Cylinder Head

1. Inspect cylinder head for damage, cracks and leakage of water or oil, replacing as necessary.
2. Measure cylinder head distortion. If distortion exceeds .004 inch (.1mm), grind cylinder head surface. Grinding limit is .006 inch (.15mm).
3. On SOHC engines, if cylinder head height is not 4.931-4.935 inches (125.25-125.35mm), replace it.
4. On DOHC engines, if cylinder head height is not 5.707-5.711 inches (144.95-145.05mm), replace it.
5. Measure manifold contact surface distortion. If distortion exceeds .006 inch (.15mm), grind surface or replace cylinder head.
