Its most likely coming out of pipe fuel injection burns alot hotter and more efficient than carburetion,you wont see as easily unless someone is behind you on road! Most likely its coming from valve stem seals-sucking into combustion chamber,more ideas worn rings,plugged pcv valve(check valve for free operation-easy cheap fix can consume oil),you can perform compression test to see if could be rings-(valve stem seals wont show on test if rig has over 100,000 miles they get brittle and crack allowing oil to **** into combustion chamber(they very inexpensive but labor intensive to change, i always buy best one money can buy),anyhow hear is some ideas i hope that they help!!! :)

Hello;Are there any service lights on in dash?It could be that the fuel pressure valve went bad,causing it to get to much fuel, and thats were the black smoke is coming from.

Try running fuel injector cleaner through the gas tank. A fuel injector might be stuck open, letting lots of fuel into the engine. Also try replacing your fuel pressure regulator, and inspect the fuel tank return lines.
Good luck
