I also seem to remember reading in the manual about the system being a completely sealed system..
I "think" the phrase sealed is from the historical perpestive that automotive coolant systems prior to the 70's did NOT have recovery systems and required periodical addition of coolant. Thus marketing came up with the phrase sealed to refer to the recovery system which was relatively new at the time the Pantera was introduced.
Installing a second pressure cap on the expansion (recovery) tank might be a good thing!. The pressure that might devolp in the recovery tank would result in a greater than atmospheric pressure on the top of the swirl tank's cap pressure seal and increase its lifting pressure.
Dean, I hope you have a great weekend driving.
