Re: 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.

Re: Engine noise- stuck lifter?
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? |
