Rod Bearing poop? Question

[74desertduster]

So I am assembling the 360 I purchased from a guy who got it from an engine house. He had it partly torn down so I am checking it over as I assemble it.

When I got to the last rod bearing...I found this bronze looking blob on the surface of the bearing. It is raised a bit cuz I can feel it. I checked the crank journal and it is clean.

I haven't done any bearing work in 25 years.....so obviously I am like a newbie all over again.

This just did not seem right to me....thoughts?

Thanks!

Not good at all. Looks like the top layer has flaked off. Sorta like a pot hole.
I would suspect the whole set. Don't use them (bearings are cheaper than a motor) as you might end up with this....

yeah your down to the copper layer. a new set is fairly cheap and i wouln't chance damaging anything else.

Whatever it was...it was raised...was able to polish it off with some 2000 grit sand paper...but that bearing is not gonna be used....sucks cuz it was brand new like that...

another example of the quality, or lack of, that comes from aftermarket today. We have to inspect every little piece. Be glad you found that flaw now and not later.

For sure...you know what is a drag too is that the engine shop that originally built it missed it....
