Frustrated with car dealership

[WhitecatD]

So I took my 2007 Cobalt into the dealership because it was making some pretty substantial valve-train noise when you would start it. They kept it kept it for two days trying to figure out the problem and decided to replace the entire cylinder head. So I have to wait an entire week for parts to come in and they didn’t provide me with a rental! They said that they could not give me a rental until all the parts came in. This makes me mad because I drive fifty miles a day and now I have to drive our one-ton truck to work. So they replace the cylinder head and I go to pick it up this morning. Everything seemed fine and I drove it a couple of miles to work. When I got to work I smelled antifreeze so I popped the hood and found oil and antifreeze all over the engine. Ok, so they didn’t wash it off or make any attempt to clean it up. Then when I get off work I come out to start the car a whole bunch of white smoke starts pouring out the exhaust and the car is running rough.

Head gasket? But it's not over heating... They suggested antifreeze in the exhaust system and some got on the O2 sensor but again for this to happen it would have had to been careless disassembly/assembly. But where is all the smoke coming from? Did they pour a gallon of antifreeze down the exhaust system and into the cat?! Who knows I just want my daily driver back!

Now I have to take the car back to the dealership for a third time to have it fixed again! It seems like I am spending every morning at the dealership either dropping off my car or picking it up. What a pain in the a$$!! This is all under warranty the car only has 35,000 on it but still what a pain!
