A big end or main journal bearing failure can cause catastrophic damage to the crank and/or rods. I think the oiling issues that plagued earlier 4G63 engines weren't an issue once they changed the head design, but it's still an engine. Change rings and hone the bores? - maybe. Bottom end bearings and crank inspection? - yeah, I personally would...and throw some new seals in it front and rear.
