2000 Rodeo

I have had this problem for 2 years and no one can seem to fix it. I have oil leaking into my number 1 and 3 sparkplugs. The valve cover gaskets have been changed three times and the problem is still there. Can anyone help me with this. I have to clean or change those two sparkplugs about every two days for it to run right.
It is a 2000 Rodeo LSE V6

the problem isnt just the valve cover gasket its gaskets in the tubes that are causing your problem

I have also noticed oil on 1 first plug. How to fix it?

the valve cover gasket has been changed along with the round ones at the top and i bought new boots (rubber things that run down the well) for those two sparkplugs. What gaskets in the tubes are you talking about.
Thanks

When is the last time you changed out your PCV?

I just changed it yesterday. It is running fine right now but I also cleaned the spark plugs too.
