1994 Oldsmobile 88 Royale
Engine runs good, most of the time, but occasionally when under acceleration from a standing or moving position the vehicle will bog down & blue smoke will come from the exhaust pipe. Except for these moments the engine runs fine. Does anyone have a possible explanation for my problem. I know that it is not a cracked head or gasket issue. I'm leaning toward crank ventilation issue but don't know how many possibilities there are. If anyone has an idea.
