ReferenceDisassembly and Assembly, RENR8628, "Cylinder Head - Remove" Disassembly and Assembly, RENR8628, "Cylinder Head - Install"If the gasket is not damaged, the existing 227-1204 Gasket can be used.
Remove the cylinder head.
Remove all previous material from mating surfaces.
Clean all surfaces and dry all surfaces with a solvent that is free of residue.
Remove the cap and apply the 4C-9505 Gasket Sealant with the applicator to the surface of the gasket that will contact the engine block. Note: Loctite 5923 or Permatex Aviation Form-A-Gasket No.3 Sealant can be used as alternative sealants.
When the sealant is used as a dressing for the gasket, spread the product with a spatula to a uniform film on the surface of the gasket that will contact the engine block. Ensure that the gasket sealant is spread evenly over the surface of the gasket. Position the gasket on the cylinder block.
Install the spacer plate over the gasket that is located on top of the cylinder block.
Install the gasket that was located between the spacer plate and the cylinder head over the spacer plate.
Install the cylinder head.
Once the repairs have been completed and the sealant has cured, run the engine in order to ensure that there are no leaks.Cleanup
The sealant can be removed from metal surfaces with isopropyl alcohol. If the sealant has been dried for a long time or at high temperatures, cover the sealant with alcohol and allow the sealant to soften overnight.
Clean hands.
