    Thank you, Mike! I followed your very clear instructions and finally stopped this nagging oil leak on my 2003 Expedition. As I expected, it took me about twice as long as you to complete it, but that's okay as I can't imagine what the shop would have charged. Plus, I got an oil change and radiator flush out of the deal. The only tips I would offer are to get a strap type oil wrench because that filter is hard to get to, and be careful tightening the radiator plug; it's plastic and breaks easily (as mine did). Thanks again! I can finally park in my friend's driveways again.

OK, I just did this on a 2003 Expedition. Really not that hard at all - took me about 1.5 hours.
You'll need a new gasket ($12.00 at AutoZone), a jug of Antifreeze, a drain pan (large enough to hold all of the coolant - roughly 3-4 gallons, another pan for the oil). A ratchet with a 4 inch extension and a U-joint(knuckle or swivel socket). A 1/2 in. socket for the adapter, and a 3/4" wrench for the radiator drain plug.
First, I pulled the car up on a pair of ramps - remember, you'll have to drain the oil and coolant before you remove the adapter. The incline of the ramps does not hinder any draining of the fluids. Also, remover the oil filter - might as well change your oil while you're doing this just in case the coolant and oil have mixed due to the leaking gasket. Wipe everything down real good, I'm sure you'll have alot of resudual oil splattered everywhere. You want it clean so that when you're done, you'll know the problem is solved vs. not being able to tell because of all the (old) oil.
OK, so the oil is drained, plug replaced, and the oil filter is removed. Now, drain the coolant. The plu is very easy to find, on the fron, left of the (bottom) radiator. Use the 3/4" wrench or adjustable to open the valve. There is a place to attach a 3/8" hose but I just let mine gravity feed into a pan - Open the coolant resevoir lid on top of the engine to vent and allow it to drain faster. This should take about 20 mins to drain.
Tighten the coolant valve (don't overtorque)
Now, slide back to the filter adapter - Unplug the electrical connector (push IN with a screwdriver and pull out), next, you'll need to take the bottom hose off the adapter. Use a pair of channel locks or pliera to squeeze the clamp in to allow slack in the hose to slide off - it's tight, so take your time! You don't have to take the top hose off.
TIP: stuff a small rag in the hose you just took off, it'll keep antifreeze from dripping on you while you're under it - remember to take it out!!!
I started with the hardest bolt first - the one closet to the front, you'll know it when you see it. To get this loose, you'll need the U-joint on 1/2" socket and an extension. There are 4 bolts total, not that hard, just takes a little time.
Once the bolts are out , it's easy to pry down on the FA to remove the gasket. Simply slide in the new one (it'll only go one way, don't worry about putting in backwards or upside down). Put one bolt in the fron and back and handtighten the bolts, this will start lining up the holes. Next install the other 2 bolts, handtighten each a little at a time so the gasket will center itself. Once it's seated, tighten the 4 bolts - not too tight, it's aluminum remember! Plug the elec connector back in.
The gasket I removed didn't really show any signs of deterioration or anything.
Now you need to reinstall a new oil filter and top the oil off. Also, refill the coolant - the directions are on the back of the jug.
My biggest tips for this job are: Have a few towels/rags around - you'll spill oil and coolant, Capture and dispose of the coolant/oil properly - remember, pets love antifreeze, but it'll kill 'em. Again, clean all of the residual off the frame, oil pan, hoses - that way you can tell if the job worked, or if the leak is in another area.
Good Luck - you can do it!

We performed exactly the same repair on December 28, 2010 withexactly the same outcome. Finding no other references to this oil pressureproblem anywhere on the internet and the fact that they both happened the samemonth, I can only wonder if there are some incorrectly made gaskets hitting theshelves.

Make sure you clean off old oil where oil filter seats

How to change the gasket on the oil filter adapter


Easy fix I just did. (replacing the oil filter adapter gasket which is a common leak). Remove the air cleaner tube and housing. Release the tension on the belt. Remove the two front bolts on the air compressor. They are nuts but the stud will come out too which is fine. Under the car loosen the third air compressor bolt. This will give you enough room to loosen the hidden bolt on the oil filter adapter. It only needs to be loosened as the adapter is slotted there. Remove the other two bolts on the oil filter adapter and remove. Replace the gasket and install.

Oil leaks from the oil filter adapter


If it is not the suggested gasket that is leaking then it is the oil pressure switch located exactly above the oil filter adapter. The black plastic housing could have developed a crack and oil will ooze downward and drip off the bottom of the adapter. I had this problem and changing the oil pressure switch took care of it.

`1992 jeep cherokee lorado straight inline 6 oil leaking from the where the oil filter attaches to the motor


I'm fairly certain that the parts stores carry the oil filter adapter gasket. Check around for it and make sure both surfaces are very clean. I like to use a FILM of sealant on both sides of the gasket and install. The reason why you use the sealant is to compensate for any irregulatities of both surfaces. You also might want to install a new oil pressure sending unit to the adapter while you have it off. That is another place where you could have a leak. They like to wear out prematurely also.
