Feel for you Don - hate being in the middle of something saying to myself, HOW could I have been so dumb to think that this was a good idea?  Prayers sent your way!
Ah, thanks Mike...But I'll survive, and someday soon, have a pretty strong and well built D-Max truck

It needed that pump in my view anyway, so I guess this is just the level of sacrifice it requires. I will get five or more years out of it of primary use!

That would have been the worst part

No work on it today

Pushed the knee too far last two days, taking the day off.

Called to order a new Pro-Fab passenger manifold, however, just found out they now have a new (different) design. Waiting on a call back. It will be next week sometime when I drive again...

OK, so I just spoke with the folks at Pro-Fab about the snapped off bolt in my manifold

Rick has changed the design of the manifolds, so if I ordered a new driver's side manifold, I'd have to either send him my up-pipe to get modified, or buy a new up-pipe, and then I'd essentially own some hybrid set that would be hard to service in the future, and I just demonstrated that service is indeed a possibility in my future.

So I just ordered a new set of manifolds and up-pipes. THey should be in the mail early next week, so true to my word, it is going to be two full weeks to get this job done!

That hurt the pocketbook, but Rick did offer to buy back my old manifolds and up-pipes. He could refurbish and resale, and offered me a fair price for mine, so all in all, I do not consider this to be such a bad deal. In the end I'll be out some $500 more ish, but that's life when you get to messing with these very expensive diesel trucks.

In the mean time, I'll get the rest of the job done and prepped for final reasembly.

I think that they are referring to stainless nuts/bolts or stainless that has threads cut into it. Install the new system using non-stainless hardware and you’re GTG!

The biggest problem imo is the grade of the stainless. Hardware store stainless is way to soft (similar to grade 2-3). I think ARP carries the good stuff (like 17-8 iirc), but still degrades with heat (loses rigidity, stretches),  isn't as flexible, and all of them are capable of gauling.
...and use copper anti-seize for high heat. The silver works, but not as well.

Copy on the stainless thing
FYI, all the fasteners were coated with copper anti seize when assembled. Apparently the galling still took place. Almost every fastener had some galling on extraction. THe one bad one resisted the many spray-downs with the penetrating oil I use on stainless hardware and snapped off.

So now that I purchased a whole new cast manifold and up set, the 2" or are they 2 1/8"...?? Anyway, the first thing I did today was to pull off the remaining up-pipe

BTW, if anyone wants to purchase the manifolds and up-pipes, you can have them for $400. That is what I was offered by Rick to ship them back. You would have to extract the broken off bolt, but other than that, they look to be in good condition.

I'm getting serious with getting clearance to move around. The bolt below the second from the rear cylinder was directly behind the shock tower, so I drilled a 2" hole in to to get better access. Even with the hole it was tricky getting that bolt out

Once you loosen the big nut securing the gear onto the collet, it is swapped over to the CP3 after installing the adapter plate onto the new CP3 pump

I used a lot of engine assembly lube when putting this thing back together.

The hole where the pump fits was liberally coated as you only get to use hand pressure to slide the new pump home. It is a hernia maker, but eventually yields.

You have to install the proper barbed fittings onto the new pump, but in a jiffy-quick, it is ready to reinstall

It felt good to start reversing this massive teardown and start heading back the other direction!

The main fuel lines went back into the valley with the pictured shorter 90 degree piece replacing all that other business.

That is installed with the line resting in the valley and is hard to get to. Further it has a 24mm nut and another that is 7/8"
Those are big wrenches and the space is limited

And that right there pretty much completes the installation of the CP3

Now it's onto prepping all I can for the turbo install, and swap out the water pumps and thermostats.

After that I can partially reassemble the front of the motor!

Is the new turbo a VV also?

I think the hood will lock straight up for service. Remove the front bolt on hood and rotate up, then put a bolt back in.

No not a VV

Not water cooled

does not mount up all the LML electronic bull crap. I had the software guys write out those lines of code in my new tune. This setup really simplifies the complexity of this otherwise great motor!
