Did I catch This in time to just repleace bearings?

[teamitr]

To make it short some really smart person ran the car with almost no oil and when he arrived at my house I turned on the car and reved it and at 3k rpms i heard a lil knock so i immediately shut it off and droped the oil pan, removed rod caps to find this...
as you can see the really worned down one is cylinder 1. Can I just repleace bearings or do I need to get it machined? Thanks.

IN short its time for a new crank. Or atleast some machining. Just replacing the bearings wont work, Ive tried it. Sorry.

p.s. resize those pics.

You'd be better off having it turned .010 under with new correct size bearings either way. It looks like too much scoring. I mean, better safe than sorry.

You could always find a 6 bolt short block and drop it in instead of rebuilding the 7 bolt.

If it's knocking it's done for. Rebuild or replace.

All that bearing surface has gone somewhere. . . Pull her apart and rebuild it right the first time.

BTW, some say turning the crank will compromise it. But so many have gone so far on a turned stroker crank. I havn't heard anything about one failing after turning it. Or better to say, i havn't heard of one failing due to a direct relation to a turned crank journal. But, the Mitsu manual states plainly that the crank is 'not serviceable'. Research and pull your hair out .

6-bolt blocks are not unplentiful, so I wouldn't take the time in rebuilding unless you plan on getting forged internals, arp hardware, etc.
