I recently over-revved my motor (stupid money shift) during a race and am concerned about its health. Redline is 7000rpm, I'm estimating it got to ~9000rpm. This is a "stock" engine that has been re-built probably about 1000-1500 miles ago... All track miles except for ~200miles. I changed the oil, and there was metal in it but no big chunks, just small bits smaller than a grain of sand. Also pulled apart the filter, and there was a little bit in there as well. I decided to run it once more, and re-assess after that. Filled it with Rotella T and a new Napa Gold (Wix) filter. On Saturday, my friend and I put ~200 hard road course miles on it, and ~200 street miles (had to drive the race car home, cause friends car broke so it got my trailer). Burned no oil :-) and the oil looks as clean as it did when it went in, plus the little metal bits. This isn't my filter, but mine doesn't look this bad: I'll try to get pictures of my filter and oil.
