Does anyone know where this oil leak could be coming from

[Dhollis15]

I have a pretty decent oil leak coming from my dodge ram I’m seeing a lot of black oil build up down around the plenum and the fuel injectors does anyone know where this could be coming from

Is that an expensive fix? how would I know that was the problem

need to remove the intake manifold, or might be able to get a borescope camera under it to look.

Degrease it first ,then look for it. Could it been someone spilled it when they were adding oil ?
