[1987tc]

I have just finished getting an 88 Tbird running ( V6) and it has been sitting for probably close to a year. It runs and starts right up but I have a real big problem..... SMOKE lots of thick white smoke. Here is what I am wondering, Would reallllly old gasoline make it smoke white?
The gas does smell like turpintine. It seems to not run too bad ( I have not tried to take it on the road for obvious reasons). There is about 9 gallons of gas in it going by the dash ( digital). I am Hoping that the old gas is the problem. I bought the car with a leaking head gasket so I did not hear or see it run before I bought it. The car has been well cared for and there is no sludge or any trash in the oil or coolant. Any help would be great!

My second question is does anyone know of a good vacuum diagram for this car? It was partly apart when I bought it so I don't know how everything was hooked up.
Thanks!
