That would be great if it was, however, I was monitoring exhaust temperatures when I took it on the motorway and I did see excess temperatures of 500 degrees Celsius or so. On that 35 mile run I came back with no smoke, I was really happy and assumed its all sorted. Then I did a small trip and it was smoking yet again, that's when I thought maybe the diesel fuel builds up in the valve cover and then spills over to the exhaust but then I fixed the faulty fuel return line and yet it's still managing to smoke.
I can't help but feel if this in in fact residual oil/fuel it shouldn't have been able to do a motorway run with DPF regen exhaust temps and not smoke, but then smoke like this from a small dual carriageway run.
I'll take it out later and see how things go.
