That Sneaky Pete tool is for the old rope seal of the 50s - 60s.. Not for the modern 2-piece neoprene seal.. Loosen (but don't remove) all the other main cap bolts except #1. About 1/8" is all that's needed. Use a small brass punch to get the old seal started moving. Once the upper half is in place, re-torque the main cap bolts previously loosened. Install the lower seal half. Don't use any sealant anywhere on the seal pieces. Put a very small "dot" of sealant on the block in the rear main cap recessed "seat" area between the upper seal half and the end of the pan gasket. Install and torque the rear main cap. This procedure is referenced in the Engine (section 6) section of the Factory Service Manual.
