Well I am just getting pieces of information at this point, but they said they believe the spark plug got too hot.
???
They are not replacing the whole engine, but going with a short block, it sounds like.
This concerns me as I’m not sure they still have a good grasp on what caused this

I wouldn’t be so concerned. We don’t have the information or technical knowledge to second guess the manufacturer. Either the short block will fix it, or it wont, either way, Toyota will take care of it. I’m pretty sure they wouldn’t go through the time and expense of a short block if they didn’t think it would set things right.
Many enthusiasts like us see something like this and want to run away because we value the “reliability” aspect of the brand. It’s more reasonable for us to understand the “sum of parts” aspect of these vehicles and their modularity which allows for sections and parts to be swapped out while maintaining the integrity of the machine.
hang in there, I truly believe they will get it right.

I had my bottom end in a 2GRFE bored out and it was fabulous on a track Lotus Evora. Precats failed, which screwed up fuel trims so bad (we think) that we got some cracked wrist pins. Nowadays, it a matter of having a shop manual and unplugging a whole bunch of connectors, pulling the motor, pulling the head....rebuild.........Remember, drag racers rebuild motors between runs.......kind of one of those watch one, do one, teach one jobs. A bit of a different skill set from boring cylinder walls, fitting oversized pistons and rings etc........
Most involved process on a short block replacement is setting engine to timing marks and heads to timing marks and assembling the two. This is done during disassembly and likely involves cam locking tools that only fit when properly timed.
Everything else is just mechanical and electrical connections.
I would hope the heads are inspected for any potential damage and oil passages are flushed along with the turbo but otherwise wouldn’t stress over short block vs. long block replacement.
I would want a full oil analysis done as well, if abnormal metals are found I’d want a new turbo at a minimum and would push for long block as well or at least add head replacement into the mix to ensure no cam bearing or lifter issues on the new setup.

My concern is not Toyota being able to assemble an engine from a short block replacement, my concern is what caused the problem in the first place and what else was possibly affected during this whole process.
Even considering all the safeties in place to prevent, contamination, it only takes one bur, chip, etc in a oil passage that finally breaks fee to cause damage. Unfortunately you were that guy. 100% perfection is not reality.
Any update on this process?

Still waiting on parts.
The block will be sent back to Toyota engineering and you may never know the root cause. It’s not in Toyotas interest to release that information. Also the dealer will not be paid to tear down the block to find the root cause. FTS will be called in and they will inspect it as well. I would ask the dealership and tech to take pictures of the bottom end and focus on the main bearings.
Also remember the lemon laws in your state and I would have Toyota extend the warranty for the vehicle past the normal time frame. Thanks for keeping us updated and there is some good information shared within this thread.

I would also report this to the NHTSA. While I am not a big fan of the government 85% of the time. The NHSTA is one of the few organizations with the power to hold Toyota accountable. You can remain anonymous and they will keep your VIN blocked out publicly. If you feel this is a safety issue and would affect someone else the reports help. This is only reason Toyota issued the V6 recall and had to publicly post the findings.
