Spun rod bearing. What to do ?
Yeah bad news.. my rod bearing spun...
Is there a possibility to solve this using the same crankshaft?
Oversize bearings?
Is there anyone selling a good crank shaft/
Thanks a lot.

After the crank is turned purchase oversized bearings and begin reinstall.

I'm not where I can check this but the best I remember - the crank is surface hardened and cannot be machined. So, if that is true, then the crank is either okay or you replace it.

This does not mean you can't grind a crank down to spec.
Edit: Just in case most cranks wasn't clear pretty much any crank coming from an automotive factory today has its bearing surfaces hardened.

One a bearing goes all the other bearings (balance, main) can be bad too depending on how long it was driven, oil pressure. Oil pump, turbo and head needs to be inspected and cleaned too.
A new (or used) mitsu crank might make it easier to hit the clearance target with OEM bearings

If the damage isn't severe you can take the crankshaft to your local napa auto parts and have them turn the crank for over sized bearings, that or some other local machine shop. Prices very locally and the turning seems to take 1-2 days to fit in with the machine shop schedule FYI.

A spun bearing can cause a bent crank for sure and it would be wise to flush the turbo lines... I woul go along with at least checking the rods to be sure the big end isn't ovaled.

did you ever figure out why the thing went in the first place? Inquiring minds who own bearings want to know
