I think you're onto something... zooming in on the posted pic, there does not appear to be a hole in the pictured nipple, just an indentation.Maybe someone could look under his hood and tell if there is a hose on it or not.
I saw a video from another Explorer that also didn't have a hose on there. This thing seemed even not to have a hole.
That is the bolt for the valve cover.
Thank you. You are absolutely right!That is the bolt for the valve cover.
I dont have deep wells in every size, actually just oneIt’d just be a deep well socket on a regular torque wrench
Each valve cover has three of them. And also three "normal" ones.So are all the VC bolts like that or just this one and (some or all of) the rest lack the nipple?
Doesn’t make it less weird.Each valve cover has three of them. And also three "normal" ones.
