Stopped at the parts store that I got the first stat from to get another one. I figured what the heck, third time's the charm right? I inspected it before I bought it, and it had a nick out of it and didn't seal at all around the whole ring. The other 5 (All Stant) they had in stock were all the same. I passed and went to a Parts Master store and looked at theirs which is a MotoRad, and it sealed perfectly around the whole ring. I'll install it in the morning and see what happens.
