Do not re-use any gasket unless specified in the service procedure. Gaskets that can be re-used will be identified within the procedure.

Do not apply sealant to any gasket or sealing surface unless instructed in the service procedure and if instructed, use only the recommended sealant or the equivalent as stated.

Remove all gasket and sealing materials from aluminium components using a plastic or wood scraper. Do not use any other method or technique to remove sealant or gasket material from a part. Care must be used to avoid gouging or scraping the sealing surfaces.

Do not use abrasive pads, sand paper, or power tools to clean the gasket surfaces. These methods of cleaning can cause damage to the components sealing surfaces. Abrasive pads also produce fine grit the oil filter cannot remove from the oil. This grit is abrasive and can cause internal engine damage.

When assembling components, use only the sealant specified or equivalent as recommended 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 this can cause the bolt to bottom out and prevent it from clamping properly or cause component damage when tightened. Sealing surfaces should be clean and free of debris or oil.

Specific components such as valve stem oil seals may require lubrication during assembly. Components requiring lubrication will be identified in the service procedure.

Ensure all fasteners are tightened to the correct torque specification.
