I was putting the oil cooler studs back in all all is well until the last one. Going in nice and smooth. Bring out the wrench and half way in it binds. Okay, I'll back it out. No problem. Ha!! It don't come out. Takes a pair of vise-grips and a lever to get it out. Guess what? Mangled stud and case!!!
Got a WTB in the classifieds.
