sealing failure; combustion pressure leakage |
| Engine overheating; persistently high coolant temperature | Damaged cylinder head gasket causing coolant circulation issues |
| Visible oil leakage at front or rear of crankshaft | Hardened/worn crankshaft seals; loss of sealing capability |
