Interesting. It keeps the valve seats oiled up but also builds up on the valves which eventually makes them stick. Huh... This topic has been beat to hell and I'm still torn.I read a ford bulletin on a 2.7 forum ford telling their techs a certain amount of oil blow bye is not only expected but helps with the life durability of the intake valve seats!!
