Recently put new fuel filter and air filter because of rough idle and smoking a lot. Had troubles starting, hard to crank. When idles its rough and white smoke pours out the tailpipe. Any ideas what's going on. Buddy of mine thinking head gasket or maybe injectors. Heard of issues with both.

What color is the oil? Are you losing fluids after the motor is run awhile? Is the smoke actually smoke (blueish tint) or is it white like steam ?

Oil is black. Coolant was a little low, did not notice usage while running, did not want to run it very long. The smoke is actually white to me. Do I get a notice on email that there is a response to the question or how does it work?
