What would cause light brown creamy foam to cover the inside of my oil cap and valve cover opening? The truck seems to be jumpy or missing timeing.

When you said creamy light brown foam on the oil filler cap that lead me to think blew headgasket or cracked head, and when you say a miss or jump that just about confirms it.
