Sorry to hear that there really is a major mechanical rather than just a "tune up".
I've thought about swapping in a 4.6 and don't really think it would be that difficult. The GX460 used the 4.6 and the same transmission (the GX470 has a 6 speed) as our 5th Gen, as did the 4th Gen. It could be as simple as adapting mounts and exhaust and swapping in the ECU. All other modules possibly could stay. I may be over simplifying it, but if I had a trashed engine I would give it a go.
My son has a highly modded V8 4th Gen that gives me V8 envy.

The GX 470 came with the 4.7 v8 and the same transmission we use. The GX 460 comes with the 4.6 and the 6 speed. I'm not sure if the transfer case is the same or not.
I don't think it would be impossible but it definitely won't be cheap or easy. However, if you pull it off (v8 swap) it would be off the charts awesome.
As for the engine locking up after starting, is it for sure locked up? Did you drain the oil before starting? Almost sounds like there was some water hiding somewhere leftover.

Problem with me is I only have experience with older, simpler engines. Upon submerging, I would simply remove the spark plugs and turn the engine over a few times. If I really suspected damage, I would pull the heads, maybe the oil pan to see if there is damage. Of course there are cameras now, but before all this cool tech.
My usually occurrence of water is that the engine shut off before enough water could get in, and would just pour into the engine after it was already shut off. So no catastrophic damage was done.
I just do not see how only going to the fog lights would cause catastrophic damage, a wake from plowing into the water to me would not allow enough water into the system to cause this kind of damage.
But who knows, I am only going from my own experience, I am sure there are a thousand other examples out there. It is just that I use to play around in the water a lot along with others, and this hydrolock thing did not occur no matter how stupid we got, though never purposely trying to destroy our trucks.

I'm not sure what you mean locked up. Did it turn off or violently stop with bad noises? If the engine ran - it's probably not seized. I promise you'd know very quickly. What would really help to diagnose it would be what codes the engine is throwing.
I have a few guesses, but not enough info. My first guess is that you have an air filter full of mud. Did you check that? It's your first line of defense. The filter will saturate with water and stall the engine normally before water gets into the engine.
Also can buy a scope that plugs into your cell phone to look in the cylinders for damage for about $30 on amazon. Pull the spark plugs and take a picture of the top of each piston and post it on here if you'd like some random free internet advice.

Again, guessing here... but what I have seen happen is what I mentioned before. Most inexperienced folks first response to the engine dying in a water ingestion situation to try to start it... That is when the actual damage is done, not the initial stall (if it happened with very light throttle or idle)
The damage is usually a bent rod, but it can also hurt the bearings. So just because it turns over and starts after pulling the plugs and getting the water out.. does not mean it is good to go...

the way i see it is to attain a totaled GX whether it be 460 or 470. then take the entire powertrain; engine, trans, tcase, and all modules and harness. bolt it all in place of the stock 4runner powertrain and swap modules out then plug in and go. i know the 460 used a version of the 4th gen/ limited tcase where 2-4 was a lever in the cabin and HI-LO is actuated. i think the 470 is the same way.

Exactly. Start searching for a totaled GX with minimal front end damage. if you are planning a swap, I would check into the emissions laws for your area. Some emissions laws require the swapped engine to be the same year or newer as the engine it is replacing. Some areas don't care. IMHO, I would try to find a GX 460 just to have the 6-speed. You could be the first 5th gen to have a v8 AND a 6-speed auto.
It may be sacrilegious around here but you could always do a LS swap (GM V8). Although it may be just as much, if not more, work to get everything to work, the LS is a great little platform with tons of aftermarket support.

Definitely a possibility. I haven't had a 1GR apart, but I was kinda assuming that a bent rod would interfere with a piston wall and cause a bunch of noise. I've never bent a rod without breaking it, but I know it does happen.

Miguelon, I thank you too for doing the right thing. You are a better person that those who do not help. Leading by example is never easy, but it is a great lesson for others.
Sorry to hear your engine locked, it may have been damaged when it died. It can happen when it is restarted, but it also happens when it drowns in the first place sometimes.
In looking at you pics, the top of the fog lights are right about the top of the wheelwell. Apparently that is the max depth.
I have asked Toyota several times what the max fording depth is for the 2015 4runner and they claim not to know. At least now we know it's about the top of the wheelwell. Sorry again we learned from your trouble.

What is the latest on your engine situation?

Had to take it back in today. There was some noticeable play and jiggling in the steering wheel. ANy idea what could have caused that?

So, you didn't have to replace your engine?
Did I miss something that you posted?
Don't know, you gotta let the experts determine that !

Just guessing here along with the others but it's possible that to replace the starter they had to loosen or take apart the steering column as it goes from the firewall to the power steering pump along where the starter goes.
I hydro-locked my '95 Chevy Blazer back in '97 trying to show off and drive down in a creek rather than across it. I tried starting it after it shut off but the starter couldn't even budge the engine. The buddy i was showing off to pulled me out of the creek to the local gas station. They took out the spark plugs and ran the starter to squirt all of the water out of it. They did an oil change as well as took apart the whole air-intake box to get the water out of that too. Engine ran like normal but I had to take a few passes on the on-ramp and off-ramp of a nearby highway in order to floor it to get the water out of the catalytic converter and muffler. Eventually the brick in the catalytic converter cracked a few months later and sounded like rocks in a bucket but that seemed to be the only casualty.
I hope your situation with the engine gets resolved or we get to see your new build mod getting a V8 in there!
Nice going too with the voluntary retrieval efforts. Way to go!
