Which manifold is black and gummed up? It it's the intake side you could have a bad PCV valve, or more likely the EGR is doing it's thing...

Decided since the weather here is turning nice again, I can park the Eclipse for a bit and use my motorcycle. Today tearing into the engine bay. Replacing the intake manifold gasket and some exhaust gaskets. The inside of the manifold is all kinds of gummed up and black. Like tar. I’m sure it is oil. I’ve been driving it for a bit now, and also found what looks like a rear main leak. Will cross that one when I get there. Going to clean up the bay as I go, knowing it will be pointless but it’ll make me feel a bit better until I have to do it again.
Almost no oil in the charge pipes. More of a thin oily film. Definitely leaning towards PCV system. Have to replace all the couplings on the turbo system though, some are cracked, and others are just nasty, or just a bit too big and clamped as tight as they could.
