I have a 2001 7.3 F-0250 that seems to be blowing wet oil from the exhaust. I had 4 bikes on the car trailer going north and I found oil all over the right side bikes, especially the front one, and an oil pattern that seemed to spread out down the length of the trailer from the far right side, getting wider to the rear. The underside of the truck is dry, and it is not blowing smoke. This is wet oil that can be wiped with a finger. Lately under load it has been showing a "Service Engine Soon" light on the dash that goes away after a few miles under normal load. I am suspecting a turbo leaking oil under boost, as I was standing on it up the hills. Has anyone had a similar experience? Any advice on how hard it is to change a turbo, and what is a good repair? Cartridge kit? Rebuilt? Thanks.
I would suggest starting with a OBD2 dongle and the Forscan app to check codes and monitor some engine PID's. There's info in the tech section at the top of the page for recommendations on the correct dongles for our trucks and some walkthroughs for using the app.
I believe you are on the right track about the turbo, when mine went out it covered the right side of my horse trailer with oil. I did the bellowed up pipes & put a 38R turbo on mine when this happened. Changing the turbo isn't that bad of a job but I didn't want the fight with the up pipes so I had a buddy that owns a shop do the pipes & turbo.

OK, so I didn't see a "tech" section, I'm sure I'm not looking in the right place. I have no idea what a dongle is, or what I need to monitor an "app".
Is this something a parts place like Auto Zone could check from the OBDII port?
The oil sounds like turbo thrust allowing oil past the seal ring into the exhaust. Turbos are easily rebuildable but watch for wear on the compressor backing plate. We had to buy a new plate for dad’s truck due to the wear. It would have been easy to think it was “normal” and overlook.
Down the rabbit trail…. A Riffraff billet wheel and some cheap SS bellowed uppipes are good to do with the rebuild.

OK. Found the tech section, thanks!, I have a code scanner that plugs into the OBDII port, but of course it is 1000 miles away for the summer, and I do not know if it will work on a Powerstroke, or diesels in general.
It seems the turbo is the only place oil can feed into the exhaust and come out wet without becoming smoke, (if it went through the combustion chambers) and rebuild kits seem reasonable. I see some "wheels" advertised that promise better performance, are we talking just exhaust side turbine wheels? Or would we want to do compressor wheels as well? Ads I see really do not seem too specific as to which side we are talking about.
Spending a little cash to improve performance is not out of the question, but about 6000lbs is all I tow, and while I have a plug in programmer, the stock setting seems to have less smoke, and better mileage, so I don't use the performance settings, and it has either a no tow, or a 3K limit. Seems kinda pointless to me. However a better performing turbo seems good for any tune stock or otherwise. What are the advantages to the SS bellowed up pipes over stock for a stock engine? I do have a 4" straight pipe exhaust.
