ditto...
when we pulled my friends engine (160K) out, he had a small knock that we correctly diagnosed as rod knock...his bearings were about half gone, nothin but copper on the #4, and #5 main bearings, and #4 and #8 rod bearings...they were gouged all to hell and the journals themselves looked pretty terrible too. The knock wasn't really all that bad either, you could hear it as it passed between 2k-3k rpm, and the only thing that kept it quieted down was 50wt oil...and he was really easy on it till we pulled it about two months later
but yeah, if you hear a rod knock, it's time to start searching out options for an engine swap, or at least a shortblock
sorry dude,
you can always salvage the bottom end by getting the crank ground, rods resized and everything cleaned and balanced and drop it back in the cleaned block with new bearings and rings...
i dunno how much machining goes for in your neck of the woods, but here, the shop i take my engine parts to will ball hone the block, clean it, put in new cam brgs and freeze plugs, grind the crank, intall new rod bolts, resize the rods and clean and balance the whole assy for about $800...and provided the assy is correctly installed, all will be fine
