Oil leak at turbo and inside ait 2 air

We just all of the sudden have a leak. Not a drip, it is running on the ground. Originally it seemed to be coming from the rear main seal, but upon closer inspection, it has filled the valley on top of the engine and there is oil in the air to air unit, too. Could this be a turbo? Could it be the pedestal or a line? We have 4 Powerstrokes and this is the first one to do this. Any help is appreciated!

not sure what air to air is, but sounds like the non-servicable plug gave way, or the fittings on the hpop, and/or the hpop lines. Try cleaning it up good, then fire motor and take a gander. Hopefully, it aint a line "waiting" to pop

Sounds like turbo leaking oil. Could be high pressure oil line..

How much oil in air to air. You should have some from the crank case vent on driver side valve cover going into air intake.

Not a whole lot in the air to air, could be from the vent. Looks to be coming from the turbo. Pulling it off tomorrow. Thanks!

Another thing that made me question the turbo is it wasn't smoking. I don't know about a Powerstroke, but when a Mack blew a turbo, it lost power and smoked like crazy! Is this motor different? Thanks again!

UPDATE- The dude working on it tells me this morning that now it's leaking around the HPOP. It still runs so I don't think it's the HPOP- maybe a line from it? Help! This guy is killing me!

orings under the line connectors bud, BUT you need to use loctite as well. The oring by itself will not stop the leak, plus it could also be leaking from the non-serviceable plug....
