Be careful not to damage the contact surfaces of the cylin-
der head and cylinder block.
HINT:
If the cylinder head is lift off, pry between the cylinder head and
cylinder block with a screwdriver.
67. REMOVE CYLINDER HEAD GASKET
68. INSPECT CYLINDER HEAD SET BOLT
(a) Using vernier calipers, measure the tension portion diam-eter of the bolts.
Standard outside diameter:
10.75 to 11.00 mm (0.4232 to 0.4331 in.)
Minimum outside diameter: 10.40 mm (0.4094 in.)
If the diameter is less than minimum, replace the bolt.
69. INSTALL CYLINDER HEAD GASKET
(a) Measure protrusion height of the piston heads. (1) Clean the cylinder block with solvent.
(2) Set the piston to be measured to slightly beforeTDC.
(3) Place a dial indicator on the cylinder block, and cali- brate the dial indicator at 0 mm (0 in.).
HINT:

Place measuring tip of the dial indicator as shown in the
illustration.

Make sure that the measuring tip is square to the cylinder
block gasket and the piston head when measuring.
(4) Find the most overhung position of the piston head by slowly turning the crankshaft clockwise and
counterclockwise.
