Cylinder Head Assembly: Specifications
Cylinder HeadCylinder Head Surface Variation
^ Measure the cylinder head for distortion in six directions as shown in the figure.
^ If it exceeds the maximum specification, replace the cylinder head.
^ Cylinder head gasket contact surface distortion (Maximum) 0.10 mm (0.004 in)
^ Measure the manifold contact surface distortion as shown in the figure.
^ If it exceeds the maximum specification, grind the surface or replace the cylinder head.
Manifold contact surfaces distortion (Maximum) 0.10 mm (0.004 in)
Manifold contact surfaces distortion (Maximum grinding) 0.15 mm (0.006 in)
Cylinder Head Bolt Re-usability
Cylinder Head Bolt Length L
1. Measure the length of each bolt.
^ If it exceeds the specification, replace the bolt.
