Coolant leak problem

[Isphius]

I have an 86 1/2 supra with an 88 motor that the previous owner swapped in...it was about 90% as bad as the original motor. anyway....there is coolant leaking from behind the head somewhere. i was reading about a water pipe back there somewhere.....but i was wondering if anyone else has had this problem. so far ive ruled out...broken heater core....hoses...and the head gasket. anyone have any advice?

There is a hose back there. Probally the most pain in the @$$ hose there is too. Its cramped behind the EGR on the very back of the engine (intake side).

I have that same leak behind the back of my 87 7mgte. Heater Core is fine along with the head gasket, and radiator. Please let me know what you find out.
