    1999 DeVille Concours in excellent condition with 133K miles...gaskets blown...never overheated to date...exhaust in the coolant resevoir noticed after having to add one gallon twice in 230 miles...after sat a week now observe white billowing 'smoke' and smell out of both exhausts...the car doesn't have a scratch or ding...never wrecked...shines like the day she was new...driver's seat leather a bit worn and the headlight covers are sandblasted and need replaced, also the gas gauge quit (tank unit) but nothing else until the headgaskets...still doesn't overheat. Owned since new and serviced better than scheduled. I wouldn't complain if it was a 'normal' head gasket job as in $500-$1000 but between $4K and $8K+ dependent on route taken? Unbelievable. The northstar and the Seville STS brought back Cadillac and now leaves me and others stranded and frustrated...Nearly $50K new and 133K miles later essentially junk? What gives???

    Junk to others maybe but junk to you ? A head gasket job should cost between 2-3000 at 4-8000 I am thinking they are wanting to replace the motor ? Did you continue to drive it after you noticed the white smoke ? If so that would definetely kill the motor at least it did on my 99.

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

    Sorry about your HGs. Has anyone posted any info on the CTS/CTS-V lounges to let them know about this poll? I'm sure alot of them have upgraded and have not visited the older Caddy lounges. Most of you know that once someone upgrades why would they visite the Seville/Eldo/Deville lounges. We got good information going on about the HG problems so I see no way why it shouldn't flow thoughout the entire forum. Imput please. Thank you.

    96 Eldorado cream puff 72,000 miles. I drove this car for 5 years with very few minor repairs. I had no problems with loosing coolant or over heating. Then one day on my way home from work it it was running just fine until it started blowing white smoke, the temp shot off the scale and the diagnostics went Krazy so I pulled over immediately and called for a hook to haul it home. I haven't done anything with it yet because I've been having some health issues but plan on fixing it after I retire the end of June. Actually, the engine still runs smooth as silk but after a few minutes it starts blowing white smoke (still runs smooth) and there is coolant coming out the tail pipes so I'm sure it has blown a head gasket or maybe even two.

    Well folks, I'm #36 on the '99 poll.

    99 Deville, 96k miles. Blown HG. Replaced with Prestone Dexcool every 3 yrs to try to avoid this fate...

    Currently using it as a local car. To reduce overflow from surge pipe, I rigged an empty antifreeze 1 gal container to catch it and recycle it back in when the engine is cold. Works well to buy me some time to figure out what my options are. It has a 15 mile highway range with no traffic. Or 5-8 miles with traffic.

    I'm tempted to fix my baby. Done 90% of the work and maintenance myself. Still looks and runs like a 3yr old car. The only thing wrong with it is just the HG and my front right brake caliper (no sense replacing if I'm gonna junk the car). Don't have the skills, time, and equipment to timesert and fix the block myself.

    Anyone know any good mechanics willing do to timesert/norms my baby in NYC/LI area for a good price? Otherwise I'll keep using for local till I'm ready for a trade-in.

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

    94 pearl Concours. Wifes well maintained car started having heating problems 3 years ago at 90,000 miles and HG let go at 101,000. Bought wife MB and no more problems. Started into N engine this week to see if could salvage something from this mess. Have been driving GM cars for 40 years and Cads for 20 years. GM should be very ashamed, I have learned my lesson. One question I haven't seen answered is why is there no class action on this? Thanks for all the good info everyone.

    1999 Deville blew a headgasket about 350 miles from home after almost 1500 miles of a 1850 mile trip done. Drove it home at about 63 MPH and it did not overheat at that speed. Had it into the dealer the next day and three days later it's home again. extensive work done as well as the HG's and time serts. New hoses, heater hoses and bypass hose, new plugs and wires, new belts and maintenance on water pump belt idler, new oil pump (so much sludge in pan that the tech wouldn't trust the old one) new water pump lots of new gaskets and seals. And they did a four wheel alignment since the engine cradle had to be dropped to work on the engine. All this and it only had 92,626 miles on it. At first I was going to trade it ASAP, but decided to keep it now. After looking at how far I drove it in the condition it was in and it never failed, well, that's one really tough engine in my book.

    Richard, I was wondering where you got your Deville done at? My dealer had one the other day that had a similar problem to yours.

    I had the work done at Trent Cadillac/Olds, the same place I bought the car from, and the same place you work. Yes they are expensive, but so far they have been honest and I've never had to take a car back to have the same repair done twice. We have bought two cars from them, and are thinking of getting an Escalade for my wife. So you also live in New Bern? My Deville is pearl white. Could that have been what you noticed? Brian did the work, and other than a couple small details that he has since corrected, I am impressed with him.
