CLEANING
To ensure engine gasket sealing, proper surface preparation must be performed, especially with the use of aluminum engine components and multi-layer steel cylinder head gaskets. Refer to Engine/Service and Repair/Procedures/Standard Procedures/Engine Gasket Surface Preparation. See: Service and Repair\Procedures\Engine Gasket Surface Preparation

NOTE : Multi-Layer Steel (MLS) head gaskets require a scratch free sealing surface.

Remove all gasket material from cylinder head and block. Be careful not to gouge or scratch the aluminum head sealing surface.
Clean all engine oil passages.

INSPECTION

1. Cylinder head must be flat within 0.1 mm (0.004 inch) (Fig. 15).
2. Inspect camshaft bearing journals for scoring.
3. Remove carbon and varnish deposits from inside of valve guides with a reliable guide cleaner.

1. Using a small hole gauge and a micrometer, measure valve guides in 3 places top, middle and bottom (Fig. 16). Replace guides if they are not within specification.

1. Check valve guide height (Fig. 17).
