&$87,21
When removing the cylinder head gasket, be careful
not to damage the cylinder head or crankcase surface
by tools such as a screwdriver.
(1) Remove the cylinder head bolt.
(2) Remove the cylinder head assembly by lifting it up.
Note: If the cylinder head assembly cannot be removed due
to crimping of the cylinder head gasket, tap the thick
area on the side of the cylinder head using a plastic
hammer to give a shock.
(3) Remove the gasket from the cylinder head.
Note: If there is a cylinder head problem, check the bolts for
tightness with a torque wrench before removing the
cylinder head bolts.
