More success!
Autozone has a boroscope loaner- borrow it or buy one. Absolutely want this unless you have skinny arms and smallish hands.
I reinstalled the fuel rail, injectors, and coils before this step.
I will post a video at some point but here is the summary for getting the air pipe back on the turbo.
1) The lockring will rotate from open = passenger side to closed = driver's side. There is a positive click when it is in place. Get a feel for it before trying to install the tube.
2) I think having the intake manifold out the way may be helpful. Mine was because I was replacing those gaskets too. You may be able to get around it without removal.
3) Set the boroscope on the right strut tower, roughly, facing the left side so you can see it with your head resting on the valve cover. Yep, prepare to get intimate with your engine.
4) Place several thick towels/padding on the front edge of the engine compartment, passengers side of the radiator and the leading edge of the block, about the oil filter assembly location.
5) Have a ~12mm wrench with a closed end to loop over the lever on the lock ring.
6) I ran the boroscope down the firewall side of the block close to the passenger side corner- basically straight down at the connection. Use the part as a reference before assembly to get a sense of where you will be looking/working.
7) Reconnect the sensor wire to the charge pipe before putting the pipe in place.
8) Loosely thread the mounting screw for the charge pipe- the one that goes through the wiring harness bracket. This will approximately locate the far end of the pipe at the opening on the turbo. Approximately.
9) Getting the pipe in to the housing is the first tricky part. You may be able to stand along the passenger fender and manipulate the pipe from above, getting it to seat by working the far end. I couldn't. Instead, I had to lay on the engine, right hip at about the oil filter housing, head almost touching the valve cover at cylinder 4'ish. My right arm was able to squeeze between the block and firewall, just over the transmission housing. There is a bit of an open space once you get your hand down in there, enough to move around a bit and manipulate a tool.
10) First pass- get your right hand down in there, use it to align the boroscope so that you can see the tab and the scope won't move when you take your hand away. It's a bit finicky- may want to have an external monitor set up for better picture.
11) Go back in with wrench in hand, closed end is the working end. I think I started with the loop angled down. Viewing the scope, hook the loop over the tab and start pulling towards the drivers side. With luck it will come easily. If not, try flipping the wrench and pulling again. I wasn't able to move it fro mthe starting position without the wrench, you may have better luck and may not need the wrench at all. Once you get it as far as you can with the wrench, pull your arm out, pass off the wrench and go back in to use a finger for final effort. Hopefully.
12) Mission accomplished!
13) Tighten the mounting screw and proceed with reassembly.
