White Smoke

No there hasn’t been another Papal election. Our van seems to have far too much white smoke coming from the exhaust. I’m not a mechanic, but from what I can find on the internet it could be several things. I’m hoping it needs a few glow plugs replacing. Not sure what we’ll do it is something more major. Gasket gone, pistons knackered, generally needing an engine rebuild, are all expense possibilities.
