i would not suggest it nowadays.. but in the 60's during my used car lot days it was a common practice to file a rod cap some to clear up a rod knock.. but that was just a quick fix which was a toss up on how long it would last
Long enough for the check to clear so you can buy some new huge bell bottom wildly colored corduroy pants, a shirt with a giant collar, and a tacky sport suit jacket with the fake leather elbow pads. How big was your hair?
