Removal and Installation of Cylinder Head Valve Cover for 1998 Cherokee 4WD L6-4.0L VIN S
Valve Cover: Service and Repair
Cleaning and Inspection
CLEANING
Remove any original sealer from the cover sealing surface of the engine cylinder head and clean the surface using a fabric cleaner. Remove all residue
from the sealing surface using a clean, dry cloth.
INSPECTION
Inspect the engine cylinder head cover for cracks. Replace the cover, if cracked. The original dark grey gasket material should NOT be removed. If
sections of the gasket material are missing or are compressed, replace the engine cylinder head cover. However, sections with minor damage such as
small cracks, cuts or chips may be repaired with a hand held applicator. The new material must be smoothed over to maintain gasket height. Allow the
gasket material to cure prior to engine cylinder head cover installation.
