Put it in the freezer for 15-20 minutes. Be careful about putting grease or too much of anything on the O-ring to hold it in place. This is the major cause of causing the derby cover to warp as you're tightening it if you've got a lot on there.
The plain O-ring was used on Evo's. The newer style, more like a quad seal, with small nubs on it was made for both Evo's and TC's. The one for Evo's was marked with a white dot on it. One for TC's did NOT have a white dot on it.
I yam what I yam.
