test drove a 08' 6.4 and i drove it town a few miles and it was great, I got on the on ramp for the highway and started to put my foot into it and for about 100 yards blue smoke was coming out the tail pipe, After that it was fine for the rest of the test drive... i really like the truck but that kinda scares me, any ideas? FYI its all stock with dpf and 86k miles
