Spun Rod Bearing Question. PLEASE HELP!!

[silviakid2790]

i know this is a newb question but ive never done anything to the bottom end of a car at all. after they machine it all down how will i know what size bearings to get? and would it be cheaper to get it machined or just buy a used crank that isnt scared up?

well it depends on when the bearing spun, If at idle and and ran for a few mins then the crank migh be fine, You can probably get away with just polishing it.

hopefully its not bent if you ran it for a while, and not too fucked up seeing that your not sure when it spun

But if they have to machine the crank they will tell you how much and maybe able to tell you the appropriate bearing size. If not you'll have to plasti gauge the clearances.
Get that shit balanced while your at it too.

It will be cheaper to machine it, if you buy a used crank what not to say that one would be bent or jacked up either.

More than likely you need a new oil pump too.
