Another Blackstone report looking for input.

So this is the first report for this car. The reason I went through with it was the fact it was at a shop getting work done and a re tune. They came back to me with a missfre issue and telling me my oil was full of metal. This sample was pulled from oil with unknown mileage. I guessed at 1,000miles. I’ll attach a picture of the oil drained from the filter, I ran the all oil out of the pan directly through a coffee filter and found 4-6 tiny specs of metal. Also I should say that the oil from the pan looked nothing like the oil in the filter. Guess I’m just looking for some input from people with more experience in these situations. Does anyone have a diagram how the oil flows through the block?

I mean I wouldn’t feel great about that much glitter in my oil so I’m kind of surprised blackstone says it’s all good. I’m sure guys with more experience will chime in but my first thought is I’d be concerned about bearings.

Did the shop use a clean drain pan?

That I don’t know. The bucket in the picture was from my garage and it was not clean but that glittery oil was directly from the filter.

Looks like the filter did its job.

Well that’s more clear. I was questioning the oil perhaps being contaminated externally.

The oil does indeed look kind of scary. The chemical analysis doesn't seem to match. I think this is an artifact of the method they use to test samples, "Inductively Coupled Plasma Mass Spectrometry" (ICP-MS). Basically, they use a super-heated plasma (much hotter than a chemical fire could generate) to atomize a sample, and then they analyze that gas. At least with the ICP I'm familiar with, the sample has to be injected as a mist. So the sample has to be filtered for particulate before going in to the machine. So they'll detect truly "dissolved" metals (nano sized particles) but not big chunks. A bearing that wears out and fails will produce lots of nano particulate on the way to wearing out, that would be seen in an analysis like ICP. But if a bearing suddenly started to disintegrate, breaking up in to visible-to-the-eye sized pieces, ICP might not be capable of seeing that contamination.

It doesn't look like Blackstone does a "particle count" analysis, which I'd argue they really should since that would capture both the quantities and sizes of any particulate suspended in the oil but too large to get through the ICP's sample filter.

The oil you are using needs more Zinc & Phosphorus to protect the Crankshaft and camshaft.

I have maintained regular reports. Based on the image you posted, a report would reflect high metal ppm. The report you posted does not match the image sample.

That was a ton of help! I greatly appreciate that input.

What part of the report would reflect that? Insolubles?

The visual doesn't appear to match the report.

That oil definitely does not look good.. 50k LSA typically is a fairly safe bet especially considering its stockish or at least it sounds like it. I’d do a full bottom end inspection on er. Good luck 🙏🏼
