This may be nothing you can help with, however the northstar engines made by gm have had a defect for many, many years. There are no records that you have checked into the problems with this. It regards the head gaskets breaking at an alarming and consistent rate for the past 10 years! Ask any mechanic about this. Around 100,000 miles on the engine the head gaskets break, and coolant leaks into the engine. No one will replace the gaskets. All you can do is spend a small fortune ($5,000 to $9,000) on a new engine. A waste of money since the next northstar engine will probably do the same thing. This is something that gm knows about and continues to ignore. No wonder they are going out of business. After 100 years they still cannot produce a reliable engine! If you expect americans to continue buying american cars, especially cadillacs, please do some research on this. You can find letters written by seville owners on the web about this. I am most certainly not the only one, just one of many, many lemon owners. Hoping you care enough to have listened and check this out, sincerely

Northstar engine problem - the head bolts pulled loose causing engine coolant to leak into the exhaust. Had inserts put in by local mechanic who had previously done two such repairs (cadillac advised that it only had a 60% chance of fixing the problem if they did the work and the cost would be $3,000 - $4,000). Car had about 70,000 miles on it at time of failure. Car ran well until october 2008 when coolant loss started again. Have tried various sealant but it is likely the head bolts again. An aluminum block with aluminum heads and high compression appears to be combine with a weak design of the head bolts. From what I hear all northstar's of this era will have this problem at some point and the problem was not fixed until 2001 or so. It is said that a jeg's motor has addressed this problem but at a cost of what, $3,000 plus installation? I like the car but it is hard to work on and has its share of issues.
