Cylinder Head Overhaul
1. Progressively slacken the camshaft bearing caps
(Fig. 65, Item 1).
2. Remove the bearing caps (Item 1), oil seals (Item 2),
camshaft (Item 3), tappets (Item 4) and adjustment
shims (Item 5). Mark adjustment shims and tappets so
they will be re-installed in the same location – #1 intake,
#1 exhaust, #2 intake, #2 exhaust, etc.
NOTE: The shims are small and can stick to the tappets.
3. Use a valve compressor to remove the eight valves
(Fig. 66).
4. Use a hammer and drift to remove the swirl chambers
from the injector orifices, if necessary.
NOTE: Swirl chambers do not need to be removed
unless cylinder head is to be machined or replaced.
5. Clean the cylinder head. Use a wooden scraper and
gasket stripping solvent to clean the gasket face. DO
NOT use a metal scraper.
6. Check the gasket face for bow (flatness). Check
corner to corner and side to side (Fig. 67).
Maximum bow: 0.7 mm.
7. Check the condition of the valve seats and guides,
valve, valve springs, swirl chambers, camshaft, cam-
shaft bearings and all tapped holes. (See Identification
and Specifications section.)
