looking at cars right now and one car has a spun bearing damage....
how much does this cost to repair and should i even get the car with that damage?
Pretty involved process, the engine will have to be removed from the vehicle and the a good portion of the engine will have to be disassembled. And after all that replacing one bearing (be it a crank or rod bearing) it is best to replace all of them for continuity... I would keep on looking.
I highly doubt it would be worth this trouble. What kind of car is it?
Two things to consider with this car...
1. You are a mechanic and can save a ot of money buying a car that needs amjor work, or....
2. The car is worth far more then you can buy it for, and it's worth paying in excess of several thousand dollars to have the engine replaced...
Depending on the vehicle, it will cost a minimum of $2k, and perhaps as much as $5k, to have the engine replaced. Are you getting the car cheap enough to warrant paying that kind of money to have it repaired....
I suggest you continue to look, and get knowledgable help to make your selection...
thanks guys, it was an integra gsr converted into a type r.
i dont think its worth going through all that right now, but thanks to u guys i can make that decision.
KUDOS!
If a bearing is spun, the crankshaft and the connecting rod on that cylinder are both junk.
If it's a b18c5 you're speaking of, you could just find another GS-R crank and a set of rod and main bearings. Both the GS-R and Type R engines use the same crankshaft. (just different pistons and rods) I reccomend ACL bearings for a Honda engine. They work quite well for all the SCCA race engines i've built, and you don't have to go through the factory complicated process of select fitting the bottom end.
I bet you could put a used crank and new bearings in that engine for under $500, if you're doing it yourself.
PLEASE trust me when I tell you this. DO NOT ever try to reuse a connecting rod that has had a bearing spun inside of it. It is worn dowon so much inside the bearing bore that it will no longer hold even a new bearing set. It will just spin again. The only exception would be if you took it to machine shop and had the crank end re-sized. (mostly just a waste of time, cause for the machine labor, you could just buy a new rod)
I tried to replace just the 2 spun rod bearings once in a Saturn I got for $100. Because I was lazy and wanted to just remove the pan, slap in the bearings and go, I screwed myself.
It lasted about 30 minutes before it spun them again. Not to mention that the rod journals ate the surface right off the bearings too. I thought I could get away with cleaning them up with emery cloth. NOT!
A spun bearing isn't THAT bad, you just need to replace the crank, bearings and the affected connecting rod. Most of the time, if it was still running, that means the top end is still ok, and you can re-use the pistons/rings.

It depends on the mileage of the engine, but yes, I have done that. it worked just fine.
Hmmm... Well, I suppose it's partially because you're a mechanic yourself, right?
I guess if I were to go to that much work, I'd be inclined to just go one step further and replace everything.
Did you have all the journals of the crank ground, or just the ones where the bearings spun?
