Car leaking oil,smoking from exhaust oil Sep Fix!

[8nutz8]

Experienced an issue in the last few miles of my drive to work this morning.
it was 4 degrees this morning so i let the car warm up for 5 minutes and headed out. ran normally for most of the way but towards the end of the drive i could feel a slight stumble. i had the heater on and there was a VERY strong odor coming through. smelt like something burning but can't put my finger on exactly what.
parked the car and left it running and looked around the engine bay. car was smoking from the rear bank and there was oil around the back valve cover. oil pooled out of the rear BOV.(see pic).
let it sit for a few hours. went out and checked oil level, it was almost a quart low. started it again without any trouble then it began smoking out of the tail pipes pretty heavy. engine bay was still smoking and car was chugging a bit and idle bouncing.
i could also hear a burping/slurping sound coming from what sounded like the air box. pulled the cover and it was dry. coolant level normal.
no dtc
no misfires registered

what could it be?
blown rear turbo passing oil by the looks of the rear BOV?
popped cylinder?-prob not or i'd have misfires.

i'm all ears guys!
thanks

Don't Drive it for the time being IMO!  Check the OCC lines to make sure there not frozen! 
Check the PCV system Oil Sep! Check the Oil Cap ? Hopefully it doesn't look like pudding!  Check for Codes!  Z

yep i'm going to check the occ lines on my lunch. i guess a check valve could have failed too.
would any of that cause this though?
no i didn't look at the oil cap yet. ill do that too.
thanks for the suggestions

no codes present as of now.

I'm hoping its not the rear Turbo! especially the Oil Cap pudding of death!
It could be oil inside the crankcase!  Check the above mentioned!
I'm hoping you have Warranty!  Best of luck.  Z

Right off the bat, sounds to me like a bad oil separator.  They do go bad in these cars.  I'd pull it and see if there's excessive oil in there. 

If there is, I'd replace that and the PCV valve and go from there.

Def pull the hose off the rear turbo, a must in a situation like this.  Ford has already acknowledged the valve cover / pcv separator issue, fingers crossed it is just that ...

pmezo may have hit it on the head. this is what I found. milky moisture at the separator. Oil cap and dipstick were totally clean.OCC lines seem clear and absolutely nothing came out of the catch can when I tried to drain it.

The only other thing I'm wondering is if a bad check valve at the OCC would cause this?

That's moisture mixing with the oil.  Looks like you've isolated where the issue is assuming the rest of your oil doesn't look like that milky mess because then you'll have much bigger issues.

Change the oil separator and PCV, clean everything up, and you should (hopefully) be good to go.

This is oddly similar to my oil smoking but mine was not to this extent. I think you can actually take apart the oil separator but the oring might go bad once you do. Wonder if it is actual oil sludge in the baffle. My OCC has been filling up with water in these low temps.

Looks like the oil separator is gone after 2014 SHO models.

I changed my oil separator and PCV... oil/smoke issues went away.

did you have to replace your oil separator or was it a different issue?

I was having smoke on decel after being on the throttle.

Changed the PCV valve and separator... added UPR catch can. No more smoke.

just read through your other thread. thanks for updating. so you just replaced the oil separator and not the valve cover correct?

i pulled off the separator and it looked far worse than yours did. all sorts of milky crud in there and  the pcv valve. ill get pics of it later. picking up a separator from the dealership now

new separator on and problem solved! thanks to all who commented to help the diagnosis. once again the fine folks here have proved more than helpful.

here's the old separator. . nasty.
blew oil all over the rear of the engine bay
just got done cleaning stuff up and spraying down the map sensors. ill be doing a more thorough job on my upcoming weekend.

Interesting...Seems like the OEM separator works really well until full....I've always wondered why people install catch cans on these since they are basically equipped with one.

Seems like this should be a maintenance item.

Wonder if the 2.0 ecoboost has one?
