Oil in my air filter!!?
There is oil in my air filter. I was told it could be a bad pcv system. I havnt tried that yet but is there any other thing that it could be?
It's the crank sensor!
Jeep 4.0 has a CCV system, not a PCV system. You are probably experiencing some BLOWBY, a relatively common problem, especially on your vintage XJ. I had it on my 88 Comanche but it is really pretty easy to manage and it doesn't necessarily mean your engine is on its last leg. Use the SEARCH function for information on BLOWBY; no need to reinvent the wheel here. Good Luck!

Without "data", all you have is an opinion!
Check out this article. I have an 88 that does the same thing. I just ordered these parts a few days ago which will hopefully fix the problem.
