Ask any engine builder and they will tell you that this is essentially a new engine...I fully trust that this engine was re-manufactured with likely more precision and a higher quality control standard than that of the original engine that came off the assembly line...In fact, if it was not for the poor quality control standards of the original engine off the assembly then guys like me would have never had to worry about catastrophic bearing failure...
Then why did you make this thread? Obviously if they were as thorough as you state, then they should have known more than a non-engine builder like myself to check the main, and rod bearings, along with the pistons. So why ask if you should change your bearings?
