Depending on the damage already done changing won't matter. It might last one mile, it might last 100 miles. The only real way to fix this is by pulling the motor and doing a complete rebuild pretty much. You've got metal shavings all over the place in your oiling system now, other bearings were probably harmed as well, that rod is screwed and out of round, the cranks rod journal is scratched up/out of round now and will require replacement (or turning if we can turn out cranks?), after trying to do what you are going to do on my DSM TWICE many moons ago it always resulted in failure very quickly, much disappointment and tons of money wasted.
