(7) Use a blunt screwdriver to remove the lower filler block seal (5) from the rear filler block (6). Discard the seal
(5).
b. Cleaning.
(1) Clean the mounting surface of the cylinder block with cleaning solvent. Use a blunt screwdriver to remove
gasket pieces and gasket sealer from the mounting surface.
(2) Inspect the mounting holes in the cylinder block and clean them with a small brush dipped in cleaning
solvent.
(3) Wash the oil pan in cleaning solvent and remove all sludge and dirt from the bottom of the oil pan. Wipe the
oil pan dry with a soft absorbent cloth. Clean residue of the old gasket from the mounting edge of the oil

Replace the oil pan, if the cracks or holes are excessively large.
e. Installation.
(1) Coat the new gaskets (1 and 2, fig. 40) and the mounting surface on the cylinder block with a fast-drying
gasket sealer.
(2) Install both gaskets (1 and 2) on the cylinder block and see that the mounting holes in the gasket and the
cylinder block are properly alined. Allow about 5 minutes for the gasket sealer to set.
(3) Install a new oil seal (2, fig. 41) in the rear filler block. Coat the seal lightly with engine oil and see that it is
seated properly in the groove on the filler block body (1). The proper oil seal installation method is shown in
