Not sure if you posted a photo, but it didn't come out. I had a lot of problems with valve seals on a Nissan once, they were aftermarket. They kept popping off of the valve guide and would ride with the valve stem and not seal at all. Car used a ton of oil. Pop the valve cover and look for any seals that look like they are not down all the way. Have you contacted Brian about this (I see you have TEA heads)? With aftermarket springs, they are likely running the pre-2002 valve seal design, which is a press on fit.

I didnt call brian but the seals look seated real good. i did buy some aftermarket seals from TR to see if that fixs the problem, just wondering if anyone else had this kind of problem and what they did to fix it. i actually had oil on the spark plug wire too

Now oil on the plug wire, could be from a nick in the valve cover gasket, or worst case through the plug threads. How bad does a plug look after 30 miles or so? Plug go in the threads with good feeling, or is it pretty loose?

Guess I am confused, where is the oil on the spark plug, on the outside or inside the combustion chamber? If its the outside, I would check the valve cover gasket. Which spark plug? If its number 2 or 4, then also check you PCV hoses and make sure everything is on correctly.
