When I stated " the quality of the aluminum sealing ring" I was referring to the material the washer is made of. Over the years I have seen some very soft alloys used for sealing washers on Porsches. I assume it is for cost saving or an engineering error.
That is why we only use gaskets, crush washers and seals from Wrightwood Racing. I hate oil leaks and top quality parts are the best insurance to prevent them. That and experience.
