I recently bought a 1988 Eldorado 4.5.The car has 102000 and the body is in mint condition. The water pump recently went and I replaced it. A lot of the coolant was drained and replaced. After running a few errands I checked the overflow resivoir and it was black. I stuck a screw driver to the bottom and there was a crud that looked like wet brown sugar on it when I pulled it out.
After closely examining the engine I saw that both valve covers had brand new gaskets meaning there was some kind of recent work done on the engine. My question is, is this because recent engine work was done and the cooling system was maybe never flushed could this have stirred up because of replacing the water pump? If there is an actual problem what do I need to look into intake leak, head gasket?
The car runs perfectly fine as in temperature, idling, driving, heater works. Any help is greatly appreciated.
