think its the heater plugs, got to pick new ones up to moz and try and fit them, wouldnt start and took heater plugs out and they where covered in oil, it is either the turbo has a problem and is leaking oil or it was diesel mixed with soot which made it look like oil, but its been that cold, cant be bothered standing out side, want to get a new van, as heating packed up 2 weeks ago, but am all skint for xmas now lol,
