97 OB has bad knock

Sigh. A few months ago we got a 1997 OB (140,000)with 2.5l. It had been torn down by previous owner, who replaced one side head gasket and some other things. The other day, found a bad (probably rear main seal) oil leak and engine started knocking. Mechanic sez it's a rod, and he will replace for just over $3,000 with used engine.

Is there an alternative that makes sense? I fear the 2.5's overall history. How about if I swap a 2.2l in its place? Easy to do?

Or, should I just dump it for what I can get for car (very nice looking, all other mechanical great) and get beyond this?

Thanks, board members for helping me solve this riddle.
