Spun rod bearing...anyone ever put new bearings in under the car?

[KevinB]

Last night at the track, I spun #4. This was only the engine's second run down the track. It was sitting for over 6 years or so.

Anyways, I dropped the pan just now. Rod #4 suffered a spun bearing. The crank doesn't look too bad, but not good either. The ridges aren't too deep. I'm thinking of some fine sandpaper and another bearing I probally wil not race the car again until the new motor gets done, but I at least want to drive it still.

Anybody ever have any luck doing this? If so, what did you do?

TIA

i did that to a buddys supercharged riviera. i even went with .020 on one rod and .010 on another rod....it lasted 3 days. so i wouldnt chance it. you will need a crank if you want it to last....just my opinion though

Your rod is going to need to be resized as well.

I do have some other piston and rods from another motor. I could pull the head and drop in a new piston/rod combo.

Kevin, hate to say it but that is a waste of time and money.

Pretty much sums it up right there.

Pull it.

if the bearing spun it is dead. If the bearing just got slightly worn but did not spin - gamble, big gamble. however since you have some ridges - it sounds dead.

Did that to my GN.

Lasted 1.5 miles. Just long enough to fill up with 93 and limp back home. I pulled the engine and rebuilt the bottom end + timing chain.
