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.

what were the conditions when it went sour?

 

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.

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

you need to have the crank turned at least...fitting new bearings wont resolve the problem...so that bottom end has to come out..with that said you have options as mentioned above.

 

+1 is it a completely stock bottom end? what rpm's? what mods? Anything else happen? (low oil, etc.?) sorry to hear about this

 

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.

 

Most cranks are surface hardened to help prevent surface wear from bearings.

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.

 

You will Need to have the rod(s) checked as well...

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

 

Come on are you serious. I have never seen my local NAPA ever regrind a crankshaft. that must be a california thing maybe but seriously, are you serious? if so I suggest you see a Counselor. no offense.

 

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.

You could do it the cheap way...

Drop oil pan, put in new bearing, trade in car immediately?

 

Yes sir, then future owner gets on evom and reads this after engine failure...

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

 

I would hate to do it the un-honest way, because I would hate to screw someone, but if you dont have the money... you dont have the money.
