What the crap is going on?

I was rushing to get to school on time after work, because I only have about 10 minutes to get ready between the two, and I put a quart of oil in my car. I have a jacked head gasket and it pukes oil. I didn't check the dipstick for lack of time and a paper towel so I blindly threw a quart of oil in. My car loses oil pretty rapidly so I figured that 1 quart would sufice. When I was on my way to school I was talking to my fiancee, who was following behind me, on the phone. All of a sudden she says "Pull over, your car is going to explode!" so I looked back and I couldn't even see her car, due to a huge cloud of black smoke boiling out of my tail pipe. As I drove for about 1/8th of a mile farther the smoke died down, but was still presently coming out of my exhaust. I stopped and shut my car off, locked it up and left it on the side of the road. I checked the oil, but I couln't really get an accurate reading.

What do you think the prob. is? Did I put too much oil into my engine?

Your head gasket just blew up:devil:

It was the coolant burning in the engine that made that huge pillow of smoke. Same thing happened to me a couple months back. It prolly will start back up but if you want to keep that engine dont drive it.
