over on the forums there was a conversation regarding oil sampling, metallic wear and oil analysis...
seriously, say you have a large investment in a race motor ($50k+-). you wouldn't just wait till it blows up. maybe your running full systhetic oil and want to take advantage of extended drain schedule. analysis would tell you when it's time to dump it or even to just change the fillter.
here are some of the "wear metals" in a car engine that end up in the oil when wear is occuring...
Iron (Fe) Cylinder Liners, Rings, Gears, Crankshaft, Camshaft, Valve Train, Oil Pump Gear
Chrome (Cr) Rings, Liners, Exhaust Valves, Shaft Plating
Aluminum (Al) Pistons, Thrust Bearings, Turbo Bearings, Main Bearings
Nickel (Ni) Valve Plating, Steel Alloy from Crankshaft, Camshaft
Copper (Cu) Lube Coolers, Main and Rod Bearings, Bushings, Turbo Bearings
Lead (Pb) Main and Rod Bearings,
Tin (Sn) Piston Flashing, Bearing Overlay, Bronze Alloy, Babbit Metal
Silver (Ag) Wrist Pin Bushings
oh yeah, and he asked "What is the best way to tell if your engine bearings are going bad?" pending was my word.
