Hello. A few years back my dad had taken my car to the store and didnt notice it was overheating, when he got back home I checked the temp it was at 240-250 range. Not sure for how long but I cooled it down with a scan gauge. Fast forward, I wanted to bleed the coolant before I store it for winter and this is what im getting. That dirty residue stuff is light brown when I put a napkin in the funnel.

Hello! That is definitely not what you want to see when bleeding your coolant. Based on the picture and your description, you have two major red flags here. The high-temperature event likely compromised the seals of your head gasket, allowing oil from an engine oil passage to seep into a nearby coolant passage.

 

Being the engine is trashed (not really) I guess I can give you junkyard price for it. 😮🤫🤫🤫🤫🤫
