I just get overheat 2 weeks back . After I take car to workshop they said that I have to change water pump, thermostat and head gasket (they check head pressure and they said its fine no need to replace)
3 days after I take car from workshop I experienced overhead again up to 50% as my car is GCC spec and normally gauge is on second line from down. But this time it was little crazy
the gauge was going up and down so fast like with seconds down and again up
I send the car to workshop again and after three days they said everything is fine and no problem is there
I take car and everything was normal till 3 day
Temp gauge again goes up till 50% . I switch of the car for 2hrs and start again and drive it gauge again go’s up but this time up to 75% I just pull over but I heard something like poooof (it was like noise if water flow or steam ) after that noise gauge come down within 1 second to normal level
I drive car again (I have video below from this moment) till car stop moving  and no more starting

I open de hood and saw there is housing pipe which go from engine side to body ( sorry I don’t know what is exactly name of that pipe ) it’s totally cut/broken from middle
I take car to same workshop when they open the engine. First they mechanic guy was totally impressed for broken pipe he said to me this pipe is so heavy duty and he never saw before like this
Anyway after 2 days they said to me that cylinder block has to be changed because of damage (ref to below pics )

Since you're a 2nd gen are you still under the 6 years 70K mile powertrain warranty? Your motor's blown and needs a rebuild or replacement, good luck.
