Engine Knocking and Smoking!
I have a '91 5.0 that is stock and I am trying to figure out what is wrong with my engine. It has started to knock real bad when I accelerate and when it does I get alot of smoke out of my exhaust. I know the oil is not low because I just changed it this weekend. I was at an auto hobby shop and had my timing checked and it was adjusted back down because it was high but it wasn't able to be adjusted back to stock settings. I am just trying to pinpoint and issue but am not really sure where to start. Any suggestions?
