I know I’ve talked about this,,,,but maybe someone hasn’t seen it yet,,,,besides this was my fun for the day,,,,N20 smoke during cold start up in the morning,,,,it’s a blue smoke,,,smells like burnt oil,,,,it will smoke for about 20 to 30 seconds and then go away,,,,the picture is the engine oil feed line to the turbo that causes the problem. Here you can see the turbo,,,,and just left of the turbo is the engine oil feed line,,,,the oil line goes from the engine block to the turbo housing,,,,you have to remove the whole turbo to replace that oil feed line. Here is the difference between the old and new oil feed line,,,,the new oil feed line has a built in check valve,,,,which stops oil from leaking into the turbo while the engine is off,,,,what would happen is oil would leak into the turbo over night and cause the blue smoke coming out of the exhaust during cold start morning,,,,that check valve in the oil line stops that.
