Gasket Reuse and Applying Sealant
| • | 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 specified in the service procedure. |
Separating Components
| • | Use incorporated pry points to separate components using an RTV sealing system. |
| • | Do not try to separate RTV sealed components by prying against other engine components. |
| • | Pry points are positioned so no other vital engine components are damaged when they are used. |
Cleaning Gasket Surfaces
| • | Use care to avoid gouging or scraping the sealing surfaces. |
| • | Use a plastic or wood scraper in order to remove all the sealant from the components. |
| | Do not use any other method or technique to remove the sealant or the 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 engine oil. |
| - | This fine grit is an abrasive and can cause internal engine damage. |
Assembling Components
| • | Assemble components using only the sealant, or equivalent, that is specified in the service procedure. |
| • | Sealing surfaces must 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. |
| • | Apply only the amount of sealant specified in the service procedure to a component. |
| • | Do not allow the sealant to enter into any blind threaded holes, as the sealant may prevent the fastener from clamping properly or cause component damage when tightened. |
| | Important: Do not overtighten the fasteners.
|
| • | Tighten the fasteners to the proper specifications. |
