Let's see , countless hours developing a low loss, optimal swirl induction system and then spray it with a carbon oil sludge. To reduce it try keeping the EGR mixing chamber clean , maybe it will act as a trap. Is the crankcase breather system working properly ie draining freely and not sending oil to the turbo inlet. Nobody seems to have opened one yet. Still think there should be a drain on the intercooler. Is there a small leak in the induction system allowing more smoke than normal. Could other choices of fuel and oil reduce smoke production.
