I ran into this problem also. My shop used oversize actually thicker shelled bearings and align honed,Bored them to fit the cam. Iwas was a head ache as he had to make the fixture and alignment bushings but its going on 2 years service and all has been ok ! He did at first talk about junking the block but since It had already been fully machined and made ready to assemble we fixed it. It cost me another 200 bucks though ! I talked to a few Pontiac Gurus and it seems this is not to uncommon and one told me he used an old cam with cuts in the bearing journals as a cutting tool to clearance the bearings. Good Luck

What 77TA said at the end.
I have a tool I made. This is an on going problem with Pontiacs. They have such a weak main bearing area and the center of the block (cam area) moves around. Ya gotta do what ya gotta do. Bet it was #2 huh?  [ June 12, 2002, 07:54 AM: Message edited by: PONTIAC DUDE ] |

Take a look at the cam area. I had a guy breaking down core motors for me at one point in time, that would tighten the cam bearing tool very tight when removing them. This would score the cam area, kind of like knurling valve guides.In effect reducing the bearing area size. This crimped the bearing onto the cam and the result no turning this one. Had to take a dremel tool to the high spots and rebearing the block. Unfortunatly he did about 30 or so before the first one came up to build and the problem was discovered. Good luck Julian

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.
