Hey guys, firstly thanks for the responses so far. It does send a small amount of dark grey smoke out when laboured at low revs. I've checked for the symptoms of hg failure, the cooling system isn't pressurising any more than it was before, I can't see any signs of water in the oil or oil in the water.
@londondan. The smoke doesn't dissipate like steam, it lingers in the road and slowly disappears. I thought maybe water in the fuel or incorrect timing but surely that would be all the time not just when the engines cool?
