Replacing Engine Gaskets

Replacing Engine Gaskets

Tools Required

J 28410 Gasket Remover

Gasket Use and Applying Sealants

^ Do not use any gasket again unless specified.
^ Gaskets that can be used again will be 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.
^ 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

Notice: Refer to Sealant Notice.

^ 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.
^ Tighten bolts to specifications. Do not overtighten.
