"Oily" smoke may have blue color with various hues - from transparent blue to blue-white, depending on the engine operating condition, and the degree of the oil heating that got into the cylinders. I have noted a bit of white smoke when this happens, and I have also noted that the car seems to use or leak water, although I can see NO TRACE of water in. The number is EASA AD 2005-0023 and the document can be found here After a short discussion with our LAE it seems that he will have to invest in tooling and we will have to invest in the inspection.
