This is off the subject but I used to work engines years ago that had a 2 piece like a damper behind the crank pulley or was the crank pulley that oil flowed through it and would sling the oil inside the pulley and you took it apart to clean the heavy contaminants out! I'm driving myself crazy but cant remember and Google'ing but cant find it! It could have been a stationary Engine! This isn't trivia just a question it may not even be auto related it could be industrial? I just need help because maybe I dreamed it??
LOL
Just a question to the few of you!
