Replacing Engine Gaskets

Replacing Engine Gaskets
Gasket Reuse and Applying Sealants
^ Do not reuse any gasket unless specified.
^ Gaskets that can be reused 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 the proper prying points to separate components.
^ Use caution when separating all RTV sealed components.

Cleaning Gasket Surfaces
^ Remove all gasket and sealing material from the, part using the J 28410
^ 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
^ 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.
