I've done both. Still get condensation...

I use to think the same thing, a lot of heat there on a cold trunk lid, it was my denial. I replaced my expansion tank (Cracked with trunk filled), new cap still had condensation. I was having to add a 1/2 cup top off every couple of months. Then I started to see a couple drops on the garage floor. The condensation was cooling and draining out.
I sandwiched bagged the purge valve, cap and top of tank and low and behold the purge valve was leaking pressure out of the 'O' rings. Replaced them and now no condensation, no topping off. Condensation is an indication you are losing pressure from something on the top of the expansion tank. BUT it's not going to result in a 1-1/2 gal. leak
