F250 7.3L start up problems & burning tons of oil?

Asked by Feb 13, 2015 at 03:06 PM about the 2002 Ford F-250 Super Duty XLT 4WD Extended Cab LB

Question type: Maintenance & Repair

My 7.3 recently had some work done
on it. I replaced my O rings on the
fuel bowl cause there was a leak.
Then had to bleed the injectors
cause they had air in them. It's been
pretty cold out, so I plugged it in
overnight and all day. Had a little
trouble starting it up today, but got it
started let it warm up and took it for
a drive. It kept stalling out as I was
driving it. Took it back home and
parked it, shut it off and went to start
it back up. It starts, but sounds like
it's pulsating. As its pulsating it's
blowing a mixture of white and black
smoke. So I continued to let it warm
up and the whole truck shook and
the pulsating got louder. It eventually
cunked out and the check engine
light came on then went off. Started
it up again and it wouldn't start.
Hooked my f150 up to it cause I
thought I drained the battery. Still
wouldn't start. I checked the oil.. It
had barely any oil in it and I just put a
gallon in the day before. There's no
oil leak, so I'm burning tons of oil
and idk how. Please help!

check your exh.manifolds were they bolt to the head see if any are wet around sides,cranck engiine and feel them with your hand if 1 is cold and the other 3 are warming up your gonna have to pull the injector and check the orings for cuts they are oil controlled by the icp thats the easiest way.if you really want to pin point pull the exh.manifolds all the way off and you will know exactly were the problem lies
