I have a 1996 with dual exhaust beginning with dual headers at the engine. The exhaust pipe that runs to the header on the driver side of the truck is issuing a white smoke. Not real thick, and it does dissapate fairly quickly. However, it's just the one pipe doing it. I seem to lose a little engine power here and there but nothing major. Oil has been changed, I had an external coolant leak but fixed it and fluid level seems to be holding now. Ideas?

Due to the external coolant leak, you may have overheated the engine and you have a blown head gasket on the left side, take the spark plug wires off one by one and find out which cylinder is dead, due to your loss of power.
