Oil in intake valve and air filter pan

Just to get some clarity. I'm guessing you mean the throttle body, simply because you say oil is on the air filter.

Are these the only places where there is oil? Is is all over the engine? and are you talking internally is my guess.

If you have a few pictures of what you are seeing that would be the best. I'm not sure how oil would get on the air filter if the jeep still runs. Others may have encountered this though.
