Uh....not quite. You can drop the oil pan & look in the oil pan . You might see a lot of metallic particles floating in the oil . If so , remove the rod caps ( after using a metal stamp to index them to each rod and direction) and look to see if the bearing and rod journal are o.k or not.
How much you know or don't know will depend on your success . Be honest w/yourself and Google pictures of these terms , procedures and repairs to be aware of your situation and direction you need to take .
