WARNING
Do not scrape the joint faces of the aluminium,
any damage caused to the joint face will result in
a risk of leaks.
WARNING
Do not allow this product to dr ip onto the paint-
work.
Clean the cylinder head carefully to prevent for-
eign bodies from entering the oil supply and
return galleries.
Failure to follow this advice could lead to the
blocking of the various oil inlet galleries, which
would quickly result in engine damage.
WARNING
Protect the oilway so that foreign bodies do not
enter the oil pipes in the cylinder head.
Failure to follow this instruction could lead to the
blocking of the oilways, resulting in a rapid deteri-
oration of the camshaft.
Note:
The cylinder head bolts must not be lubricated
before being fitted.
WARNING
No regr inding of the cylinder head is permitted.
