Scuffs on Piston Skirt
So I got my slant torn apart a few days ago in anticipation of getting the block sent out to check if everything's good. I was prepared to see some damage to #3 due to oil on the spark plug and lower compression than the other cylinders when it was running. (150 in everything, then I think 110-120 in #3) Head has already been rebuilt and shaved .030" and placed back on the car, then the blue smoke happened.
Checked everything, bearings are okay. Camshaft good. Head gasket fine. No obvious broken rings on #3, but #2 piston had this on both sides right next to the wrist pin location:
The actual cylinder looks very normal, no scratches or anything. Nothing enough to catch my fingernail on the skirt. Should I be concerned? Get new pistons? I have not been able to check roundness of cylinders yet. Thank you
