What kind of tolerances am I looking for between wrist pins and the rod sleeves? With 6 of my Manley forged rods the pins slide in nice and tight. One slides in easily and one slides in almost loosely. I'm concerned about the two looser ones. They're all factory used SVT rods. The two in question are from another motor. The 6 are from the same set. Should I get new sleeves pressed in??
