Oil leaking from glow plugs

I have found the culprit of my oil leak. Traced it up to a glow plug on the passenger side. Anybody else had this problem?

Just wondering, how does a glow plug leak engine oil? I thought they were installed in the combustion chamber. You sure it's not leaking fuel/combustion residue?

Not sure. Definitely not a mechanic here just going off what I see. Guess it could be running down from the valve cover?

They mean that wiring harness that sticks out through the valve cover.

^^^ Yes.

The glow plug is about 2.5" past the valve cover. DO NOT try and take them out of a 6.4 unless you have the sleeve to do so, unless you wanna take the valve cover off to fish it out when you drop it.

The harness just pulls out, but you need a special tool to do it.
