I have done a bunch of high temp cooks since I fried my gasket and replaced it back in November.
I have noticed on my latest all nighter that every time the stoker kicks on I'm losing some heat and smoke around the gasket. It isn't melted but pizza's sure do do a number on it after a while.
I haven't noticed the leak but since there are 5 wires running between the dome and base there is not enough soft gasket left to seal around them.
Oh well, now I have a excuse to get the High temp one from the mothership.
