Hey guys, new to the forum. I am currently getting ready to fix up my jeep that has been sitting the last two years, i popped the hood today and noticed that there was oil seeping through the top PCV valve as well as valve cover. I was just wondering what would cause this since it has not been started for 2 years I will be replacing all the gaskets just wanted to know if that is normal or should be looking into something more wrong with it, thanks
