in my 97 SS i put a used short block in it and it spun a rod in like 200 miles. it still runs though (real rough) can i just toss in new bearings and call it a day?

 

Most likely no. If it ran at all after it spun (sounds like it did) you probably have metal in every inch of that motor.

I would say at minimum you need to tear it all down, have a shop check the rods, crank, and block and put new bearings in if everything else survived.

 

normally no. You most likely damaged the crank and due to that fact you will not be able to just toss in a bearing. If by some amazing luck you didnt damage the crank you probably could. bearings spin when you have contact between the crank and bearing. If there was contact you 99.9% of the time have damaged the crank.

 

I would want all the rods checked too, and new bolts.


(This is assuming you are keeping the car, if you are shady I guess you could put one back in, see if it starts, and pawn it)

 

oh i plan on keeping the car forever, looks like im going to have to take it to the machine shop

 

i did the same thing. you definatly havet to pull the motor. no way around unless your putting one rod bearing back in which i dont recommend doing. i thought i could survive the spun bearing but the crank was damaged. so now im putting in rods, bearings, new SCAT crank, pistons and rings. best bet is to do this. make sure evrything else is still in working order though. i replaced all my valvetrain because i thought it was a lifter and ended up being a spun bearing #8 cylinder to be exact. so i have 0 miles on a rebuilt top end and now bottom end. i cant wait till its done.

 

That sucks man, I'm in the same boat as you though. Bought the car and only got 93 miles on it and the bearing spun. I was just going to put it back together basically stock, but I got too good of a deal on heads and cam and now look at my sig LOL

I have to make some phone calls, but if you took the motor out yourself you can save alot of money and have the good feeling that you did all of the work yourself. I'm going to have my stock crank turned (unless its too expensive) and get new rods and reuse the stock pistons but put new rings on them.

If you want any pointers or where to find some parts PM me and I'll try to help. I'm no expert, but I'll do my best

 

ive already taken the motor out 2 times in 2 years this is my 3rd motor i have realy realy realy bad luck.
