I replaced both of these just two years ago and both leak when the car sits overnight in the cold (below 5F or so). That was my reason for replacing them again. Are others having leak issues?

I did use both a coating of P80 rubber mounting emulsion on the ring to get them to possibly seat better, plus a good coating of High-temp RTV silicone as well. Hopefully that does it.
