Oil filter housing
Hey all,
Does anyone know if the oil filter housing on 2006 PSD drains down after turning off the engine? Mine is completely empty several minutes after shutting down. I have been experiencing long crank times and I am trying to eliminate potential reasons. Thanks in advance for any help.

How do you know it's empty a couple of minutes after shut down? If your using OEM filters it shouldn't drain after you shut it down....the correct filter will keep the drain closed in the bottom of the filter housing.

I removed the filter cap the other day and the filter was very dry and just a trace of oil was at the bottom of the housing. I ran the truck and then shut it down and let it sit for a few minutes. After removing the filter cap the filter appeared to have been drained already for several minutes. I could not get a confirmed answer if the filter housing would drain prior to removing the cap. From what I have read the filter drain cannot be replaced without the entire housing being replaced.

It's not in the housing, it's in the filter base. I know that much anyway. The filter housing is nothing more than a cylinder, open on each end. The bottom sits on the base and the top is threaded and machined for the cap.
I can't say what the filter base consists of, because I didn't have to get in it that far.

Another good question besides OEM filters is are you positive you have an OEM filter cap. Some non-OEM filters come with a non-OEM cap that a previous owner might have used.

Is it possible you have the right filter under a cap off an aftermarket filter? I know some of the aftermarket caps are 1/4in or so taller and would not seal properly with the Motorcraft filter. Just a thought.

Positive on the filters. The truck is cranking longer then it used to and I noticed the dash oil pressure gaug don't read any pressure until the truck has been running for 2 to 3 seconds. Other then the long crank the truck runs great. I have been doing a lot of reading on the long crank issue and have already home checked the ficm and batteries have been load tested. Just a note; when I removed the oil filter after the truck had been sitting over night you could not get it to drip oil at all. I appreciate all the responses and encourage any ideas.

Sounds like I have to look into replacing the filter housing if the drain valve itself is not replaceable. I did manually push the valve down when I had the filter out and it seemed to operate correctly; however, I can't tell if it is sealing.

Does anyone know if I take the filter out and press and hold down the drain valve while pouring oil into the housing will it drain for some other reason other than a defective oil drain?
Just a thought. What do you think?
