Take off the Coolant cover plate.
Place sandwich baggies over the purge valve and the Fill cap

You will then be able to see which one is creating condensation.
For me it was purge valve. I replaced the 2 'O' rings and cleaned up some sloppy sealant in the purge value assemble and WALA - no more condensation issues

Very Smart!
