I just relaced the upper intake manifold on my 2003 4.6l. It went O.K. but now 2 of my injectors have oil leaking out of the injector port and all over the injector ! I swapped injectors to see if they were clogged but it still happens on only those 2 injector ports. Been working on mustangs a long time, had a '79, 82, 98, and now 2003 but this one has me stumped ! Any ideas ?

 

Do you mean the oil is on the tip of the injector when you pull it out?
