Just a comment here.... and I may have mentioned it before, but consider this. When I was working field service, one of my customers was Armstrong World Industries. One of their departments made gaskets for OEM's. They had a nice little building out back with an engine dyno. They were doing gaskets for Cummins at the time, but did most of the gaskets for many other builders. I got to be friends with the tech in there, as I was servicing PC's that were doing data collection on the engines they had running. One of the things he told me was that when they did a gasket for an engine, the customer would provide the engine and the specs. They would design and build the gasket, then put it in the motor and run the motor at its rated full horsepower and RPM until something gave out. He said by the time the gasket design was finalized for the given builder, the gasket was not the failure poiint anymore. I'm trying to envision in my mind how other companies that make gaskets go about testing them. Here you have a company, spending all this money with Armstrong, to build the best possible gasket for that particular engine, and they devote hundreds of hours to testing it. Then you have other companies that don't make engines, but just gaskets. I wonder how they can purport to be as good given the fact that they cannot possibly test hundreds of gaskets like that.
