It might be a bad PCV valve, they run about 10 bucks. It be worth a try.

Hmmm. no recall if it's a 4.7L it's the PCV in the oil fill neck or there are two "Breather" tubes one on the rear of each cylinder head they will gum up and do the same thing.

HI If its not pcv valve . or most likely It can b a bad ring or valves seals that gives a blow buy and pushes oil in filter .You can check for blow-buy take the pcv valve off when engine running to see if there's is back pressure through the hole . Good Luck. Lionel
