2001 Cadillac DeVille from North America
Great car; I blame the dealership and manufacturer :-(
The major thing, is really big. It was leaking oil, it was on my garage floor, it was an ongoing thing. I took it to the dealer I purchased it from; they told me $4,600.00 to repair a blown head gasket, and I was told not to drive it as it could catch on fire. My husband had recently passed, I went home totally depressed. I called Cadillac with no results whatsoever.
I took to other reputable mechanics; it was not the head gasket, it is a fault in the Northstar engine. It did use a lot of oil (about 1 quart per month). The kicker to this is the dealership charged me $50.00 dollars for the diagnosis. I did sell the car with full disclosure of my problem. I had to sell cheaper than if in good condition.
I failed to mention that I called Cadillac many times. I was told by a supervisor that it is old anyway. Wow.
Would you buy another car from this manufacturer? No

I currently own a 2002 Deville with 72K miles. Bought it as a certified car in 2005. It uses a quart of oil in 1K miles. Supposedly normal. Otherwise, it's a great car. If it was driving well, I would not have sold it. Just add oil as needed.

Thank you for the info. Have the same problem. You are correct, it is a badly designed engine; all of them will develop the same problem! You can't just replace the head gasket; the head bolts will come loose and will come out with the threads!!! All of Northstar engines will do it around 90K miles. Well... welcome to the club. Never again will I buy a car with a Northstar engine. NEVER!

Northstar engines aren't the kind of engines that one can repair/rebuild. They're too complex. If something goes bad on them, the entire engines have to be tossed and completely replaced.

This guy seems to know how to rebuild them.
