Any idea where this leak is coming from? Pic is of the back side of the block.

Left rear or right front is common for head gasket oil leaks. Possibly maybe leaking from elsewhere but running along the head gasket hard to know though.

Cam cover for the valve cam leaking and running down? Are you sure it's oil ?

Here’s a couple of videos of the leaks the engine has.The one around the rocker cover and jake brake harness and exhaust manifold rear have been there for a minute.The one behind the engine is three weeks old,and the one at the top of the oil filter housing and front of EGR cooler is a week old.

Personally, none of those leaks would bother me in the least. Just looks like a little residue not oil spewing out and losing a gallon a week or something like that. Old engines are gonna leak a little, that's just the way it is.

Yeah it just sucks to see them because I prided myself on having an almost leak free engine.The rocker cover and engine brake harness were bad enough for me but it seems like this cold in North Dakota has made everything leak lol.
