This is the first sample from my son's Odyssey with 150k miles on it. He's had the vehicle for the last 50k. I'd been hearing what I thought might be the start of a rod knock so I wanted to see if anything was showing up in an oil analysis. Happily, seems to look just fine, don't you think? I suspect the noise I've been hearing might just be a valve set too loose. We had the valves adjusted when we had the timing belt changed at 100k. He changes the oil whenever the OLM goes off, usually a bit longer than this but they do a fair amount of short tripping to the kids schools, etc. This engine does NOT have the VCM option so that's a plus I think...
