Remove oil pan bolts. Remove oil pan using a rubber hammer if
necessary. Remove sealant residue from cylinder block and oil pan.
Ensure surfaces are free from grease and oil.
         2) To install, apply 2-3 mm thick silicone bead around
sealing surface of oil pan. Immediately install oil pan and lightly
tighten all bolts. Ensure oil pan is flush with cylinder block.
Tighten bolts to specification. See TORQUE SPECIFICATIONS. To complete

         OVERHAUL

         CYLINDER HEAD

         Cylinder Head
         Clean all gasket mating surfaces. Check cylinder head for
warpage. Ensure warpage does not exceed .0039" (.100 mm).

         Valve Stem Oil Seals
         With valve springs removed, remove oil seals using Valve Seal
Remover (3047A). To install new oil seal, slide plastic sleeve over
valve stem. Lubricate new oil seal. Using Valve Seal Installer (3129),
push oil seal on valve guide.

         Valve Guides
         1) Check valve-to-guide clearance specification. See
CYLINDER HEAD table under ENGINE SPECIFICATIONS. If valve guides have
previously been replaced, replace cylinder head.
         2) To replace valve guide, press guide out from camshaft
side. Lubricate guide and press in cold cylinder head (from camshaft
side) until shoulder makes contact. DO NOT exceed one ton pressure.
Ream guides to proper valve-to-guide clearance. See CYLINDER HEAD
table under ENGINE SPECIFICATIONS.
