My 2003 996 C4S 65,000 Mi was just diagnosed as having a "Rod Bearing Failure", with brass filings in the oil, confirmed after "tear-down"! What actually causes this?

Typically metal in the oil causes these failures if no signs of oil starvation are present. The Porsche factory oil filter canister has a bypass valve that often gets clogged with dirt, allowing unfiltered oil to go right back in to the main and rod bearings. Upgrade your filter system, to LN Engineering spin on oil filter retrofit (which filters the bypass oil if necessary), install oil filter magnet, and magnetic drain plug. Change oil every 5K miles or annually, keep your RPM up while driving (2500+)and you must cut open the engine oil filter at every oil change to look for metal particles.
