I noticed a fairly serious oil leak on my 2003 P71 about a month ago, it is a very (at least to me) strange leak. I check the oil about every 3 days and its not losing enough to stop driving the car but it is getting annoying and starting to make my driveway ugly. Every time I check the oil level it is in the same spot, but I know the car is bleeding. So about 2 weeks ago I idled the car and took a few pictures. Hopefully someone else has came across this type of leak. I don't know the source. But I do know it can lead to something serious if I don't track this leak down.

When I first got under it this kinda made me worry








after about 35 minutes of idling this is how much it leaked

Oil cooler hoses? Hard to tell from that angle, I am sure someone else will be chiming in...

You have to degrease/ wipe all the oil that has been spread around under there and try to pin point the exact location. I would venture to say it's probably the oil cooler hose though.

well if the oil level isn't changin and you haven't added any.... have you checked your transmission/power steering fluid. i blew my p/s pump out on my vic and it was that bad aswell and looked like oil at a first glance until i could see the red tint. otherwise my suggestion is clean everything off, get some dye from your parts store and look with a uv light to find the primary cause.

I wiped everything down, but I didn't degrease. It's not transmission or power steering fluid, it's oil for sure. The dye is a good idea.

Looks like a leaking cooler hose or filter adapter, pretty common and easy to replace the o rings.

http://www.idmsvcs.com/2vmod/oilcooler/index.html

The part in red is your oil pan and may be a seeping pan gasket, front cover gasket, or rear/front main seal. Doesnt look too bad though, they usually are pretty dirty.

the lines are your oil cooler lines, specific to police and rare on other models. the thing circled in green is your oil filter adapter

oil is pumped into the oil filter adapter before going though the engine, ford uses the oil filter adapter(which also functions as the water/coolant inlet on the 4.6sohc and other modular v8's) so that they can build 1 engine block, but use different adapters on different cars to position the oil filter, coolant inlet, and oil coolers(if equipped) to suit the specific vehicle such as f-150, mustang, e-150, ect.

I had engine oil leaks that would lose approx 1qt engine oil per 2500miles

the oil cooler lines are often to blame, but half of the time they are leaking from the o-ring gaskets that seal them as they enter the oil filter adapter/oil cooler. some users have found replacement of just the o-rings to fix the leaks, and silicone o-rings are recommended for better heat/oil resistance.

I decided to do everything, first I ordered the cooler lines(Dorman though NAPA, 2 days out) then when I received the cooler lines I removed the rubber o-rings and had NAPA match the rubber o-rings to silicone ones, there are two o-rings at each of the 4 ends of lines for a total of 8 o-rings.

replacement of the cooler lines is very simple, if you can manage to change your own oil you can handle this, it is suggested to do it at the same time as an oil change for convenience, but you can change them whenever. simply remove the 7mm or 8mm(I can't remember) from the plate that holds the lines against the oil cooler, and again at the oil filter adapter. gently pull the lines away from the cooler/adapter, about 1-2qts of oil will drain, have a pan ready. clean up your mess, and simple shove the new lines into the cooler/adapter, be gentle not to damage or mess up the o-rings during installation. re-bolt the new plates to secure the hoses. if changing the oil, I find that draining the cooler lines will increase oil capacity 1qt, so when finished top off the oil, or if changing the oil approx 7 qts will be required, 6rqts for 02- 4.6 panthers.

after replacement of the lines I still had some oil loss, with oil around the same area, another common culprit is the oil filter adapter gasket, which goes between the engine block and the oil filter adapter, and seals in oil and coolant. replacement of this gasket is more tricky, I believe it is attached with 4- 12, 13 or 14mm bolts, most of which will require extensions and u-joints, the oil cooler and filter will need to be removed, so this is also suggested to be done with an oil change, additionally you will need to drain the coolant before you start. once the adapter is removed, you should clean the gasket surface along with the gasket surface on the block, some people have either added or removed the oil cooler system(for preference) this way by getting the opposite oil filter adapter at the junkyard, I have never heard of this piece cracking or breaking. install new gasket with adapter, fill oil and coolant. try not to get coolant in oil or vise-versa when the adapter is off.

after I replaced that gasket I had no more oil leaks and oil stays full throughout my 2500 mile drain interval.

oh and my oil pan looked like that too.. the oil went all the way to the back of the oil pan. I sprayed it all down with brake-clean after I did the gasket, no more oil on the pan, I believe it was coming down from the adapter gasket.

and I believe the blue arrow is a power steering line. appears that nothing is wrong with it.

my leak/s were not as bad as yours, but I too had oil all over the steering rack and sub frame.

oil filter adapter gasket 5$
oil cooler lines 20-50$ aftermarket
(8) silicone o-rings 6$

oil and coolant and labor

keep the questions coming.

I'm hoping to replace oil cooler hose soon because it was replaced back in May of 2009, most of the belts and other hoses were replaced then also, so might get those about of the way also.

Is it possible for the oil cooler adapter to have a crack?

The cooler lines should not be going bad every couple years, U should really try the silicone o-rings they'll last much longer.

the oil filter adapter is aluminum, so yes it is possible for it to crack, But I have never heard of such an issue, and the coolant stays below 20psi and the oil below 80psi, which I doubt is enough force to crack the piece.

Who makes the best o-rings? If there's such.

I've never really heard of any brands, I just wouldn't go out and get cheapest o-ring, any silicone ones will be just fine. cheapest-silicone > best-rubber IMO
