A woman phoned me up today and said" could you look at my car i have been told that i have a blown head gasket by a garage but i dont think so"
so she brought it down and i looked in the header tank(thats were the water is)and there was oil in the water so naturaly i thought something was wrong so i did the usualy test, but nothing showed wrong!so i looked deeper and the oil in the tank was diesel oil not petrol oil like this car was, so it turns out the garage had put oil in the tank to make out she had a problem and pay lots of money, cant believe some people are so crooked
