Suspect blown head gasket (or blown turbo seals?), video of the problem from before it starts, to it being bad Options

How ironic, after commenting on 2 overheating threads, my engine also overheated. - when this happened, i was missing 3 litres of coolant from the radiator it was completely empty even though i top it up once a week

I flushed the heater core, flushed the system, installed TRD thermostat, poured in 4 bottles of Toyota LL coolant, idled up to temperature, installed TRD radiator cap, rolled down the driveway facing up, ran the engine at 2000 rpm with the radiator cap off and funnel inserted, topped up as necessary and refit TRD cap when bubbles stopped coming up.

Procedure took several hours to complete, afterward I took the car for a hard blast, everything seemed okay and the heater was now giving beautiful heat, however when I got the car back in the driveway I had white smoke start billowing out of the tail pipe.

I re-checked the coolant and its still good, and the oil isnt sludgy so I can rule out the head gasket, I fear coolant is getting into the engine and burning out the exhaust but how??? Where do I go from here?

You said black/blue smoke while reving? Had the same with my old 2nd gen 3s-gte, and it turned out to be a faulty headgasket.
This is what it look like when I took the engine apart:







It started with a little more oil consumption then normal. That was when the black/blue smoke appeared. Later on, engine started overheating and smoke became white when cold. That also was the moment the coolant start to disappear.
Before taking the engine apart, I thought it was the turbo that caused the problem because of the black smoke at WOT. It turned out the turbo was just doing fine.

The engine itself was running perfectly normal, no powerloss or stuff like that.

Short story: my bet, despite the compression test you'd perform, is on the HG
