Cylinder Head Assembly: Testing and Inspection

Cylinder Head Distortion






Head surface flatness:
Less than 0.1 mm (0.004 in).

Note: If beyond the specified limit, replace it or resurface it.

Resurfacing limit:

Note: The resurfacing limit of cylinder head is determined by the cylinder block resurfacing in an engine.

- Amount of cylinder head resurfacing is "A"
- Amount of cylinder block resurfacing is "B"
- The maximum limit is as follows:
A + B = 0.2 mm (0.008 in).

Note: After resurfacing the cylinder head, check that camshaft rotates freely by hand. If resistance is felt, the cylinder head must be replaced.

Nominal cylinder head height:
106.8 to 107.2 mm (4.205 to 4.220 in).
