2000 deville oil in the coolant reservoir and rough idle
Hello everone, I have a 2000 cadillac deville "base" that has a mere 130000 km on it. Last year on chrismas day I was driving to my girlfriends house, and the car started losing power and idleing extremely rough. I pulled into a parking lot and inspected the car after it cooled down. There was oil in the coolant reservoir, and when I turned it on it sounded like it was runing on 6 cylinders. It did not overheat and never had In the past. I heard the famous gargling sound a little a few weeks before this on a few occasions. I know that is a tell tale sign of needing to repair the cylinder head gaskets / bolts. Fast forward to last month. After sitting for almost a year. I plug the battery back in and start her up, she starts right away with the same old hesitation and lack of power. " I did not expect any better. Now i see smoke escaping from the front cylinder head area on the passenger side. My question is do you think it is a blown cylinder head gasket, or something more serious like cracked head or block. Thanks for your help guys/ gals im open to all opinions.

Well, its probably worse now. Who knows how much coolant mixed with the oil and caused other damage. More than likely its the typical Northstar head gasket issue which would require pulling the heads.

Brendan If it is leaking/smoking by the cylinder head it is most likely the gasket.
This is probably something best left for professionals to deal with.
I am not sure where you live, but an engine rebuilding shop could have a better look at it and give you an idea on cost to repair.
