1. Check the inlet manifold for oil deposit and debris, and clean, if necessary.
2. Remove the gasket remnants from the cylinder head.
– Use only brass scrapers or brass brushes to clean the residual material on the head-to-block mating surfaces.
– Do not use steel brushes, steel scrapers, or polishing pads.
– The striations on the mating surface of the head and the corresponding surface on the block are part of the strategy for preventing gasket fretting and erosion. Do not polish these surfaces.
3. Remove any carbon deposit from the cylinder head.
4. Clean and degrease the contact surfaces of the cylinder head.
5. Check the cylinder head for damage.
