740 Madness -

I just completed replacement of the oil trap, and wanted to add a couple of observations:

Fuel rail disconnection...

Where the fuel hard line has a joint in it, I don't think this a quick disconnection fitting, but rather a joint that only allows for rotation of the hard line. When I pulled the fuel rail from the manifold, that joint allowed me to turn the rail upside down, and then remove some torx head screws that hold a sheet metal bracket on the back of the aluminum fuel rail that secure the injectors and the fuel line input fitting (a 90 elbow that is connected to a short piece of rubber hose that is connected to the hard line, downstream from the hard line joint). Once this bracket is removed, then the 90 elbow can be removed (and the injectors too) thus getting the fuel rail out of the way to remove the intake manifold. Then, after the bolts on the intake are removed/loosened, then I tilted the driver's side of the manifold up and snaked the fuel hard line and vent hose through the manifold. Not too difficult, but it takes some patience.


Throttle Body...
I removed the throttle body to give me extra wiggle room, and to clean it. I cleaned the inside of the manifold with solvent (Chemtool) and cleaned the intakes on the block which were a dirty too.

Overall...
I got the manifold off in less than an hour, the oil trap was replaced in minutes, and the manifold went back on easily, once you know the tricks of removal.
