New broken demon

I'm too lazy to check one of my TQ's, but I've rebuilt at least a 100 TQ's and never had a gasket problem like that. That blue colored gasket looks kinda like a Felpro Perma-Torq gasket. Is that a Teflon coated bowl gasket? If so, maybe it's too slippery. I think the bowl covers on old TQ's have a raised thread/bead on the gasket surface which bites into the gasket preventing that kind of thing.
