Interesting, I thought the 3.1 had kind of a bad reputation (head gaskets and intake manifold leaks)Same thing with a GM 3.1 in a oldsmobile. I had worked in a GM dealer while in college, and all the GM mechanics there said it was the most reliable engine GM made - even better than the 3.8 according to them. Again, I had zero problems, but the car fell apart around it - again no salt.
