Oil leak behind the cam

Thanks TMM, the visual helps me understand.

Hang on a sec; you see that bag of pipe plugs? Any chance they also are "extras",lol? You know that at least a couple of them belongs inside the engine, right?
And missing them will cause catastrophic engine failure.
And don't forget the tiny cup plug that goes up into the galley from the bottom of the engine to seperate the oil into two paths; the first is to the filter and the second takes filtered oil into the rest of the system. If not there, your oil will not get filtered. I can just barely see the cup plug in the bag..........
And there is another plug in the cavity behind the oil filter, don't forget that one,lol.

Normally thoses two small plugs that come in the kit are for the oil galleries behind the cam retaining plate aren't they.

Now I don't want to beat a dead horse regarding the plugs, but is there any reason a shop would remove those to get the camshaft and cam bearings out? I'm just thinking that they're still there. The only plugs I used from the kit were the plugs I removed (aside from the cam plug, which is now installed). Does that make sense?
