Smoking while idling
I've been very happy running stage 2 for the last 20K and no real problems have arose. A few months ago there was bluish oil smoke coming out of the exhaust only when idling and the problem went away after a week or so before I could even change the oil. The problem is back now and it also smokes under light acceleration too. I'm running XPT stage 2 map @ 16.9 PSI, TBE and K&N and no other engine mods. Stock T04 with 90K. Rotella T 5W40 with only 3K. What oil would you guys suggest? Could my oil have lost it's viscosity? Could this just be a gummed up valve? I've got a used TD04 that needs to be overhauled and seriously thinking about doing it soon.
