Just took apart my 20k mile 400whp ej22. All the bearings were worn almost the same. Main #5 being the worst. I don't think it was about to blow but there was excessive glitter in oil so I took it apart anyway. Im going to put blame on myself being a cheap ass and not line honing and reusing a crank that could have been polished better. The pan and everything was clean. Oil just kept comin out with glitter so it was just wearing quickly I guess
