when i interned at town BMW/Mazda this black guy came in with his miata with a bad motor… well the reason the motor was bad was he took off the “710” cap thinking it was for the radiator and stuck the hose in it and filled it to the top then started driving. I still remeber the tech talking to him
tech “so you put water where?”
dumb guy points to the oil cap “right there”
tech “so how much did u put in?”
dumb guy “well i stuck the hose in and filled her up”
