- Use a gasket scraper to clean the cylinder head and cylinder block gasket surfaces. Do not scratch or gouge any surface.
- Do not use any other method or technique to clean these gasket surfaces.
- Clean the old sealer/lube and dirt from the bolt holes.
- Clean the bolt holes with a nylon bristle brush.
- When cleaning the cylinder head bolt holes use a suitable commercial spray liquid solvent and compressed air from an extended-tip blow gun to reach the bottom of the holes.
- Remove any broken long cylinder head bolts using the EN 38188 kit.
