there is oil EVERYWHERE!

[brian89]

Well as the story goes, driving down the road, going about 90-100mph making 32psi, as i started to slow down i smelled burning oil, look in my mirror and there is white smoke, i wasnt burning oil thru the motor it was just drripping on the hot motor and exhaust, when i looked under the hood there was oil on the hood, all over the motor, all on the under side of the motor, it was absolutely everywhere, and when i got a chance to try and see where it was coming from, it seems to be coming from somewhere on top of the motor near the back, dripping down the exhaust, any idea on what the hell it might be or what might have happened or how the hell i fix it is much appreciated, thanks

My buddy in his e99 had the same problem, it blew out the ICP sensor. Give that a check maybe? I saw the aftermath, it got oil everywhere.

High-pressure line or fitting failed?

[brian89]

What does icp stand for and where would i find it? And where would a high pressure line or fitting have failed? My best quess is somewhere on the turbo?

[phantom-3k]

icp, is injector control pressure. its in the high pressure oil system, what drives the injectors. I am not 100% sure on where it is on the 7.3s. hopefully someone will chime in on the location.

[brian89]

I looked up the location and it is saying its on the L-head? And its saying that it is toward the front of the motor, its leaking down the back like its coming from the turbo? And my oil pressure gauge is saying that im carrying good oil pressure? Im so confused at this, not much a diesel tech, so i have no clue

[phantom-3k]

same here, so hopefully someone else will chime in for yah

Try checking the High Pressure Oil seal located on the back side of the Oil Pump. This is on the top front of the 7.3 and is basically just a plug that requires an 18mm ratcheting combination wrench. I had this exact same issue about three years ago. All it is is an o-ring and the cost then was $9.00 from the the dealer.

[brian89]

If it was that would i be able to see oil running out of it while its running?

[Brutal01]

Yes. Make sure you refill the crankcase first though. You might be able to look back there and see if you can see part of the o-ring hanging out too, or feel it. When mine blew it blew part of the o-ring out. I did all of this after consulting with my local dealer and at their recommendation, tearing half my engine apart unnecessarily.
