INSPECTING THE COMPONENTS
1. INSPECTING THE CYLINDER HEAD
(1) Use the straightedge and a thickness gauge to measure strains in
the lower surface of the cylinder head and in the manifold mount-
ing surface. Replace if a measurement reading exceeds the per-
missible limit.
! CAUTION
•
Perform measurement on a flat surface such as a surface
plate to prevent the deformation in the head.
• Do not adjust the bottom surface by grinding or the timing
gear backlash will be changed.
(2) Use the dye penetrant testing (red check) to inspect for crack and
damage on the cylinder head. If found defective, replace the cylin-
der head.
