Engine oil leak left side of engine

[Outsider6.0]

I recently developed an engine oil leak on my 04 f250. After spending several hours crawling around under the hood I think I have pin pointed it to the left side glow plug buss bar. I'm not losing large amounts of oil but I want to fix it before it becomes a real problem. So I guess my question is, is it possible for
Oil to leak from there, has anyone had this happen before, and how easy or
Difficult is it to repair.

YES they always leak and they can either cooperate or become a bastard.

All you need is a handy dandy trim panel tool thats got a good opening and pry them out. If they break NO PROBLEM! drill them with a small bit CLOSE to the edge to cut the rubber O ring and then what i do is use a sturdy pick for cotter pins and try to spin and pry them out. Usually i get them first shot drilling and with a pick sometimes i end up going midevil on them and use a punch and break the plastic up with a punch and use a vacuum to get all the debris out of the top of the cylinder head.

oh and make sure when you install new ones use a good grease on the O rings. I like to use red Valvoline grease.

Thanks for the help guys, that's a load off me racking my brain and trying to figure out how to do it.

the easiest way is to remove the inner fender well 5.5mm socket 8mm socket, and then i just unplug the glow plug harness and pry the glow plug harness out.

they are really easy to take off, may want to think about slapping a new set of glowplugs in on that side, they are relatively cheap, should be able to get 4 of them for like $30-40. swap out the o-rings, and there you go, no more leaks.

why replace them if they arent shorted out?
