What is your EA82T doing?
That Conditioner was made for one specific application - Phase II EJ25 external coolant leaks (2000+ EJ25's and 99 Forester and Impreza RS). It doesn't work on Phase I EJ25's at all. Unlikely to help an EA engine.
If your EA82T has an external coolant leak similar to EJ25's then maybe it's worth a shot. But they usually blow much worse than that and I've only ever seen one externally leaking older generation headgasket. May be risky considering the cooling systems differ.
If "repairs in a bottle" work, it's usually a limited time frame - which often means more overheating episodes which do bad things to the lower end block which won't be repairable..well not without massive expense. Blue Devil gets touted a lot for folks wanting quick fixes, but I don't recommend it.
