hey guys i've only had this prelude for about six months and i love it to death. I figured since it had 190,xxx miles on it i should make it a habit to change my oil regularly. I did so, but on my way to work i all of a sudden heard the the notorious "knocking" in my block. My question is if i drove the car for about 10 minutes while i heard the knocking would it have positively damaged my crankshaft? Do i, or should i get all new bearings, or can i just squeeze by with with one? HALP.
