Just found out that my rod bearing for cylinder #2 is bad. I am thinking I can drop the pan and replace the bearing. Is this possible? Does anyone know a diy guide or manual for this?

thanx

Have you ever had an engine apart before? There is no "diy" for something like this. You're talking about a serious undertaking and if you've never had an engine apart before to this extent, go hire somebody.

The problem with spun rod bearings is that the "spun" material had to have gone somewhere. Most of it probably landed in your oil supply, but some of it also may have fused itself to the crank journal (no oil = hot metal). If that's the case, you have to remove the crank and have a professional do the necessary machine work.

You also need to figure out why bearing went bad in the first place. Low oil pressure? Oil pan went dry? Contamination? Throwing another bearing in there without any sort of inspection or precision measurements of the internals is just asking for more trouble.
