Well if the exhaust smells like coolant sweet smell and its puffing smoke out like a locomotive it doesn't sound good maybe a cracked head or head gasket, I'd do a radiator pressure test and leave it for a couple of hours to see if it lost pressure...

The heads don't crack on these things. A cylinder liner, maybe (#7 ?) - there have been a couple of those in here over the years. Sweet smell and heavy vapor is coolant.

Not good, Kemo Sabay.

If it is steaming that badly, your coolant level must be dropping as well. I agree with the Lone Ranger........ not good.

Dude... If those two ^^ say it's the headgasket... it's the headgasket. Do yourself a huge favor and don't spend too much time looking for what-if scenarios. Have the block test done and you'll have your answer.

It is not cold enough ANYWHERE in the country right now to warrant THAT much steam.

It is very odd indeed for a head gasket to go like that. They generally start very slow and work there way up over a very long time. I've never heard of one going like this. I just can't think of anything else that would allow it to be ingested.

The intake is dry. There is no coolant running through it.

yes indeed a head gasket...after many good devilles i have had this is the the first to crap out like this...engine is way to expensive and to service the heads on this one is no fun. as nice as it is to have one im gonna get this one ready for auction and make sure i sell it one way ticket.im gonna try blue devil stuff or motor purr metallic seal up i used motor purr on other cars and it seemed to help. its temporary but the only solution i can think of.at this piont which i know you are all against is any other stuff i can use to temporary fix??????? thank you caddy forum

We always tell people to check the free things first and verify BEFORE spending any money. That is documented and pretty easily proven. The only money I ever tell anyone to spend is on a test kit. There are enough people here that know the truth and can see through your lies.

Can you tell me the specifics of the car you sold at auction? I am curious about how much you got for you car at auction? As I am trying to plan out what I am going to do with my 2003 Deville DTS 110K (w/navigation/nightvision/all other options). You can see my rant thread here. http://www.cadillacforums.com/forums/cadillac-deville-1985-2005-including-1985/172616-2003-b0249-door-blend-problem-blower.html
