I'd change your oil filter to the Ford one I believe it has a valve to prevent flowback.
Just a cheap easy thing to try
Whats a VCT? yeah but we've had the car new since 2004. why would this be happening now? i will give it a shot though.. i'll hit the stealership up next time i change the oil, which will be soon to pick up the ford filter.
