Cylinder Head
WARNING: This page is about a different variant/trim than selected.
- Inspect for flatness.
Using a precision straight edge and feeler gauge, measure the surface the contacting the cylinder block and the manifolds for warpage.
If the flatness is greater than maximum, replace the cylinder head.
Flatness of cylinder head gasket surface
Standard: Less than 0.05 mm (0.0019 in.) for total area
Less than 0.02 mm (0.0007 in.) for a section of 100 mm (3.9370 in.) X 100 mm (3.9370 in.)
Flatness of manifold mounting surface (Intake/Exhaust)
Standard: Less than 0.10 mm (0.0039 in.)
- Inspect for cracks.
Check the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks. If cracked, replace the cylinder head.
