blue smoke?

[Leisurlee]

2001 F 350 manual 122,000 miles. Understanding that these vehicles will smoke at startup I have no issue at that time. However I do not understand why it smokes after I set at a light or stop sign, doesn’t matter if I sent for 10 seconds or 1 minute. It will smoke blue until the turbo spools up then turns black, what’s the deal?

Could be a seal in the turbo going bad and leaking oil, or could be lower injector o-rings allowing the high pressure oil rail to leak into the fuel rail.

pull the intake tube off the turbo and see if the shaft has play.

Had the valve covers off about a month ago and found the intake duct was cracked, at that thime I checked the wheel on the turbo, no noticable play at that time.

that would mean the bearing isn't completely gone - but the seal could still be leaking.

Is the seal something I can replace? And are there any threads in here talking someone thru the injector o-ring replacement?
