If you're loking for something in a bottle to ease your problem, may I suggest "Duggan's Dew of Kirkintiloch".

I have a 1993 eldorado that has a small leak of carbon gasses into the radiator, a sign of a blown head gasket. No coolant in the oil, only overheats if you drive it hard. Does anyone know if thermagasket will work on the northstar engine, blue devil and steel seal say not to use it because of the wet sleeve that engine has. The dealer wont even replace the gasket because they say it wont last. Any suggestions will be appreiciated.

Do a search. NO repair in a bottle will work. IF repaired properly (with Timeserts) it will last.

The dealer is full of s##t.

Guys are doing them at home and they work. It's a long job though.

Fiddlertom, why don't you indicate where you're located. Guys that have had it done might be able to suggest a shop.

Wife has 98 Deville
Cars been overheating on and off for 9 months
Changed water pump ,radiator , thermostat
presurized each cylinder no signs of leakage other than overboard thru coolant tank
tried everything to the tune of $1000.00

head gasket finally let loose, had them do the timesert job also $3500.00
Engine now runs at a steady 200F +/- 3 NO MATTER WHAT YOU RUN THE CAR AT

End it and Pay the money

Does that Blue Devil fluid work on Northstars? Just blew head gasket in 1997 Concours with 72,000 miles

No snake oil works. There is only one way to fix it.

Not only does it not work, you will have problems with a clogged cooling system after you replace the head gaskets.

I'd tell him to keep the car. "The blown Headgasket thread" has over 11,000 veiws, 2nd on the list here. Its clear that this N* motor is a complete piece of shit. I'm dealing with the same thing right now on my 97 SLS Seville. What a joke. If I'd of found this forum prior to the purchase, it never would have happened. Some poor stupid ******* paid almost 50k for this peice of shit that I bought just over 11 years ago. I bought the junk pile for 2k and its not worth that. lol What a complete joke. Id get rid of it.

Like it or not, by the numbers, Northstars can't hold a candle to the reliability of an LT1 let alone many other V8s. How many high-output aluminum V8s out there do you see with the kind of failure rate of the Northstar head gaskets? Answer, NONE.
If Cadillac customers would STOP taking it on the chin and smiling about it, Cadillac would be FORCED to improve their product. Like it or not, Cadillac aluminum engines have cost them a HUGE amount of money and customers over the years.

Great post, its just amazing, breathtakeing, how people bend over and let Cadillac shuv it in deap...amazing...IMHO the N* is a complete pile of shit. I'm amazed people would spend 50k+ on a car thats going to be worth less then 10k after just 70,000 miles, lolol Amazing. Over 100,000 miles and your talking 3 or 4k. What a joke.

As long as they can get away with it, they will.lol Ever wonder why GMs stock has decreased so much? lol
