YES! I believe I posted it here a while back; I had gotten a super-duper rubber gasket to go between the top and bottom t-stat housing halves, and it prevented the top o-ring (Toyota parts jargon, it's actually a rectangular cross section) from preventing coolant from bypassing the t-stat. Added another on and presto-voila!
