[PLAY400]

Tearing apart a 400 I had done but not run. Assembly was done by shop. I have what looks like sprocket marks, uneven scuffing (chatter) on my rod bearing and full scuffing on different sides of the mains. Not even across the surface but one side side of 1 bearing, other side of bearing on next journal etc. It's like the mains were polished on an angle.

To me the scuffing looks like the engine was put together tight. engine has not been run and was well oiled.

I have never put together a new rotating assembly nor torn 1 down before. What gives? Thanks Alan
