I’m “hoping” to find at least 1 bearing.

If I can, my thoughts are grind the OD of the shell to the proper interference fit. Using proper tool post grinding process of course.

It will only require ~.0025 off the thickness of the shell.

Then, will need to check alignment.

Not gonna be easy, but I have to do it to save the block.

Next step will be a custom bearing shell. Then have it Babbitted.

Here’s an interesting read from Mahle. Last paragraph.

We've pinned loose fitting cam bearings with a roll pin installed through the valley pan bolt hole.


The hole that is .005 too big, is there any press fit with a new bearing?

mgarblik,

Depending on price point, I may buy more to make it happen.

Shiny,

Agree, they wouldn’t have stopped, track in the block, reset the dimensions for the cutter, then took it back apart on the line.

You could see the original machining marks on the bore, and they looked exactly the same on #4. There the engine had never been apart so my only speculation is it was repaired during assembly not block machining.

Be curious if anyone on this site work at the engine plant?
