Pressure testing is likewise a good advice! Thanks, I'll definitely do.
For the moment I'm considering to bypass the core and fix it later that year. We have STUNNING weather and it's a shame to not run the targa ZR because of a broken heater core she definitely doesn't need...
With that I could also invest some time to go through all the pesky noises my dash produces...

Matt,
Having done this work on dredgeguy's 92, to remove and install a new heater core in one piece will require dash removal.
I think a short cut would be to cut the protruding supply and return line at the outside bulkhead for easier removal. New heater core supply and return line can be cut just enough for splicing back on after installation. This strategy might negate wholesale disassembly of the dash.
