When i was training to be a mechanic, i was training with a real odd bloke who ran his XUD 305 derv with no oil, he caused us all nothing but problems, it was knocking so i said "Oh its just your tappets, rev the tits off it until it stops" so he did and sure enough it threw a rod! i said it will miss for a few miles, so drive it home and it will clear up, the dosy git drove 8 miles home and made it too! trail of oil behind him.

This is going back a few years by the way, i would never so such a thing now
