Just Finished 3.2 l Rebuild

[tgarnoldo]

I spun a con rod bearing over Easter and I just finished rebuilding my motor. I have about 100 miles on it to date and everything runs well. I have basic mechanical experience, but I have never rebuilt any kind of engine. The key was Wayne's book and finding a good machine shop to rebuilt heads, inspect P&C's, and resize rods. The key, as noted above, is to be organized, really understand the process you are going through and be clean. As far as inspection of parts, etc. a good machine shop will should be able to inspect anything you have any questions about.


Good luck and when indoubt, ask until you get an answer that makes sense...

Hi

My 3.2 spun #2 about 3 weeks ago. What causes this?.

Typically a loss of oil pressure causes spun bearings, but it could be related to other things as well...

In my case, I found no real evidence of the cause. Another cause I have heard with 3.2 l is the rod bolts stretch and then causes the failure. I assume this is why most sources recommend ARP or Raceware rod bolt when you rebuild a 3.2 l. When you rebuild, be sure to thoroughly clean the entire oil system, coolers, lines, etc..
