Oil filter housing empty

[jlfq2]

My truck has been sitting for 5 days.I went to change the oil and decided to do it on a cold engine to see if I got more or less oil out compared to warming the engine up first.Anyhow when I took the oil filter cap off and pullled the filter there was very little oil in there like it had drained before I Loosened the cap.I usually change the oil when the engine is warm and have to let the filter drip a little before swinging it over the engine.Everything looked fine down in the bottom of housing where the drain valve is.Anyone ever heard of this before.

Is there a Genuine Ford filter in there? Some aftermarket filters will trip the drain valve and it will empty when you shut it down.......

Yes Motorcraft filter

I would start it and drive it. Get it to operating temp and shut it down. Wait for 10 minutes and pull the cap and check it. May have had something in the valve.

I don't understand how these filters work. All the crud goes to the top and into the filter then when you go to change the filter all the crud goes back in the engine. Or in this case goes back when he turns off the engine.
