Oil filter leak
99 Super Duty, 5.4 Automatic 4x4
Here's my problem, I changed the oil the other morning, drove it to town to run some errands, and on the way home, bout a mile from home, I started smelling oil. Got home and shut the truck off, looked under it, and there was oil slowly running off of my oil filter. Crawled under and made sure it was tight, wiped it off, and it was still leaking. Bought another filter today and put it on, and at first it didn't leak at all, shut the truck off and checked the oil level, started it again, and here comes the leak again.
Any idea's on what could be the problem? I made sure the housing was all wiped clean, both times I put the new filters on. I can't see getting 2 bad filters in a row, I even went so far as to get them from 2 different places.
Any help would be appreciated.

yea did you double gasket it? If you did you are one lucky SOB! They usually blow all the oil out IMMEDIATELY if they are double gasketed.
Get under there, pull the filter off, then clean the housing and make sure there isn't a rubber gasket stuck on it where the filter goes.

I know it is not double gasketed, as the filters that I have taken off of the truck all have the rubber gasket on them still. Also, both times that I have put the new filter on, I waited till all the oil had drained off, and wiped the housing perfectly clean, paying particular attention that it had no dirt or anything on it before I put the new filter on. I also made sure to lube both of the new filter's rubber gaskets before installing them. I made sure to spin the filter on by hand, till the gasket contacted the housing, and then an additional half turn, just as I have done to all the vehicles that I have ever changed the oil on.
So what gives?

Your oil cooler adapter may be loose. If there are lines running from the filter mount, they are hooked to a cooler. This "adapter" per sey, is heldon bu a large allen-headed bolt. Once you remove the filter, look up, into the center of the adapter and you will see the bolt. Tighten this bolt.

Not that it should matter, but what brand filter are you using?
I use the Motorcraft (FL820s) and if I recall...it says to hand tighten and then give it an extra 3/4 turn...and not the 1/2 turn that you are doing.
Hope this helps...

If you look at it and don't find anything wrong just tighten it up more. I've had this happen before and have even had to put the wrench on it to crank it tighter. It won't hurt a thing (other than making it harder to take off) to tighten it on down. Sometimes they even loosen up later if you don't tighten them enough to begin with.

I've had problems with leaking oil filters also on my 2002 F250 5.4, twice with a dealer installed Ford filter and once with a Fram (worse). I do my own oil changes since off warranty and I'm presently using Quaker State filters with no problems at all. I think the problem lies with the gasket material, you can feel the differences. The Quaker filter has a harder and smoother gasket as compared to the Fram which is soft and "rougher" If for no other reason I won't use Fram filters anymore on any of my vehicles after noticing seepage on my '89 5.0 also.

You stop short of saying that you visually verified that there's no old gasket left in. I'd do two things right off. Get a good flashlight and actually look into the area where the gasket goes, and even go so far as to slide another gasket up into that position so there's no question that the old one(s) are gone.
Also, look carefully for debris in this area hat might be deforming the gaskets.
