How many miles on them?
The oil I was talking about on the exhaust of the turbo and if you zoom in on the motor pic you can see all it covering the inside of the downpipe. What could’ve caused this? Turbo spins freely.

The bearings can leak oil and still spin freely.

So the turbo needs rebuilt. But what could cause it so abruptly? It’s never leaked oil through the exhaust before until that night. And it never seemed like I was having turbo issues before that day I was going to have it towed home.

They can just fail. That said, high temperatures can cause early failure and so can fuel dilution of the oil from bad injectors.

I've always been told, if it's your turbo seals leaking, your Y pipe connection should still be dry. Yours isn't, which means that the liquid is probably coming from further upstream (hint - you just resealed your injectors and you said the smoke smells like raw fuel). I think what you might be seeing as "oil" is actually fuel mixed with soot from the exhaust. That being said, you may also have a bad turbo seal as well, but you need to figure out what's causing the issue upstream of that before you'll know.

Does your smoke look like this:

Blowing raw fuel to the extent it sounds like you are experiencing can cause some major engine damage. You may want to invest in a borescope.

Since you are sure it is oil out the exhaust, it sounds like the turbo is shot along with injector problems and possibly injector related engine damage.

Got the heads off. Pistons look good. Cross hatching looks great. No abnormal wear. Heads look good as well. I’ll snap some pics tomorrow and get your guys opinion.
