HP turbo blew, need removal tips and advice

So today is a day, my high pressure turbo blew seals and God knows what else.
Oil in pipes and air to air intercooler (don't know what am I going to find after disassembly.
My observation and work I've done so far, removed most piping except one that feeds Hp turbo from water to air intercooler (gotta drain coolant for that first) for compressor wheel inspection if that is even in one piece(I hope it is)
Now, my questions:
1. Is there any way to clean air to air cooler without removing it (saturated with oil)
2. If water to air cooler is saturated with oil, do I have to remove it for cleaning?
3. Hp turbo is mounted to exhaust manifold 3 nuts or 2 nuts and one bolt (I don't know the combination just yet) 2 nuts on top are accessible, the 1 on the bottom is not accessible due to low pressure turbo compressor housing. Do I have to loose lp turbo housing and move it 1in or so to gain access to that Hp turbo lower manifold bolt/nut? I don't see it happening any other way.

Any tips and suggestions are welcome, if you did this job before what is the quick walk through the process of removing and installing, what other preventive things would you do while being there.
Thanks in advance, Jacob

 

So, hot side housing (turbine) can be left attached to exhaust manifold and the only thing that would be switched is a cartridge and reassembly of compressor side, that is great news then. What is the size and bolt pattern holding cartridge btw?
Do dealers sell cartridges without housings? I called them and they said they sell whole turbo unit with core exchange? That sounds like it's a reman, is that right?
Would you happen to know if there is o-ring kit available for piping only?
Also, turbo oil feeding line bottom gasket and upper o-ring are available in the kit or by themselves?
Along with all this turbo mess I will be replacing CCOS as I have it and it's right there.

 

Thanks Heavyd, very helpful indeed. Here's the aftermath
Broken shaft, piece of compressor wheel fused in the housing, turbine wheel milled down, whole lot of damage.
Question to Heavyd:
Is there any sealant required to be used on mating surfaces between hot side housing and the cup that seals exhaust gases. I had really hard time to remove that piece form housing, it had lots of rust buildup after getting it out I thought there must of been some sealant involved, I may be wrong but wanted to hear from a professional. Any tips on cartridge installation?
And how crucial is new turbo feed line as it looks like another knuckle scrapper, lol
I cleaned up piece of tubing where o-ring is located with 500 grit sandpaper, everything looks great.

Now I got turbo seal kit, it looks like it contain more o-rings (I understand it service both turbos) but still there are some pieces that are there but were not upon disassembly. For example, turbo return line had orange o-ring only where turbo seal kit has those flat paper gaskets in addition to o-rings. Do these need to be installed along with o-ring? If so, which side goes up as one side has sealant around the bore.
Based on stuff I've taken off, these are the only seals that I need replace,is this correct?
I don't know where goes 1 purple o-ring, 2 black o-rings and 2 metal rings with rubber fused into them. Would you be able to shed some light on this, thank you

Get out! 2.3 hours? I've spent 2.3 days on this thing. I'm ready to be lay to rest, my back feels like I'm 99 years old and legs like they are made of chop sticks.
I already installed an o-ring on turbo drain (I can change to paper gasket if you think it is better) and decided to give it a shot at going with old oil feed line for turbo.
Cartridge installation is something else, wow, that was a test of my will.
I've cleaned all the rust on hot side housing and used file to remove unevenness caused by rust of course. During cartridge installation I've made sure that turbine wheel is spinning freely because it wasn't at first when I was tightening up the v band clamp.
Here she is in her new home and the leftover from brand new BW TURBO.
Thank you Heavyd for your patronage, it would be a hell without your knowledge and help. You deserve tall beers from me, sir

 

A little update, I test drove the truck for approximately 25 miles and it runs good. The only difference to my old turbo is sound. New one is quite louder as it sounds like a high pitch hair blower at between 20-40 psi of boost. I'm not sure if it supposed to be like that, as I didn't have same sounding old turbocharger. I'm somewhat worried about it but truck pulls good and everything else seems to be good.
I'll see how it goes Tuesday next week when I'm back at work.
Happy Memorial day weekend everyone
