2. Remove upper seal half from cylinder block.
3. Dip upper and lower halves of new seal in engine oil. Remove Oil seal retainer pin from bearing cap and discard. Install upper seal half in cylinder block so that 3/8" protrudes below parting surface.
4. Tighten remaining bearing caps to specification. Install lower half of seal in rear main cap so that 3/8" protrudes above parting surface. Apply light coat of oil resistant sealer to rear of top mating surface of bearing cap. Torque cap to specification, install oil pump and oil pan.
