Well do you have a minor oil leak. That you can not find. Well on the passenger side of the engine near the firewall. There is a brass fitting ontop of the valve cover this is a plug for the HPOP system. Well there is an O-ring that seals that brass fitting. You need a 5/8 wrench to remove that fitting. Then if the O-ring doesn't come out with the fitting a small flat head screwdriver will get it out. Then you replace that damaged o-ring with a new one. Put a little motor oil on the O-ring so it will not get cut during install. Then reinstall that brass fitting.

I had an oil leak for 3 months that I could not find. I knew it was coming from the top of the engine. Well I found it being that 2 dollar o-ring.

 

ive never changed one but the ford house did on my 02 about 20 times, along wilots of other crap , i tried looking the first time for about a weak and said forget it, great info though wish u would have posted this about 3 years ago

 

Was That The Fix For Good? Or Did It End Up Coming back?
