Question about 1989 Cadillac Sedan DeVille
If you have a HT4100 engine, the block is aluminum and the design is poor. It is quite possible that the main bearing saddles are out of alignment and that's causing your problem. That condition can only be corrected with an align bore which requires total engine dis-assembly. On an old vehicle, it is just way too expensive.
If you really want to keep the car, consider an engine upgrade but that too costs a lot.
I know that this isn't what you wanted to hear, but it is what it is...
