Hey guys, im new here, and to the diesel world, just got myself a 2002 f250 7.3l PSD (184k) not to long ago and im loving it. Coming from the jeep world im really liking this truck, and it sure seems alot more reliable than the 4.0 in my TJ. ?
Heres the issue im having right now though. Since the weather has been cold its been blowing blue smoke at start up. But ONLY at start up in the MORNING when it hasnt been running for more than, say, 8 hours. Theres no white or black smoke. It smokes for about 5-15 seconds and smells like burnt oil, no sweet smell or heavy diesel smell. During that time it idles a little rough like its burning the oil off, then its as smooth as ever. Plugging it in overnight doesnt make a difference, and glow plugs are fine cause it starts up right away no hesitation at 40 degrees w/o being plugged in. Just blue smoke for a few seconds. AND threre's no noticeable oil loss from the dipstick.
So far i have replaced:
Changed oil to 5w-40 rotella T synthetic w/ a napa gold oil filter
Fixed a HPOP leak and fuel bowl leak from bad orings (not really relevant)
The only thing i can think of is Valve seals or Injector orings, and judging by the fact that i have yet to read of anyone with bad valve seals on the 7.3 i think its the injector orings.
Am i on the right track or am i missing something?
