Truck randomly started black smoking
 

Hey im new to the site but need some help,About a month ago my truck started to make a injector knock then quit , now it has a really light knock and started black smoking like a freight train even on light acceleration, and the smoke smells like a sulfur ish gun powder type smell and its never smoked till a few days ago and its running hotter than usual.. I've checked all fluids and they look good,plus I've cleaned the air filter and changed fuel filter about 5k ago can someone plz tell me what's wrong with it ?

Any ideas what's causing this ???

I'd check your inter cooler boots if you have a leak it will run higher egts and smoke
