ok so here I go, I was looking at replacing my valve stem seals because I burn a little oil every once in a while when I sit at an idle for awhile, then take off. I got down to where I took the spark plugs out and there is no sign of oil on any of them, and I tested the PCV valve and it is almost completely clogged, my question is do you think it is possible that the seals are okay and I just need to replace the PCV valve? cause that would save me a lot of work that I don't really have time to do. Also any recomendations on spark plugs for the 3.5? since it is a good 3-4 hour job just to get to the plugs.
