I think when the engine was built 5 yrs/25000 mile ago, They just didn't flush out the block and heads well enough after the hot tank. The stuff in there is little pieces of rust/scale, possibly casting flash that's flaked off. Yes, I run plenty of coolant and change that every year. Is it possible to remove/install freeze plugs with the engine in the car? I've seen advertised a cooling system filter that splices into the upper radiator hose. Looks like a big in-line fuel filter. Anyone ever used these? Right now my radiator seems to be acting as a filter. Hopefully this radiator job will be the last for a while.
