While trying to figure out what was cause the other issues with this car, ended up fixing something for a change. the oil in the intake was coming from the pcv valve even though I changed it it was not a oem kia pcv valve they are calabrated to each vehicle. (as per kia ) I also change the valve cover gasket cleaned out the years of neglect in the cover. changed the vent hose located on the back of valve cover going to intake tube. replaced oil soaked air filter, and so far so good.
