So am I to understand there is a replacement paper filter element on the right front of the engine? This engine does not have anything like that. Does / can it just pull through the main engine air filter? Does it have 2 pcv valves, one on each side?

Is this the pcv valve? Middle of valve train, under the cover?

In this picture the PCV valve is right next to the spark plug wire holder under the valve cover. Looks like a little pipe fitting with a hex head and a small hole in the top. If a GMC V-6 does not have a breather hose going to the air cleaner from a cap on a valve cover or the back of the block, there is a small separate breather air filter in a small can behind the left (driver's side) head. Looks like you have a cap with a hose, so there would not be a separate breater air filter.

You should have a vented gas cap. When your truck stalls quickly pull the gas cap off and see if a vacuum is building up in your tank.
