Taking the car back to Wales tomorrow to re-unite her with her old owner for the day. Ran the usual pre-trip checks today and I noticed she is puffing out bit of black sooty smoke out the exhaust. Anything I should be overly worried about or is it just cos she's a bit choked up with me just running her up in the garage. No signs of oil leaks and it's definately sooty as opposed to the sort of bluey hazy smoke I would associate with her burning oil.

Any advice appreciated.
