28. Cylinder
head
NOTE
Make a final visual check of the compression gaskets and seals to ensure that they
are in place before the cylinder head is lowered. This is a very important check.
Gaskets and seals which are not seated properly will cause leaks and "blow-by"
and result in poor engine performance and damage to the engine.
1. Apply a small amount of
International compound
No. 2, or equivalent,
to the threads and under-
side of the head of all
cylinder head attaching
bolts (1).
2. Wipe the bottom of the
cylinder head clean.
Then lower the head
over the guide studs.
3. Then install a bolt
through each piloting
sleeve at the corners
of the head and thread
them finger tight into
the cylinder block.
Continue to tighten
these bolts (finger
tight) as the head is
lowered into position
on the cylinder block.
NOTE
Cylinder head bolts are especially designed for this purpose and must not be
replaced by ordinary bolts.
