Hey fellows, I was trying to change the motor oil today but I couldn’t unscrew the drain bolt. It easily screws in both directions, I spend like an hour trying to unscrew it, then another hour trying to tighten it back but it just rotates freely in the same position. I’m afraid I’m going to loose all my oil since I couldn’t tighten the drain bolt !!! I have no idea that to do… any good advises? Please help!
