Check the rod and bearings for any burs. I's start with fresh bearings to be on the safe side.

How shit measures is one thing. How it fits together is another.

I'm going to go out on a limb here, but he cannot move the rod on the crank the plastigauge is going to read 0. LOL

Sounds like you have the wrong bearing set esp. if the numbers don't match.

Didn't you put new rod bearings in this engine?

The connecting rods are 38ftlbs, not 32...at least according to the latest GM service info.

• Install the connecting rod bolt nuts.
Tighten

• Tighten the connecting rod bolt nuts to 52 N·m (38 lb ft).
• Loosen the connecting rod bolt nuts 1 full turn.
• Tighten the connecting rod bolt nuts to 52 N·m (38 lb ft).

That 38 figure, is it for the 4.3 or the 2.2?

2.2l

I'm not sure but it probably varies from year to year doesnt it? or is that just across the board from 94-03's models?

if it makes any difference, mine is a 96, and my manual was purchased within the last few months. not a factory manual though, so its entirely possible that my specs ARE outdated.

That is what GM says for 1996MY 2.2L in the Sonoma. I would just put it at 38. 6lbs isn't going to make a difference, but I would not put rod caps loose.
