OIL IN THE AIR

Mine did this (and probably still does). It could be a clogged PCV valve, but more likely it is just a worn engine. I think that there is supposed to be a vaccum in the valve cover, so that air is drawn in through the carb, into the back of the valve cover, then out through the PCV.
I "fixed" my problem by buying a breather cap from Pep Boys. It is just a crome thingy that looks like a mushroom. That way I keep the oil out of the carb

For your information:
I had a similar problem with my YJ258 that might help. There are two large hoses on the valve cover, the rear one is from the cover to the air cleaner/box and the front one is from the cover to intake vacuum, with a pcv valve installed at the cover. My problem was a lot of oil was ending up in the air cleaner/box. The solution was the valve cover/pcv/vacuum hose had a small orifice inside the middle of the hose(that I couldn't see until I removed the hose) which was plugged and eliminating vacuum to equal the pressure inside the valve cover which caused oil to blow through the rear hose into the air cleaner/box.I sprayed carb cleaner through the valve cover/pcv/vacuum hose and NO MORE OIL! INSTANTLY! P.S. I was told I needed valve jobs to a complete engine. Sorry, all it was was !1.99 can of gumout.A year to find and a minute to fix, and that was about 60,000 miles ago!
