blue smoke
Engine's faint plume
Blue smoke is the visible exhaust from an engine burning oil rather than just fuel—a sign of worn seals, rings, or other internal problems: The old truck left a trail of blue smoke.
In computing and electronics, blue smoke refers humorously to the irreversible failure of a component, from the joke that electronic devices run on "magic smoke" and stop working once it escapes: I plugged it in wrong and let the blue smoke out.
