Blue smoke on cold start.

[Dereksilbernagel]

So my pick up also spits ALLOT of blue smoke in the morning when i start it. It has an aftermarket Garrett turbo and the guy i bought it from said its smoked like that ever since the turbo was put on. I do need to replace the glow plugs and am wondering if that may be part of the problem or if im going to need new injectors. Right around 155k so im very worried. Thanks everyone!
