thrust bearing damage
mylittlecj5
RIP Mike, we'll all miss you
what would cause a thrust bearing to wear on one face?
its been a while since ive rebuilt an engine, and this is my first Amc.
when i tore this one down over the weekend, i saw the crank had a lot of endplay. then i found metal slivers in the oil pickup screen. when i removed the number 3 main cap, the thrust bearing was visibly worn on the forward side, lower bearing half.
the others are worn, but not nearly as bad as this one.
What would cause this condition? driving habits, oiling problems, ect?
engine is a Amc 360 out of a late 80's wagoneer DD/off road truck.
