You must have misunderstood as well about changing the oil, we thought that the man who we bought it off may have been wrong about the head gasket as h isnt that good with cars

The reason we changed the oil was the car had been sitting a while,probably about 6 months and when we checked the oil it was a nasty pale brown color and even us banger boys no that thats **** oil
