2012 Acura TL-no engine compression
Was driving on interstate for about 10 minutes hot light came on next the engine died . had towed to garage they stated slow leak in throttle body caused no fluids in car that lead to engine to blow. no warning signs prior to the engine blown. thoughts on if this is unique issue . 98K miles

trying to figure out what could have happened.
The throttle body has coolant lines going to it so there's a chance the coolant could have all sprayed out that way. I feel that's unlikely since it would take quite a while for that to happen and I think you'd see a significant amount of steam while it was happening.
Did they do a compression test then? Did all the cylinders lose compression? How long was the temp light on? Tell me you didn't continue to drive until the engine died after the light already came on......

I was driving a total of 15 minutes. 8 minutes AC was warm shut it off. Temp gauge heading to Hot, then temp light came on. maybe driving for 4 minutes with light on ( on interstate trying to get to next exit. Engine died little black smoke out back never any smoke from under the hood.

or
loss of coolant somehow (maybe radiator busted? perhaps what they say is true, coolant lines disconnected ) which led to overheating issue, which then led to warped heads.
without digging into the engine, it's hard to say which happened
I'm not an expert but here are a few observations I had based on what you said in the thread.
First, it seems odd to me that the coolant could have slowly leaked out over time without you seeing the temperature gauge rise as the coolant level got lower. Have you confirmed that there's no coolant in the radiator? Is there any sign of leaking from the throttle body? If leaking was really occurring, you'd see a pretty good amount of residue near wherever it was leaking.
Second, is the engine seized or are you able to start it? If you're able to start it, I'd refill the radiator and see what happens. If your oil is milky, there's a pretty good chance that the head gasket is blown or the head is now warped allowing coolant to mix with the oil. Overheating can certainly cause that.
Last, it would definitely be helpful to get a leak down test and compression test done. That's assuming the engine isn't seized. If it's seized, you won't be able to do either since they rely on the engine cranking (compression test) or turning the crank pulley in order to get the piston at the right location so the valves are closed (leak down).
If you can start the engine, I'd fill the radiator with coolant and change the oil. With the engine cold, open the radiator cap and see if you're getting air bubbles coming out. If so, you've likely got head trouble and will likely need a head job (lol :giggity
. If it runs like crap it could be due to coolant getting into the combustion chamber. It could also be head trouble or bad compression due to damaged valves or rings, though I feel like that would be less likely.

Yes no coolant
Yes signs of leakage in at throttle body
Throttle body damaged to
Engine has zero Compression
I had Acura service open
A case and said I
Need dealer to diagnosis car before they would talk further to me
