Afternoon all,
I have a 65000 mile 2010 diesel which has an issue I've been chasing for a while.
Currently under a good acceleration there are large clouds of smoke, white ISH maybe blue. Then even on tickover it just smokes.
Started out with the ever common dpf blockage issues which I have seen are well documented. Cleaned the dpf, issues returned in a couple of days. Pressure difference was to high, soot climbing to much, engine light on etc. Spoke to a mapper and he mapped out the DPf and egr, and I put a 2 inch hole through the dpf core. No more issues with the difference pressure now! On a side note, passed MOT emissions fine!
Then I started getting a lot of smoke out of the exhaust, so I'm guessing the original problem is starting to show itself, a lot of oil in the inlet, so replaced turbo, car feels much better. Smoke went away for a short while, but has since returned.
I've smoke tested various pipes, no leaks found.
With the engine running, I have some positive crankcase pressure, but doesn't seem excessive, but would like to know more about this if possible, I can't see a pcv anywhere to check. Do they exist?
What ever it is, it feels like it's blowing oil through the turbo seals and out of the exhaust.
Any other ideas would be a great help as it's starting to test me!
Kind regards
Martin
