4. Remove the cylinder head gasket.
5. Use the following procedures to properly clean the
cylinder head and cylinder block surfaces:
• Use a kitchen soft scrub pad and ID Red to clean
the cylinder head and cylinder block gasket
surfaces. Do not scratch or gouge any surface.
IMPORTANT
Do not use any other method or technique to clean
these gasket surfaces. Do not use a tap to clean the
cylinder head bolt holes.
IMPORTANT
Be careful not to gouge or scratch the gasket surfaces.
Do not gouge or scrape the combustion chamber
surfaces. The feel of the gasket surface is important,
not the appearance. There will be indentations from the
gasket left in the cylinder head after all of the gasket
material is removed. These small indentations will be
filled in by the new gasket.
6. Clean the old sealer/lube and dirt from the bolt holes
with a stiff steel brush.
7. When cleaning the cylinder head bolts holes use a
suitable commercial spray liquid solvent and
compressed air from an extended-tip blow gun to
reach the bottom of the holes.
CAUTION
Wear safety glasses to avoid injury when using
compressed air or any cleaning solvent.
