Veg-covered!? How to clean off?

[Ruan]

You wouldn't be able to tell from the smoke output, it's the glycerin that's exiting the cylinders unburnt... unburnt glycerin doesn't make smoke, well, just a very light haze but you wouldn't even notice it... Over 1200 miles, it wouldn't take barely a haze to cause that...

There's definitely something not right, your cylinder temperatures are not getting high enough to burn all of the fuel, hence it's ending up on the back of your car...
