Well, I'm learning slowly.  

I was staring at the crank shaft sitting on the dining room table (yes, I put 
newspaper down!), while commenting to myself, "Gee, isn't it interesting that 
the crankshaft surface where the rods attach is completely smooth, and where 
the main caps go the crankshaft has all these ridges and grooves ---  a few 
more minutes of staring and I begin to think -  "Wait a minute, the grooves 
where each main cap goes are different at each location on the crankshaft -- 
what gives?

Yep, the parts of crankshaft where the mains attach are full of ridges and 
grooves, so much so that when I first looked at it I figured this was 
normal!....  The grooves are so bad that there is an inverted version of the 
oil groove in the bearings on the crankshaft as well, and I thought that was 
normal too....

So, with that much wear, something went wrong somewhere at some point.  
Ideas?  And why would the parts of the crank that attach to the rods look so 
good, and the place where the mains attach look so bad?

Anyway, I may very well be in for a new crankshaft.  So, anybody got one on 
the cheap, or know where I can get one on the cheap?

As usual, thanks!
