4. Check the camshaft bearing for wear. If a new
bearing is needed, use a suitable adapter to press
the bearing out of the bore. Ensure that the oil hole
in the new bearing faces the front of the block.
The oil hole in the bearing must be aligned with
the oil hole in the cylinder block. The bearing must
be aligned with the face of the recess. Refer to
Disassembly and Assembly, "Camshaft Bearings

1. Remove the cylinder head from the engine.
2. Remove the water temperature regulator housing.
3. Inspect the cylinder head for signs of gas or
coolant leakage.
4. Remove the valve springs and valves.
5. Clean the bottom face of the cylinder head
thoroughly. Clean the coolant passages and
the lubricating oil passages. Make sure that the
contact surfaces of the cylinder head and the
cylinder block are clean, smooth and flat.
6. Inspect the bottom face of the cylinder head for
pitting, corrosion, and cracks. Inspect the area
around the valve seat inserts and the holes for the
fuel injectors carefully.
7. Test the cylinder head for leaks at a pressure of
200 kPa (29 psi).

8. Measure the cylinder head for flatness. Measure
the flatness of the cylinder head with Tooling (A)
and Tooling (B).
•
Measure the cylinder head from one side to the
opposite side (C).
•
Measure the cylinder head from one end to the
opposite end (D).
•
Measure the cylinder head from one corner to
the opposite corner (E).
Refer to Specifications, "Cylinder Head" for the
requirements of flatness.
Remachining the Cylinder Head
The bottom face of cylinder head can be machined if
any of the following conditions exist:
•
The bottom face of the cylinder head is not flat
within the specifications.
•
The bottom face of the cylinder head is damaged
by pitting, corrosion, or wear.
Note: The thickness of the cylinder head must not be
less than 117.20 mm (4.614 inch) after the cylinder
head has been machined.
If the bottom face of the cylinder head has been
remachined, the recesses in the cylinder head for
the valve seat inserts must be machined. The valve
seat inserts must be ground on the side which is
inserted into the cylinder head. Grinding this surface
will ensure that no protrusion exists above the bottom
face of the cylinder head. Refer to Specifications,
"Cylinder Head Valves" for the correct dimensions.
