I bought the engine from a guy with about 10,000 miles on a rebuild. Mild build with all the paperwork from the machine shop. It had been sitting in his garage for a few months. He pulled the engine before selling the truck it was in. I installed it in my nova. New oil, edelbrock intake, carb ... I have it all hooked up ready to go. Upon starting it I had a little white smoke coming from the exhaust. Once I took it down the road it started smoking the alot out of the drivers exhust pipe. The smoke smells like coolant. I drove it on the highway for about 10 miles and the smoke stopped. Once I got off the highway back to the house and sat at the red light the smoke came back and smoked out the car behind me. I got it home still smoking. I am hoping it is just the intake gasket leaking and not the head. I still have the guys number if he screwed me on the engine. Is there anyway I can tell? I plan on taking the intake off today if the rain gives me a break.
