I have a 2011 Ford Flex 3.5 limited with 204,000 miles and it started off misfiring so I changed ignition coils and then it began losing coolant than I started to hear rod knocks, checked the oil stick and there was a creamy brown color is this a blown head gasket? My dad plans on flushing all of the oil (he is a mechanic) and refill all oil. Hopefully this makes the video.
Yeah creamy brown oil isn't a good sign. If your dad is a mechanic, he should be able to handle this.
