Engine noise- stuck lifter?

Cut the filter open today. This is what I found. Some small silver particles. No gold ones like were in the oil drain pan.

Results are back from the blackstone oil analysis. They didn?t seem too concerned. It doesn?t seem like the bearings are wearing, but there is a lot of iron and aluminum. Could one of the lifters collapsing, which may have caused the an engine noise, resulted in a cam lobe or lifter itself getting beat up?

? Using a fuel additive before sampling can result in a low flashpoint, but not in this case. No
water showed up either. Aluminum (pistons), iron and nickel (steel parts) are high compared to averages,
which are based on a 2,400-mile run. Copper looks fine on a microscopic level, but if you find more visible
metal next time then there might be an issue with brass/bronze parts - let us know if you find more metal
next time. The slightly low viscosity isn't a concern. Check back in 1,000 miles to see how metals are
trending?
