Engine Mechanical problem
1987 GMC C2500 V8 Two Wheel Drive Automatic
I purchased this truck and did not notice smoking going on. It doesn't smoke all the time. When driving at hiway speeds, and to deaccellerate, a puff of smoke comes out. It also smokes at dfferent times. If it's rings, what is the path I need to take? All other cylinders are burning nicely and the truck runs good now that I replaceed the plugs and wires, rotor and cap.
