Dealing with a runaway engine?

    Leaving Galway today I came across a Merc pulled into the side spewing blue smoke at an extraordinary rate - it covered the motorway like fog. It seemed that the driver could not stop it.
    Now I drive a Volvo with a D5 engine and Volvo warns against over-filling the sump with engine oil. In fact there is a sticker in the engine bay stating that it should not be filled up to the max mark on the dipstick - but to a quarter inch below that mark. The reason I am told is that engine oil can be sucked into the cylinders and ignited just like diesel and this causes the engine to run on uncontrollably.
    My question is, does anyone know how to deal with this problem if it occurs. How does one stop a runaway diesel engine burning its own lubricating oil?

    This happens to only happen when the turbo blows catastrophically. If you are sharp you can stop it by going in to 5th gear foot on the brake and stall it but if it has steam built up the only way is to fully smother the intake, which is not easily don't quickly and with no tools. I find a co2 fire extinguisher works well sprayed down the intake to stop it sharpish

    This ^^^ If you have an auto you won't be able to stall it so take a few minutes to find out where the air intake is and carry a co2 extinguisher. If the air intake is to difficult to access strap a sharp serrated knife to the extinguisher which will allow you to cut through the flexible hose running from the air box and horse in the co2.
