Engine Tear-down and Babbitt-prob.

Engine Tear-down and Babbitt-prob.

I lately opened the engine, which was in my car when I first bought it .

Engine still was running, but I took it off the car (years ago) as it was slow,

tired and powerless .
Engine was stored in my garage ever since and now I managed to tear it down.

Pistons look good (but will need new rings)
Cylinders look good and honing is in good shape

I found all valves and everything around completely gone.
3 valves (original–style) bent; None of them tight nor dense.
All valve-guides loose and “gone”

Funny , as engine was reworked earlier.
They used 4 different types of valve-springs (what they found in their shop, I guess)
They used hardened valve-seats ( I like this - will just have to clean that …)
They used adjustable Tappets (double-lock)

Change to new style-valves will not be a prob, i guess ( I hope)

Now my problem :
Engine was running quiet and without bearing-noises but now I found the
center main-bearing (just the lower part of the Babbitt) to be defective
(Find pics attached ).

Is that a production-problem of pouring the Babbitt or what happened here?

Please come back with suggestions how to solve that prob.
I guess you wouldn’t reuse ? ( I do not intend to reuse).
Thank you very much in advance.
