I bought two of these for my two Miats over a year ago. Both flowed all the time. I reinstalled them and after a few days they are still leaking. I finally gave in and bought two original pads. They've been in the car for a month now, dry to the bone. Some people may have had better luck, but for an extra $20 an OEM gasket will seal a lot better. This isn't just my experience. Many people on Miata.net are reporting the same issue with aftermarket valve cover gaskets. This is one of those parts that you only have to use with the OEM.
