more info is needed on this, but I'll try to help you I will assume that this may be a 4.6 Romeo/ Windsor motor and if it is the oil pump is behind the timing cover and would not show a visible leak unless there is oil leaking from the cover gasket this would be the problem not the pump/next if you jack up the car put it on jack stands safely and look under it at the bottom of the engine there are a couple of things that could cause the leaking oil (1) oil filter loose/or to tight if there is oil all over it clean it off with a rag and let the motor run with the oil at the proper level if its loose or a broken O ring on the filter you will see the oil coming out if so change the filter and tighten till a good snug fit is achieved (2) the oil sender unit could be leaking oil from it this sender is screwed into the oil filter adapter and has an electrical plug on it the sealer on the threads may be leaking and can be fixed by cleaning and applying new sealer or the sender may be bad and needs to be replaced is the oil light coming on steady or on and off at times (3) if you clean everything off and then take baby powder and throw it all over these areas the leak will show up in the powder if you can't find it , if you see oil and antifreeze the green stuff leaking from the same spot behind the oil filter the adapter gasket is leaking be careful here because your cooling system can be clogged causing this gasket to leak go slowly and post back to me what you have done a step by step procedure will narrow this down to the cause I'm a taxi mechanic in N.Y.C. and 4.6's are what the crown Victoria's and Lincoln town cars have it's the same motor you must tell me if this is your motor if not I will still be able to help you further good luck in your search for the leak and do it safely a good jack and stands no junk stuff you'll be under the car and need assurance that you will be safe LATER MAN!
Check the oil filter. The old gasket might be stuck on the engine (two gaskets stuck together), or the new gasket might be defective, misaligned or missing.
Has the oil filter just been replaced? Sometimes the old gasket sticks to the mounting area, causing leakage if the new filter is installed on top of it. It is also possible the gasket was for some reason missing on a new filter. Let me know if this is not the cause, I'll try to help further.
there is a gasket on the oil filter .... upon removing the old filter you have to make sure that the old gasket came off .....if not then it stayed stuck in the filter housing . if the old gasket is there , all you have to do is pull it off with pliers !!!
If it's leaking from the oil filter spacer.( the 2 inch metal ring that attaches to your block, and has two rubber hoses coming out of it, and your oil filter attaches to) There is an o-ring between the spacer and the block. Take off your oil filter, remove the oil filter stud with 1 3/16" socket( or metric equivalent) and the spacer will come off. I found all the auto parts stores around me said that the o-ring was a dealer item. I bought a FRAM PH3387A oil filter and removed the o-ring on that. It fit perfectly, snug down your oil filter stud to specs, then install your oil filter. Double check that the oil filter is not double gasketed, and your are fixed!
It's not the oil filter leaking it's the housing that holds the oil filter?
