Blackstone oil analysts

[rjohnson_15]

Need some opinions.. I have a noise when the car warms up sounds like a bad valve or guide. I decided to do a oil analysis and the results have me thinking it’s a spun rod bearing with the high copper and iron numbers. (The high lead number is from some octanium I had in the tank)

Yeah, the copper and iron is a tad high, but I would get another analysis in about a month and compare the results. Consider that your baseline. Then get another test in about 9 months of driving. See if there is a trend of increased copper and iron over the three. If so, you might have a bearing issue. With just the one test, I wouldn't jump to any conclusions.
