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.
