If one of those pieces, as small as a pencil eraser gets in the right cylinder head capillary, you'll have a cracked head.

You must disassemble the entire cooling system and clean every part.. A flush won't cut it.

If it were mine I'd change the radiators and throw the old ones away.. Gotta take this seriously, if not you'll pay the price the hard way..
