Ever wonder why automotive engines last so much longer nowadays? I heard someone claim on a car show on the radio that the industry found it in their interest to lower the ring-to-cylinder engine tolerances and wear tolerances because of the EPA's federally mandated 8-year/80,000-miles catalytic converter warranty. The less blowby, the less cat failure within 80,000 miles.
It's highly likely that CARB (California Air Resources Board) and the EPA and European pollution control regulators weren't thinking of that positive side effect when they wrote the first pollution control regulations.
