I just pulled the heads off & the cylinders on the left bank are scratched on the bottom side,Very light but scratched,Cant see no damage to rings,gaps wernt close to scratches,Any IDEAS to what caused this?Also pulled the rod & main bearings & they "Most" have lost all the babbett is this normal,Also have light scratches on journals?I put this eng together Xtra clean,the rt bank looks ok.eng was quiet on startup,Reason i pulled eng "I thought i had blown the HG,They are good,had flutter like a card on a spoke wheel under boost,looks like a good hone job would cleanup cylinders.This eng only has 3500-4000 mi on it??Should I have crank turned or is this normal?
