It's ugly

I removed the oil pan to check the bearings and that half-moon shaped piece of metal was staring up at me. It's a thrust washer, which is used to adjust the amount of endplay in the crankshaft.

This is what the crank looks like when it has been pushed forward too much.  The crank got pushed into the bearing support so hard that the crank now has a groove where there's isn't supposed to be one. See that little bit of metal sticking out where the crank meets the support? That's what's left of a metal washer.

And here's a fuzzy picture of a main bearing-it's cooked. The connecting rod bearings look the same. What caused all this destruction is a transmssion shaft that is slightly too long and forced the cranshaft forward. This caused friction between the crank and bearing support. This may have caused the overheating and power loss.
