Speaking of working on your own truck, Im gonna change my turbo, need help

I have a 12.7 and im gonna be changing my own turbo. I do a lot of stuff on my own. Never have done anything like this. I believe I have the tools, ive watched videos and have gained massive confidence in myself doing this job....

Ill post pre/post work. From everything ive seen. its more or less, remove and replace. No need to disconnect the batteries, etc. Im typing this after I sprayed a few bolts with PB Blaster. Giving it a few to soak in. Ive taken the week off...... Im hoping of course it only takes a few hours but, I dont want to rush doing it while under a load or rushing to do this needing to pick up a load.

Any words of advice? Or anything I should know or maybe ive missed??

FYI…. Fixing leak around the water pump will be next weekend

 

Ok on replacing the nuts/studs in the manifold.

The Return line...The line from the turbo to the oil pan correct? Ive got the gaskets and all of that came with the turbo........ do I need to use any kind of gasket maker/liquid on the gasket itself?

Its actually going pretty good so far...both oil lines came loose easily. The top 2 nuts on the manifold came loose easy.......aI didnt have to fight with any of the clamps. Unless im missing something, only 2 left are the bottom 2 on the manifold.

Can you explain Pre-lubing the turbo?

 

Nowhere near as bad as I thought it was going to be. I thought everything was gonna be seized up!!

 

I’m assuming I’ll need an o-ring right here as my new turbo doesn’t have 1

 

Also, I have 2 gaskets here. I know 1 is for the bottom of the turbo for the oil return line. Where does that smaller one belong?
