Thermostat gasket leaking AGAIN!!!!

i guess i am still puzzled as to why it is leaking. it seems to be the gasket coming apart at the factory sticky surface, are all gaskets that was now?

if i used that Permatex that @Icetech says will i still need a gasket? i assume yes, so if i get the same type of gasket then how does that solve that issue of the gasket failure? i believe this to be the failure point as the first time i remove the housing the Permatex i used was very well stuck to all parts of the housing and the intake. the clear film, that used to be sticky was on one side and gasket was on other. i have not remove this time to see where the failure is. got frustrated as i was working on a fueling issue and seen this leak AGAIN!!!
