Ok, i did the ccv mod a lil while ago and i noticed a puddle of oil in the intake tube right before the turbo. acually a majority of it was in the piece that got replaced by the 4" pipe. anyways my truck smokes a decent amount no matter what temperature, in the mornings or during the day. buy only when it hasnt been run for about 8 hrs or so. and goes away once warm. all this oil (vapor) as i understand is being sucked into the turbo through the intercooler and back into the motor. the truck doesnt use hardly any oil at all between changes and it only has 46000 miles on it. so all this smoke as i guess is the oil from the ccv being cycled through and burnt and my smoke problems should go away once this gets burned out, probably in the next 10 years. but anyways just wanted to throw that out for comment. thanks!
