Casting Defect Sandwich Plate - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I noticed this right after I bought the vehicle when I changed my oil at 500 miles. I have changed the oil 2x since and now at 5000 miles, I have noticed it getting worse.

I don't see it causing any major issues, just kind of surprised it made it through QC.

Do you any of you have this casting defect in the oil sandwich plate?

Looks like porosity to me. You can get that with aluminum castings based on a variety of factors. While porosity can end up in a harmless location, what would worry me is if it is getting worse.

Is it REALLY getting worse, or are you imagining things? Did you measure it (believe it or not a factory would have a size spec on the porosity)? Can you confirm your theory?

Back when I worked at a factory I saw lots of parts with porosity go out the door for auto-transmissions (once confirmed to be of no concern), but I've never seen it "get worse."
