Oil Seal
When rebuilding a Slant Six, the seal you will install is the main seal. There are two main seal types one is the rope seal and the other one is a brand-new rubber type lip seal. The rope seal has to be packed to the receiver groove in the seal cap and the cube. A piece of 2 3\/4 inch round tube makes a good tool for packaging the seal in that the grooves and that the cap can be set up over this tool to inspect seal alignment. Any rope fibers must be cut away from the surface where the block is met by the seal cap. 

Since most of gasket sets we'll show that kind is installed. All the related gaskets, their installation \/ positions are the same for both types of main seals. Note that the lower seal cap holds two cap and the seal to block rubber side seals, shaped like a L. The kind is groove so the side of the lip is currently facing into the inside of the engine. The sloped or angled side faces outward. Check to be sure that the seal halfs and paint mark the sides to assist with reinstallation. One trick I use with these hard rubberized lip type main seals is to compensate that the two halfs in that the grooves somewhat. 

This helps that the seal halfs self align by overlapping to the coupling groove, this also prevents the dividing lines of the principal seal and that the cap from being on that the exact same plane. The side L seals are installed utilizing a small amount of silicon sealer, this not only helps them seal, but additionally helps you slip the assembly to place. This view of the rear principal seal cap shows that the side that faces outward. When the cap is set up correctly, you may see the heads of the principal seal cap bolts from the outside the engine. 

Remember into apply a small amount of oil or assembly lube on that the seal's lip and turn the surface before the final installation. Once the main seal \/ cap is in place, I always clean the protruding L tab ends and completely match the surface completely, then glue these tabs down with weather strip adhesive or rubberized cement. This prevents that the tab from slipping out from under that the cork oil pan rail gasket. Make sure into allow yourself time into let that the adhesive dry prior to installing that the oil pan. With the main seal set up and the tab adhesive drying, now it's time to put in the timing chain cover. Always inspect for dimpled bolt holes and burrs.
