$30k restoration? Nope...never. You can buy a new/rebuilt one for less. Blowing oil out of the tailpipe usually means o-ring failure in the turbo pedestal, but there are other failures. Possibly injector o-rings with the vibration, but there is much diagnostic work to do first. Have you run the KOEO and KOER tests that Forscan can do?

If it were here, I would use a manometer oil the oil fill to check crankcase pressure. It should be less than 4 inches of water column. You could just flip your oil fill cap over. If it blows upward pretty good, yes, you have excessive blow-by. As to vibration, you said he was drunk. He might have gone full on yahoo, took it off road and did something to the driveline.
You need to isolate engine from driveline. Get it up to normal operating temp and take it slowly all of the way up through the RPM range in Park to see if you have vibration. If you do, excessive oil during the drive may have camebup through the breather, took the trip through turbo, intercooler, and into engine. If it got a good enough dose, a rod or two may have bent a bit. That would shorten the stroke a bit. This might be detected through cylinder comparison or measuring down to the piston through the glow plug hole.
Rods aren’t the end of the world. I don’t see ring blow-by being caused by an overfill.
Muffler may have a ton of oil pooled up in it and will smoke forever until it gets drained or burned of. This will cause an exhaust restriction which will effect performance in RPMs above about 1500 RPMs depending on how much is in there and they can hold an awful lot.

First question is there a personal attachment to this truck? If so I don't it will cost 30 grand to replace the motor. Dude never let your friend change your oil. You may as well go to the dealer. They dont drink and do oil changes. I am not sure 3 or 4 quarts over will do much to damage the motor. It mostly has to do with the crank counter balancers hitting the oil in the pan. As for blow by many things could cause that. I would look at the PVC system and make sure that is is working. You could do a compression test to make sure your pistons are keeping the compression in the cylinder and not letting it go by the rings. If you have compression loss in one or more cylinders will cause vibration. I would just start with those suggestions first. 30 K for a new motor is a joke even if the dealer did it.
