Cleaning and Inspection Procedure - Conditional
Perform the following cleaning and inspection or overhaul steps, as necessary. ONLY perform steps when components are removed with the intention of reinstallation.
Refer to Safety Glasses and Compressed Air Warning .
When cleaning the sealing surfaces of engine components, DO NOT use bristle discs, abrasive pads, wire wheels or surface conditioning discs. These types of devices should not be used because they produce a very fine grit that is abrasive and known to cause internal engine damage. The bristle discs and pads are embedded with abrasive material and wear down as they clean, continually exposing fresh abrasive to the surface of the component.
- 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. 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. These methods of cleaning can cause damage to the component sealing surfaces.
- NOTE:
Ensure proper use of room temperature vulcanizing (RTV) sealant. Use of Room Temperature Vulcanizing (RTV) and Anaerobic Sealant
Clean the cover in solvent. Remove the sealant from the front cover to the oil pan surface.
- Dry the cover with compressed air.
- Inspect the gasket sealing surfaces (1) for excessive scratches or gouging.
- Inspect the threaded bolt holes (2, 3, 5) for damaged threads or debris.
- Inspect the camshaft position sensor pass-thru hole and sealing surface (4) for excessive scratches or gouging.
- Inspect the oil flow control valve connector pass-thru hole and sealing surface (6) for excessive scratches or gouging.
