Wow. I hadn't thought about that and also am a bit leery of a brass manifold and engine vibration.
The back of the head is a nice idea but not so nice if something goes wrong with that connection in the future. I might split the feed off the back of the block and run a second flexible oil line to a remote manifold not mounted on the engine.
Food for thought and if I wasn't sidelined with a 700 mile road trip yesterday to get a propane tank and the installation of that in the next few days, it might get done real soon.
I like the distractions while the vehicle that could make all the side trips easier is F.O.R.D.
This is the driver side of a bare block. The red circles are the oil galley plugs. The flat flange between the second and third is the rear oil cooler head mount. The two downward cylinders on either side of the first (from left) red circle are the lower engine mount bolt bosses. You can see the top mount threaded hole above the first circled one. You will not be able to use this port because of the mount. The second (middle) one is really tight to the oil cooler. That is where I threaded my remote pressure sensor into. The 3rd (right) port is right next to where the exhaust comes down. This is the common location for some oil feeds.
If I'm not mistaken, you would have to have a 41" line to reach the oil feed on the turbo from the block mains ports. The rear block feed is a 24 inch line. I chose the shorter route. I don't know if it makes a difference with the mains feed oil line running so close to the exhaust, but pushing 1000 degrees egt towing, I'd personally not chance the heat resistant characteristics of a made in China oil feed line, even with a fiberglass sleeve. The rear block feed is also close to the turbo also. Mine is fiberglass sleeved. In the event of a failure the OEM sensor on the turbo would read zero. The remote one coming from the man's oil port with still read. In the event of something catastrophic happening, like a failed oil line, I'd rather replace a turbo than the crank/bearings and everything past that point. I don't know if this is correct, but I also do know that it isn't. The two sensors (OEM and aftermarket) give me peace of mind. Ford is known for doing some wonky things, like the crushed downpipe, but I doubt they would choose a bad location for the NA sensor and the turbo oil feed when it comes to pressure.
