Excessive blue smoke on cold Start

[hh1082]

My 2000 F250 325,000km is starting to miss, smoke blue and stink of raw fuel on cold starts, but it start right away even when it's down to -30 DegC and not plugged in. It runs great when it's warm, no blue smoke, and doesn't use any oil. I checked all the glow plugs, wiring harness, valve cover gasket wiring, and replaced a weak Glow Plug Relay with a 200A Stancor Unit. I think it may be time to replace the injectors, does this seem like reasonable assumption?

If I order injectors should I go with the stage 1 injectors or do I need to modify my high pressure pump. My truck has S&B intake, 4" MBRP turbo back exhaust, TS 6 position chip, and a wicked wheel.

Hoping to figure out this smoking issue, because my neighbours are going to start complaining soon. Also like to know if I'm on the right track before I drop $2K on injectors.

Sounds like the injector o rings may be junk. You could go with stage 1 but you will need a programmer due to the stage 1 being single shot And not split shot.

Thanks for the suggestion, I'll check the o-rings. Also I've finished the install of my Espar heater a couple of weeks ago. So now I start it up once the heater has the engine above 120 DegF. Needless to say, no more smoke on start up.

The Espar heater works great.
