88 XJ Blowing Oil

We have a 88 Cherokee XJ with a 4.0L with 140k miles and the line coming off the top of the valve cover and going to the air box has oil in it and it's making a mess of the air box. How can i stop/fix this?
Thanks

Re: 88 XJ Blowing Oil

It also helps to just make sure that the other line going from the intake manifold to the valve cover is clear. If this blocks up, the blowby can only go down the other line to the air cleaner. The line from the air cleaner is supposed to supply fresh air to the valve cover as the intake manifold draws that air through.
