Excessive blue smoke on cold Start
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.
