Update, so after my injector change with oem s, (and cleaning the carbon with home methods some egr cleaner brushes etc) the smoke has dissapear, it doesnt make when its stationary or when i ride normal, when i throttle it there is a litle bit amount of smoke there i find normal, (i have downpipe wuthout cat and rear muffler delete, i have just resonator at all my echaust system). Now smells like burned petrol some mechanics said that car run too rich. (and they said mybe its due to a chip tuning mybe they didnt stage it correctly) The only time when smoke now is when i ride downhill on gear without gas and when i stop at red light, and begin to ride make a big cloud behind and then nothing. I checked the rear pcv valve, has a litle bit oil inside, and i found a litle amount of oil inside turbo too, i cleaned rear pcv, and turbo too, i also checked the valve cover for cracks, i repaired the crack too with some gasket silicone hope still is in place. But after all that, smoke on downhill continue. The compression is good no oil consumption or coolant consumption. Front pcv just removed to see if there will change something. Any other suggestions? Thank you.
