If you are actually going to check bearing condition, might as well slap in new bearings unless this is your only vehicle. As rod knock and pretty much all sorts of bottom end bearing wear is virtually unheard of in late B230f's unless another oil pressure problem caused the premature failure (or just that 1 in a million fluke) I would most likely just have a set of standard bearings on hand and put them in. We are talking $70 or so from Napa and they are returnable.

I know you are a knowledgeable and long time poster but are absolutely sure with is a rod knock? I only ask because it is so rare (though a few instance have been reported).
