So far I've taken the big 90° exhaust that connects to the flex pipe off.

Removed top banjo bolt.

Look like this...normal? Is this oil or coolant?

The back of the line was pretty loose...what does it connect to? Anyone have pics of this set up with the motor out? 2008 auto.

There was about 1/4" of play in the turbine shaft.

The plan is to swap in the cheap rock auto turbo then rebuild the OEM with better parts and see what problems the new turbo solves and go from there. (Hoping it's not the rings)

Took the flex pipe and the down pipe off. Got a better view. Can Anyone circle what else I need to remove?

Soak those bolts(nuts/studs?) to the manifold with Kroil or PBlaster. When I removed my turbo, one broke off in the manifold, so I had to also remove the manifold and take it to a welder to burn it out. It was the one that the hole didn't go all the way through the manifold, it's more prone to seizure.

Give them a liberal spray, then give each one a good tap. The vibrations help the penetrant work in.

The Haynes manual has instructions. Sounds like you have the first 3 steps done. So starting with step 4, remove the oil feed pipe and gaskets, and 5 is remove the coolant return pipe and gasket. You should be able to tell which banjo bolt you've pictured, I posted exploded diagrams in your other thread.

Step 6 is remove the cooler outlet pipe, feed pipe and gaskets. I think this is another banjo bolt setup, their wording is a little vague. They may be referring to the charge pipe and the inlet pipe that comes from the airbox, although they don't have gaskets.

Step 7 unbolt the turbo mounting fasteners (hopefully they've had a couple days to soak) and bracket, then the oil return pipe (this is on the bottom of turbo, gravity draining into the oil pan) and PCV bolt. I think this refers to the braided stainless hose that can't be removed from the valve cover.

Step 8 remove the turbo.

Do you have a link to the other thread?

I'm stuck on this bolt. 15mm is too big...14mm too small...same for the fraction wrenches....ugh. Any ideas? It's the bottom part of the turbo/flex pipe bracket.

9/16" is between 14mm and 15mm. But I would expect it to be metric

Use a 6 point socket, not a 12 point

You have that bolt loose and it’s at least an inch unscrewed. If you don’t have a wrench that fits, then use a “fit all” to finish. AKA= Crescent wrench

Threads appear to be galled. The bolt head appears to be into the part on the right, or are you talking about the 6 point bolt

It is the 6 point bolt on top. Or behind the thread sticking out in the picture. Its the top turbo weight support bracket bolt. Bottom has a nut and top has a bolt.

It's impossible to get anything else in there.
