Cylinder Head Inspection
Clean
- Clean the sealing surfaces.
Inspect
- Inspect the cylinder head for the following.
- If the cylinder head is cracked or damaged, it must be replaced. No welding or patching of the cylinder head is recommended.
Measure
- Measure the clearance between the straight–edge and the cylinder head deck face using a feeler gauge at four points along the straight–edge.
- Check the sealing surfaces for deformation and warping. The cylinder head sealing surfaces must be flat within 0.05 mm (0.002 in.) maximum.
- Measure the height of the cylinder head from sealing surface to sealing surface. The cylinder head height should be 129.9 to 130.1 mm (5.1142 to 5.1220 in.). If the cylinder head height is out of specifications, replace the cylinder head.
