Connecting rod squirt holes?
Well, that's right, there is only one gap per pair. I was pushing each pair to the right, measuriing the gap on the left, and then vice a versa. In other words, the gap for each pair varied between .014" and .025", depending on which side of the crank journal i was using. Actually, I don't see why the measurement can't just be taken between the rods themselves, which is what I was also trying and the result was pretty much the same.
