Okay I know that my crank is pretty chewed up from oil starvation. The Harmonic balancer is also chewed up. The bearings are worst in the front and get better as they go back through the rods and the last rod and rear main bearings look like they just came out of the box. I have most of them off had to put the caps back on to turn the crank to get the pressure plate off. So how do I know if these need to be replaced. I heard that the crank may or may not be able to be turned due to the bearing areas only being so strong and so hard? I haven't pulled the cam so don't know the status of the bearings.
