Chrysler 3.8L crank question

3688 7
Hi, I recently bought a 2006 Grand Caravan with the 3.8L. It has a spun rod bearing. I am interested in which model year crankshafts I can replace my damaged one with. Can I replace my damaged one with say one from a 2001 3.8L. If anyone has specific experience rebuilding these engines, I would appreciate the information. Thanks.

Welcome to the forum. I recommend simply pulling the crank out, take it to a local machine shop and have the journals turned, then get matching bearings. At the same time, recommend replacing the oil pump and checking the oil pickup screen, not too many of these engines are reported as failures like this, so something must have gotten into the oil or the pump itself is not keeping proper oil pressure (hard to over-rev engines with computer controlled rev limiters and all like in the old days).

If there was .050 wear on a journal you almost couldn't drive it from the noise of the knocking rod and fear of blowing up or throwing a rod.

There is quite a bit of difference from the 3.8 having a common problem and a 3.8 having a problem from neglect and abuse, of which both of the latter are preventable, whereas, for example, a gasket leaking or a valve stem seal leaking at say 100K miles regularly is prevented through repair. 3.8s, on here anyway, has had only one other 3.8 rebuild in the past two years, based on unknown history and not running when purchased, to which a crank kit was done.

Basically, until a micrometer is placed on the journal to determine its amount of wear, an eyeball is not accurate enough to tell, but at the same time a machine shop that does do crankshaft turning should be able to get a replacement one, too.

Sorry, don't know if they changed anything that would be different over the years.
