hey guys, wanted to start a discussion about main bearing failures. I recently finished the break in period on my new motor and noticed some odd increase in knock count and lower then normal oil pressure. Finally got the heart to open the pan and look at the bottom mains. two of them were flattened and expanded outward. The shop that build the motor said it was caused by excessive amounts of boost and or detonation. I myself have never seen mains flatten out like this. I never pushed the motor past 15psi and the AFR was never more then 14ish during the break in period. Any advice or perspective would be appreciated.
