I have a late 04 my oil cooler went out and sucked all the oil into my coolant and went into limp mode on my wife and she drove it home anyways so when I got home I put a new oil cooler egr cooler stand pipes dummy plugs hpop ipr lpop and front cover because something went through it so now at idle my oil pressure drops to nothing I put a new switch in it and no luck so I put a manual gauge on it and it shows 5 pounds. after hours of searching the only thing I can come up with is bearing clearance I did put new oil and motorcraft filter does anyone have any other thoughts thanks in advance
