oil filler cap

thanks for all of the input. For more info the oil looks new as well as the filter. The plugs are not covered in oil. When I first started the car I had a problem getting it to run so I pulled the plugs to replace them and the 5 and 6 cyl plugs looked wet with water so I thought the head gasket was shot. The oil doesn't show any sign of water. I'm not loosing any water from the radiator and they look dry now. maybe condensation from sitting in Fla. I took the hose from the pvc valve and blew it out with air and it didn't seem to have any restrictions. The carb doesn't seem to have any carbon buildup. I tried RedFish's idea with the drill bit and it came out clean. I haven't added anything to the oil yet to clean the engine and change the oil as was suggested. Maybe I can try that tomorow, but I've been working on the body while we have had temp in the upper 70's the last couple of days.
Thanks again for all of the ideas. Hey, why don't all of you guys just ride to the Carolinas. I'll bet we could get it corrected in no time.
