I have recently run in to trouble with my Vauxhall Corsa 1.2 2013. I broke down the other day after a huge cloud of white smoke out the exhaust followed by a severe loss of power. The AA came had a look and said that the smoke I saw was the oil burning out, this must have been all of it as I topped it up 2-3 weeks prior. They towed me to a garage and they tried replacing the ignition coil and the spark plugs as they believed this to be the solution, it wasn't as the car still had no power and went through the oil again. The mechanics said they didn't know what could be causing it and suggested a new engine to be the solution.
So my question is has anyone come across this sort of issue before and/or does anyone know what the issue/resolution would be?
