u/Feisty_Inspection_96

Connecting Rod bearing #2 got spun and had some deep scratches on its journal, I decided to replace the crankshaft because its severely out of round. The new crankshaft measured: (using green plastigauge):

Connecting Rod tolerance: (all old bearings except #2)

1. 0.001" (0.025mm) (a bit less)
2. 0.001" (0.025mm) (new bearing)
3. 0.001" (0.025mm)
4. 0.001" (0.025mm)
   Service manual: 0.00138"-0.00232" (0.035-0.059mm)

Main Journal tolerance: (all old bearings)

1. 0.001" (0.025mm)
2. 0.002" (0.051mm)
3. 0.001" (0.025mm) (a bit less)
4. 0.001" (0.025mm)
5. 0.0015" (0.038mm)
   Service manual: 0.00055"-0.00146" (0.014-0.038mm)

My thoughts:

1.) I am suspecting Main Journal #2 has too much tolerance causing less oil flow into Conrod Journal #2 - is this correct?
2.) I noticed the specifications had a slightly tighter tolerance on the main journals than on the connecting rods, but with this new(old) crankshaft, this new one I got has the Main journals in range, but the conrod journals looking a bit tight - is this going to be ok?
