Oil leak front of engine

My 5.9 just started leaking oil front the front of the engine and looks to be starting about half way up and only really leaking on the front right side.

Is that looking at the engine or looking away from the engine? If it look slike it coming from the front main sela and dripping offf the AC compressor on the passenger side of the engine it is likely the dreaded accessory cove r leak under the fan mount.Driver sides are the same, accessory cover gasket has broken usually behind the CP-3.

I'm going to clean up the area and take a look at it while running and get back to you on it.

I've seen more and more threads on this lately and I'm definitely in this boat.
Dreading this repair but I'm going full boar and pulling the oil pan too. Parts came in, now just waiting for access to a cherry picker before I get started.
I'm ditching the gasket between the timing cover housing and block and going with "The Right Stuff".

I don't want to have to do this again...ever.

That is the passenger side of the engine, right side from the rear. The source of that leak is usually under the fan mount.

Cleaned up my engine and I dont have any oil spurting out while running but it does seem to be leaking from the top of the timing cover. Guess it's good I have to replace my rad aswell.

I mean it's pretty rare to have it come from the top of the timing cover, usually those ones directly on the front are from the crank seal. If it's from the top area, it's usually the timing housing (interface to engine) on the slope leading down to the passenger side. Around the water pump area. The gap between bolts there for the housing is larger than everywhere else and the gasket will fail.

If that's the case, most will just smear some sort of RTV in the crack where it's leaking and call it a day and have had good results with no leaking for many more years. Sure beats pulling the timing gear housing...
