### 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.
