Who can rebuild a banks these days, and is it even worth it to rebuild? it wouldn’t be OK to mount this turbo to my motor and run it for just a week or two?
Absolutely not. Spin balance has been compromised. Unless you want it to grenade and take out your other engine with shrapnel....

This thread will document my journey towards building an alternative fueled, boosted hauling and tow rig. Looking to build this truck to routinely pull loaded car trailers up mountain passes, occasional heavy equipment rental, and hauling trash, rocks, gravel, More IDI engines, etc.

It is my goal that in this thread you’ll find conversations on topics such as:
1. Turboing a Non turbo IDI
2. C6 auto to T19 manual conversion
3. Boosted 6.9 vs boosted 7.3 pros/cons
4. Engine building
5. Waste motor oil, WMO, alternative fuels
6. Towing, suspension
7. Timing
8. Arduino, adding electronics**
I'm looking forward to seeing what you do with the arduino. I'm planning on using one as a glow-plug controller, among others in the build for controlling boost and other shenanigans.

Both CDD and R&D can rebuild your Banks. Who knows? Maybe even Banks offers a rebuild service? If that's all the more turbo that you want, then it's worth a rebuild. If you want big numbers, then I think you may be better off selling that kit to help pay for something different.

That's hard to say, depends on the condition of the compressor housing and such. The easiest way is to get a new center housing rotating assembly(CHRA) and do the swap yourself, assuming the compressor housing isn't messed up. That's only if someone sells CHRA's for the Banks.

It doesn't take much aluminum lost on the compressor housing to consider them beyond repair by most rebuilders. I personally had as-is used turbo so trashed that Justin at R&D said he'd never felt one so bad. I got my CHRA from him and it runs well, I was able to re-use the compressor housing because there is so much oil in our intake system from blowby that it didn't scrape much even though the compressor blades were worn down from touching the housing. :eek: It was actually spinning on axis AND oscillating in a small circle. SOOOO BAD.

the oil looks good

No wonder the crank is seized.
- the 89 f350 7.3idi 500 parts truck

This is All the more reason to assume the turbo needs a rebuild before running.

Not surprising findings given the missing valley pan gasket.

The question is did the oil contamination happen before or after the truck was parked - unknown history.

I picked up a parts truck last spring with oil like that. Well it was oil after about a gallon of water drained out first. I figure that at least it's a pair of heads.

Since this parts motor doesn’t head studs, then I doubt there’s An aftermarket cam in it (russ’s logger cam, or a turbo cam) but it doesn’t hurt to look. How would I tell what kind of cam i have just by looking at it without a physical reference handy?

here’s another question, if the crankshaft won’t rotate and the torque converter won’t rotate, then how does a guy remove the TC+flywheel to get the engine mounted yp

They are good kits, just be sure to get a better cross over, and for power get a better down pipe.

Gotta love milkshakes
are they much different from the options offered through classic diesel designs? I’m interested in the differences between R&D and CDD? R&D is my number 1 pick because of performance-per-dollar-spent followed by a hypermax kit because of relatively affordability.

Edit: removed bad judgement call

I’ve thought about pulling the heads off of this motor to keep around as spares - sounds like you would do the same?

Head studs aren't required to run a bigger cam.

It's not easy. You'll have to fit whatever tool you can in the small spaces left to get to the huts on the convertor studs. Some you may be able to get with a ratchet and shallow socket. Others may take a wrench. There some wrenches available with an open end on one end and a swiveling socket on the other end. One of those might work. It may take drastic measures like cutting into the convertor and/or flexplate. Don't use a torch since the ATF is flammable.

Absolutely. I'd save everything that is still useable or may still be. That includes rods, cam, crank, rocker arms, push rods, etc. Some parts are still being made, but a lot of them aren't. I wouldn't save the oil pump, assuming that it's been submerged. The same goes for the lifters. Those are too important to take a chance on there being rust inside them that you can't see.

I know they’re like saying beetle juice in this forum, (and for good reason if they’re stealing IP) but for the academic sense I’m interested in the differences between R&D and CDD? R&D is my number 1 pick because of performance-per-dollar-spent followed by a hypermax kit because of relatively affordability.
whats this about stealing? Who is stealing what?
