Why is there oil in my air filter box?
XJ's commonly, over time, build up gunk in the PCV and CCV valves/lines and create pressure which then pushes oil into the air filter. Replace these valves and lines (parts from the dealer) and the problem SHOULD go away. If it doesn't, you may need to clean the inside of the valve cover.
Hope this helps.

 Thanks for that.
Just for info its a '96 ZJ, but sure the same applies. I also get a hydraulic tapping when starting the engine which stops once the engine is up to temperature.
