your are right about about a lot of muck for sure!but lets say ford in all their wisdom cheated and uses this muck to wash the valve ? (I am not even close to being a mechanic but the fuel amount they are catching is suspect no?)
is it going to the crank case or being ignited ?.if the catch cans job is to stop it from collecting on the back side of the intake valve its going to get burned no? is the catch can before or after the stock separator?
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!!
ford sells millions ,yes millions of Eco boost in different forms. you are on point with your reply . I worry about FRAME rust here in CT way more than intake valve carbon.step on the gas now and then from day one an you will be fine. Drive like a Oldman for short trips any engine is going to...
