Those caps need to be fitted, period. They're going to walk. Have the caps trued and the block line bored, or you'll be asking for trouble. If it's out of the car and on the stand now, take care of it now, otherwise it'll be more trouble, headache, and work later...

From what I understand main caps should have no space beneath them. If there is a space and you have a correct torque reading then the caps are binding on something. You should not have to use the main cap bolts to pull the caps down, but they should be flush with the block.

Irrespective of the need to have the block aligned bored or whatever, the '61, '62, '63, and '64 PMD chassis books, the years I have, all say to run a line of sealant from the rope seal to the outer edge of the saddle to where the pan gasket goes. Therefore Pontiac did anticipate the possibility of oil leaking under that saddle.

61-63 - True on the sealant, but if there's a gap between the block & cap, it will trail out of there towards the back, unless you squeeze the rtv into it. Also, the bead should really only go from about the cap dowel back or so, where the pan/cap/block interface.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
