Would you use this rod? This car will be driven a lot.

Pat
I assume the hole pictured goes through and will allow oil through?
Based on what I can see, sure I would

What begs the question, is that the ONLY hole, or is the rest of that bearing pour like swiss cheese under that lovely polished finish ? If you're sure that's the only flaw, likely there's no big problem. Any clues as to the cause of that flaw ?

It's new babbit. Had to be the pouring process.

Your bearing was a bad pour. If you find one that was cut into there is a good chance there are more. I would not put it in any engine I build.

If it was new, I would not use it.

The flange is ready to break off now!

The rod in junk, get your money back!

The hole in the top picture is from a bad pour.

Either dirt, or air bubble.

It would be hard to make a oblong hole like that with a round drill bit.

I may be mistaken but I think the two holes in the picture of Toon’s were drilled deliberately to provide oil to the top of the bearing. When this is done by Antique Engine Service, there is only one hole in the bearing going to a hole either side of the rod.
It is my understanding that the hole in the picture by Pat was caused by an air void.

That is a blow hole from a bad pour and I am not anywhere near an expert. The side looks bad and I don't speak the "language" but would call it a thrust surface (?) and it looks 80% missing.

It looks like a really bad bearing pour and not complete material. It also looks like it was finished with a wheel cylinder hone. I would not put it in a junk motor.

Listen to the experts and not me and good luck!
