Lots of 91's will crack the thrust bearing on the crank, does it look like a piece of wear meaterial?
 
She need surgery. Tear her apart and if its the thrust check it out good. A set of main bearings might get you to 500,000 miles.
 
Had a small sliver on my drain plug too but not nearly as big as this. Why do the 91s crack thrust bearings?
 
Ya what is it caused by the truck has been stock all it's life is it just a manufacturing issue
 
The punctuation all fell out of the drain plug so he has non left.
 
Mine had .120 end play and this on the plug.
