I've purchased a couple of different sets of main bearings for my engine rebuild, 1 set of Mahle and 1 set of Silverlines.....I received both with appear to be light scuffs and surface scratches on the bearing surfaces, apparently from the way they are packaged from the factories. The vendor I bought the Silverlines from says this is common and he has used them with no issues. What's the word on this, should I be concerned about this or not? Common sense tells me the bearing surfaces should be mark free and smooth.....

I suppose it all depends on how bad the surfaces are.
Can you post a picture? Can you feel any ridges with your fingernail or are they just visual? |

Didn't feel them much or not at all? Which is it?
They get visual scratches quite easily, lightly polish them with a clean soft white cloth they should disappear. In the past I wouldn't use silverline, I might give them a second look now but I'd totally spec. them out. |

I can just barely feel the scratch visible in the photo with my nail, it looks worse in the photo than it is. I was able to polish out the scuffs I mentioned. I haven't checked the specs yet but aside from the packaging, the Silverline's look pretty good. I'll have to check how they spec out though...  |
