    My 95 Eldo is still great. I joined this forum in 03-2006 and no
    cooling system issues at all. Some of you guys may remember
    me. I gave the Eldo to my wife. Now I drive a 1994 E420 Benz.

    I have an 03 DTS with a little over 88,000 miles on it. No problems yet, but after reading all of this I am afraid to take it out of the driveway.

    Where the hell have ya been? Yes it was noticed you were missing. I was trying to figure out how we could start an additional poll to show all of the cadillacowner's forum members who own/owned a N* before they moved on to state if they've had a HG issue or not. How do we let all of the lounges know?

    re: Northstar Headgasket/Cracked Block/Bolt Failure? Please let us know

    My failure was a 96 block, it was pressurizing the coolant system very badly and overheating as well.

    It got enough coolant in the crankcase that I spun bearings taking off from a stop light. Wierd thing was the oil never ever looked milky but when I drained it there was about a quart or so of dex in there then oil.

    I have a feeling it lifted the head because all the motor seen was WOT racing. It had about 15xxx on the fresh rebuild.

    Here I come headstud kit!!!

    94 Seville, 105,000. Loved the car but once the head gaskets go you are looking at serious money and you don't want just anyone doing the
    work. I've had 2 92's (4.9), 93, 2 94's, a 97, 98, and a 99. Only had one problem and that was the 94. Would love to know why.

    Unhappy re: Northstar Headgasket/Cracked Block/Bolt Failure? Please let us know

    I am in need of some help!!!

    My 99 STS has just started to overheat. Had a new thermostat installed and the car overheated again. Local mechanic confirmed a "head gasket issue."

    2 CADILLAC DEALERSHIPS REFUSED TO SERVICE THE CAR!

    I am in college so I don't have access to loads of cash; however, the car only has 117k so I don't want to junk it. Does anyone have any advice?

    2000 Deville 144500 not fixed yet can't say if it's the bolt failure or not.

    re: Northstar Headgasket/Cracked Block/Bolt Failure? Please let us know

    i got a question? when the head bolts pull out of the threads,. are their any threads left? what i mean is i noticed they give you a choice on new head bolts getting them longer, has anyone heard of someone putting in longer bolts and it holding the heads down? just curious,

    re: Northstar Headgasket/Cracked Block/Bolt Failure? Please let us know

    So for those of you who have sold or bought a 97-99 Deville with a blown gasket, what is the market bearing?

    My mom and dad have a 97 and gaskets are still good, factory installed Dexcool is still in it, and 110K miles. It recently got a little low, but just in the resovoir. That is it. So wondering if they would even get much with a good gasket, but all OEM? Mom wants a newer 2000-up Deville....

    re: Northstar Headgasket/Cracked Block/Bolt Failure? Please let us know

    I have a 2003 DeVille DTS with a bad head gasket at 62000 miles. No warning, just started leaking coolant. It's blowing pressure back into the surge tank. It still runs perfectly fine, but I go through about a gallon of coolant every other day. Unfortunately it's all I have to drive. I was going to sell it, but the value fell so fast I'm about $5000 upside down in it and can't afford the head job.

    Sorry to vent. lol
