[93GTDIN]

So I was at seguin this friday, and I ran my car for the first time. First pass got decent traction, 2.1 60 ft and ran a 14.09 @ 98 with a passenger. Not bad for an automatic convertible. On the second pass, about at about foor 1000 of 1320, I hear this loud pop, and actually feel it through the pedal. I start smoking and the car isnt feeling right at all. That pass I ran a 14.09, the exact same time. I know its got a better pass in it because it stopped pulling after the pop. I pull to the parking lot and popped the hood. I had oil all over my upper intake, on the headers, and the drivers side valve cover. My first thought was that I blew a valve cover gasket, so we removed the upper intake to find oil spilling out of the runners. I even had oil in my throttle body. It still ran but it overheated and just plain didnt feel right. (especially since i broke a vacuum line putting the upper back on and i had no breaks and it couldn't idle) What happened to my car that second pass?
