REPLACING ENGINE GASKETS
Tools Required
J 28410 Gasket Remover. See Special Tools and Equipment .
Gasket Use and Applying Sealants
Do not use any gasket again unless specified.
Gaskets that can be used again are identified in the service procedure.
Do not apply sealant to any gasket or sealing surface unless called out in the service information.
Separating Components
Use a rubber mallet to separate components.
Bump the part sideways to loosen the components.
Bumping should be done at bends or reinforced areas to prevent distortion of parts.
Cleaning Gasket Surfaces
Remove all gasket and sealing material from the part using the J 28410 or equivalent. See Special Tools
and Equipment .
Care must be used to avoid gouging or scraping the sealing surfaces.
Do not use any other method or technique to remove sealant or gasket material from a part.
Do not use abrasive pads, sand paper, or power tools to clean the gasket surfaces.
These methods of cleaning can cause damage to the component sealing surfaces.
Abrasive pads also produce a fine grit that the oil filter cannot remove from the oil.
This grit is abrasive and has been known to cause internal engine damage.
Assembling Components
NOTE:
Refer to Sealant Notice in Cautions and Notices.
When assembling components, use only the sealant specified or equivalent in the service procedure.
Sealing surfaces should be clean and free of debris or oil.
Specific components such as crankshaft oil seals or valve stem oil seals may require lubrication during
assembly.
Components requiring lubrication will be identified in the service procedure.
When applying sealant to a component, apply the amount specified in the service procedure.
Do not allow the sealant to enter into any blind threaded holes, as it may prevent the bolt from clamping
properly or cause component damage when tightened.
Tighten bolts to specifications. Do not overtighten.
