Cadillac Repair: cadillac deville, blown head gaskets, 2 quarts

Question
thinking about buying a 1997 cadillac deville with 128,000miles.  Northstar engine......good buy?
What should i expect with this car

Answer
Hello,

I don't know if it is a good deal. You did not state price condition etc.

Northstar uses oil and cannot be overheated. These engines suffer from the normal problems of over heating due to a cooling system problem however, when and if this occurs, people commonly tend to run these engines hot until they get repaired causing catastrophic engine damage like blown head gaskets and worse.

Just be aware of these issues.

Where the oil goes I have no idea, but I have seen these engines use 2 quarts in 500 miles without smoking.
