Thank you for the reply,you are very right,and I do agree with you,I am using lapping compound of various grits witch I clean,it's only on the journal itself,The hole is pluged so none gets in there.The failed because Mack reman center put standard rod bearings,in a crank that was cut 0.010,the mains are correct,so they are fine. There was no blueing or discoling of ant sort,it only ran for a few minutes after it failed.I alreadey cleaned the oil cooler,pressure wasing rinsing with solvents and compressed air.I want to flush with solvent through top of the motor first,then I will do the bottom with solvent under pressure moving the pistons and cam to diffrent positions,blowing it out and redoing it again until I feel it's alright,I will put break in oil in for the first few hours,then change it,and new filters of course,new oil pump to. what do you mean by "The galley will have metal in it till it is vatted" I don't get this could you Please explain this more so I can try and correct it. Thank You very much Paul I will take any help I can get on this,if anybody has some suggestions,I would love to hear it
