Although our rear main seal was in good shape, the replacement procedure is to remove the rear main bearing cap and thread a wood screw partially into the seal half that's in the block. Yank it out with a pair of pliers, then lube the new seal half with engine oil and slide it back in the bore. It seems daunting, but it always goes easier than we think it should. Replace the other seal half in the bearing cap and then retorque to factory specs. When installing the pan gasket, we only use a dab of RTV at the corners of the pan gasket and where the rubber and cork gaskets meet. Otherwise, we coat both the gasket and mounting surfaces with Permatex Aviation Form-A-Gasket sealant or Edelbrock Gaskacinch. Don't gun down the pan gaskets more than 12lb-ft, or it can crush the gaskets and cause a leak.
