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.
