1st test run: Bad exuahst leak. Turbo to up-pipe flange. The tolerances are so tight, the turbo clamp can't be relied upon to cinch it all together.
Those kc turbos nerds only show one method with everything out of the truck. It didn't work:
I walked away from the vehicle when I thought of lighting it up with a 12 gauge.
After rest, an idea came to me:
Get a camera back there and see where the misalignment is, with the turbo clamp removed. It was maybe at most, a 1/8" misalignment at the bottom.
Nobody has mentioned this anywhere, but what I ended up doing was fishing a ratchet strap back there around the back side of the up-pipe flange. Hooked one end to the rear engine hoist eye, the other end to the front tow hook. As I cinched er down, I tapped on the up-pipe flange with a 4ft breaker bar. She went home!
To work on everything was aweful mechanic yoga:
Place tools on woodstove to get them warm to the touch. Race outside and have at er before those tools go back to single digit temps.
Jam forearm between turbo and firewall till your bleeding. Rest forehead on lip of firewall. Laying completely over top of engine, rest sternum over top of alternator.
Bolted the turbo clamp and then removed the ratchet strap. Massive exauhst leak gone.
