Gary: My experience with oil analysis was all with large industrial natural gas-fueled engines and gas turbines. With periodic (monthly) oil analyses, one could watch the engine wear out and tell what part was wearing--or if the oil or filters needed changing. A single snapshot oil analysis is interesting, but not too revealing. If it has been some time and some miles since the analysis, and if you have the same oil in the crankcase, sample it again. Trends are much more viable than any spot reading. That said, the high lead and copper readings should trigger concern over bearings. It would seem a little early in the engine's life cycle--but it may have had a tough life! If examination of sludge from the bottom of the crankcase and from the removed oil filter indicates copper particles, it may be time to think about bearings.

I realize this may mean bearings, but does anyone have any experience with oil analysis and any opinions about doing the bearings?
