Answer: There are two ways.
I know that problem. It took a while to learn why it's not always a gasket problem - even tho oil leaks past the gasket and settles around your spark plugs. Here's what I found to end the problem. Stay with me here... during the explanation. I feel that knowing the reason and the remedy will end your seepage problem and give your car more like-new power again. This method keeps other problems from occurring. It stopped my leak, and it did all that, too.
The Ford oil leak oil seep problem is caused by something called blowby. Blowby is combustion gases forced past the sides of your motor's pistons, which mix in with your motor oil. Blowby is always present and becomes an engine problem when engine negatives rise. I'll show what they are and my tip to end their leak trouble
Normally, blowby creates about 2 to 3 lbs of of air pressure in the crankcase, which includes the top part of your motor where oil can leak past seals and O-rings. Because blowby is harmful, by design is constantly recycled through a relief valve to maintain crankcase pressure at 3lbs or less.
But problems arise over time, and oil issues result from increased blowby pressure, its acidic nature, and its contribution to oil breakdown. Those conditions grow over time, causing your leak and eventually wearing out your engine at 100,000 miles too soon.
Blowby adds to oil's breakdown, meaning, it turns oil back into tar with the help of other engine negatives like high temperatures, acids, and oil's natural breakdown. The resulting tar-like, acid film coats every part. You change your oil, but oil, in most cases, cannot remove those tar-like residues and oil's leakage.
Getting rid of those villains by cleaning is the way to stop oil sep page.
While gaskets and seals do stop oil's escape, those engine villains of acidic shrink seals and gaskets, and higher crankcase pressure allow the oil leak problem. Other villains...
Two other villians to remove are motor's raw touch points result in frictions 2000 degree internal hot spots add to a rise in crankcase heat pressure. Anti-freeze breakdown layers a film over the coolants of scum to blanket and slowscum acts as a blanket blocking heats transfer to the outside air.
Not so however, when sticking holds-in your piston rings in their slots and leaves open the gap for much more combustion to escape. Doing so drops power out-put, as you can imagine, and causes your leak. Sticking keeps your motors 12 to 24 piston rings from flexing outward to seal-off combustion. Anyway, being dirty and sticky, rings seal less and allow more blowby to fill the crankcase. This increases sludge, causes valves to tap, drops power out put, increases friction, sucks-up oil and burns it out the tail pipe - you get the idea.
The thing is that excessive blowby increases crankcase pressures to 10 to 15lbs - and that triples the normal blowby pressure. Higher pressures forces oil to leak out around your valve cover gaskets - and other seals, as you now experience. That is why it may not be a gasket problem entirely. Does that make sense to you?

You could tighten the gasket cover - but that does not end the real problem - a half turn tighter on the cover nuts is good. Do that! You could do a $2500 overhaul - which replace old rings with new, to end the problem. I prefer several Mega Power Brand products package as a treatment that quickly frees sticking piston ring problems in a day of driving. That product frees sticky rings and that drops the crankcase pressure back down to normal. It keeps crankcase pressure low that way. That ends such leak problems at its cause, but for under $100. I think its the best way to do so.
