I just got a 90 YJ and drove it 15 miles before my valve cover gasket went pop. found out that the PCV valve was original, and stuck in the valve cover, it was also plugged, and the crankcase pressurized and blew the gasket. Oil went everywhere, and I still have a mess to clean up! Pretty common when the engine has some blowby. Had this happen on a 454 V8 once when some wasps decided their nests would be great in the breather tubes...
I don't know why, but I just can't NOT own a jeep...
