Alright, my friend says that on his way back from Oklahoma, that his truck was having trouble going up hills and that it finally got real hot and died, so they check everything and it was "out" of oil (I know its sad) and that smoke was coming from every open hole on the motor, so they left it. They came back about 4 hours later and filled it with oil and drove for about 15 minutes and then the oil pressure dropped to zero and the temp. climbed to about 270, so he shut it off but, it didn't spin down, it just stopped. This is an '87 Chevy Pickup with a 350 and about 210,000 miles on the motor. I was thinking a spun bearing, but don't know, what do you guys think?
