What is F.O.D? Foreign Object Damage! That is the Junk Lugnuts leave in their differentials to Shit Can Bearings! I helped this 15 year-old kid build himself a nice motor! His dad wanted to help so I told him to pull the cover on his kid's 10 bolt c-clip differential and we would flush out the housing. He removed oil as black as my tires, put the cover back on and lied to me about finding any metal shavings etc in the valley of the housing. Oh well, it's his kid to kill, not mine!
