Re: 70 C-20 4x4 Suburban Father/Son project

So I had some time over the last few days to start tearing down the donor rig...
And thanks once again to Nick my new diesel guru for tips on extra stuff to get from the donor!

This is what I started with. Lots more rust than I first thought which has made the tear down process harder as things don't want to come apart. We are so spoiled here in the desert to be pretty much rust free. Not sure where this rig spent most of it's life?


I am so not happy with the way the previous folks did the hose work. All I can think of is to print this pic and tape it to the 70 burb with a note "Don't do this!"


The old radiator tells a real horror story...clearly it was a leaker, and the oil coil or lines or something was also letting a bit go. It does have metal tanks which I like. I plan to take it by my fav rad shop and talk to them about repair vs replacement, I just don't want plastic tanks.
I am also debating getting the trannie & oil coolers out of the rad...thoughts? I don't do much cold weather stuff (hate the cold) so not too worried about that.


I was finally happy to get to this point which is much closer to pulling the engine. Don't worry I was taking plenty more pics of how all the tubing & wiring went.


A better view of the turbo setup. Nick thinks it is a Banks & ATS combo hack job. Maybe put together with craigs & fleabay parts?


This crossover pipe will be done differently no matter what it takes. I can't stand the way it runs along the oil pan, way too close to the belts and looks like it must cook the harmonic balancer.


Always fun to find cooked wires that the previous owner just did hack jobs to get around.


But on a note of joy I will say that having a wife who is an office manager of a diesel machine shop is nice when you need a part cleaned. This is the junkyard J code manifold that is ready for install.


Oh joy, power door locks will be in my future. I like the looks of the old iron but some modern stuff is nice


The previous owner already hacked past the glow plug controller, which is fine by me as I plan a full manual setup anyway. I would rather a stealthy glow button as a theft prevention measure.


And there are still a few bits I want like the 40gal tank & skid plate. I also got the rear aux heater, rear AC, receiver hitch, a bunch of wire, connectors and I need to try to get out the front shoulder belts since they are blue!


Monday should be "pull the engine day" and then I can get the donor carcus out of the way and pour some concrete for a new workshop to be ready for the transplant surgery.

My plan with the engine/trans/tcase goes like this:
Take heads & block to my wifes shop, have them look for cracks and tell me if it all is any good.
If all is well then I will ring/bearing/gasket it and reassemble.

Take the turbo to a company we know very well and have them check it out.

Take the IP in for a rebuild with top parts so I can run junk fuel in Baja and maybe some bio. New injectors of course.

Take the trans into a shop for a look over and make sure it is ready to continue life behind a oil burner

Combine my tcase with a Dodge one off of craigs to get one that has fixed yokes.
Check into the clocking rig and see if I can make that work.

Any and all thoughts welcome!
