Oil in air filter? (1992 2.5L YJ)

I have found a mixture of oil/gas in the airfilter and was wondering what could be causing it? I was told to switch the PCV valve but when I checked, there wasn't one (just a hollow elbow) I went to the local dealer and they said that 92 wranglers don't have pcv valves. First is that statement true and second if so what else can I do to reduce the oil/gas going into my air filter, as i can't imagine that it is any good?

well not sure why its doing that, probably bad rings and your getting oil blow by, but, yes 91-current don't use PCV valves.

I have a 92 and it did the same thing. Mine had really poor compression. One cyl below 80lbs. The highest was 120 and they all varied.
