i took my engine apart to replace all gaskets and clean it, while cleaning the block i checked the coolant passages and there are deposits of some type of brown gunk that has built up around the cylinders in some places there is a pile of it that fills half the passage, it didn't have any overheating problems before taking it apart but i want to clean this stuff out, does anybody know of a wa i can clean this stuff out without having my block boiled?
