Reinstallation

Make sure that the engine block surface is
perfectly clean.

Using a dial indicator gauge with a magnetic
base, check pistons height, to specify the
cylinder head gasket.

There are available 3 (three) types of gaskets
for the cylinder head assembly, identified by
holes in the left side, from front viewing.

Note:

Cylinder head gasket corresponds to piston height, in relation with cylinder head
surface.

Select a new gasket with the correct
thickness.

position.

Check bolts deformation with a flat ruler,
checking their lengthening 1, diameter
reduction 2 and whether there is visible
waste in the threads 3. If one of the last 3
parameters is out of their project features,
they must be replaced.

Apply some lubricant oil on bolts threads and
install them in the indicated position:

10. Tighten bolts until their heads touches the
