Help:Bad smoking and oil on the exhaust
I've been noticing that my brakes had a little shake between 30 and 40 mph when I slow down easily. I figured my rotors may be a little warped or it was time to just get some new pads but before I did I wanted to do some really hard stops to see if it would help.
So last night I drove on a dark deserted road would slowly climb to 60 mph and then cram on the brakes with two feet. I did this three times no tire squeal just slowed down aggressively
On the third time I noticed as I looked in the mirror there was a ton of smoke coming out of the back of the car again no tire squeal
Then I realize the smoke didn't stop as I was driving and I thought maybe my brakes are locked up in the rear but I didn't hear or feel anything odd. And then I could smell an oil smell.
I pulled over into a local gas station and noticed that there was smoke coming out of the driver side exhaust pipes. And if I gave it some throttle the smoke increased pretty badly. I use my finger to wipe the inner part of the exhaust tips and notice that there was an oil residue inside. But only carbon build up on the passenger side
Here is a video after I let it sit overnight and turned it on this morning

Could definitely be pcv. Did any codes come up? Is the fuel trims abnormal? I would start by pulling the plugs and seeing what they look like. If you have one with oil then you know it's something one cylinder related like a valve seal,head gasket,etc.

Fuel trims ?
No CEL
No rough idle
I'm hoping it's just the PCV 🙏🙏

His advice is sound, also to answer your other question, no I would not drive the car until you can properly diagnose where/what the issue is.
The amount of smoke coming out is extensive enough that you have a consistent issue that isn't something you can "drive around" and not potentially either cause more or even extensive damage in places that are not affected yet.
This may sound odd but is there anything you smell that you can identify?
Normally oil is a bluer tint but you can also sort of smell it as well...

Codes will not always present themselves in these situations.

If you're not able to really work on the car for whatever reason I'd just get it towed to an MB dealer and pay their $200-300 dollar service diagnostics charge to figure out whats wrong and then you can have them fix it or do it yourself.
Otherwise, start checking your plugs as suggested above and don't drive the car.

I had smoking on decel. Sometimes it was a BIG puff/cloud like I did a burnout. It turned out to be my valve stem seals. They noticed when my heads were off getting cleaned and decked during my headbolt job.

I'd start by replacing the injectors, plugs and pcv valve. At 57K you're approaching the service for those items.

If it gets to a point were something major has to be worked on, take it to them.

Update
Pulled first plug. How does this look to you
At first I thought the stuff on the threads was oil but then I realized it's probably anti-seize

there shouldn't be antiseize on the threads anyway, at least from the factory. It's incorrect to install aluminum on aluminum with antiseize because the wet torque is different than the dry torque, wet torque stretches the fastener more to achieve the same fastener friction. It's probably oil.
It's not oily though. It's thick and sticky on nature. Any other suggestions?
