I added stop leak to radiator 2 years ago. Since then I replaced radiator and the gunk has shown up in the coolant in big pools ever since. Even after 5 flushes it keeps coming back. I can’t imagine 1 bottle of stop leak could produce this much gunk. My fear is that it’s oil mixing in to coolant which would mean a blown head gasket probably & the end the line.
I am trying to confirm or rule out the worst case scenario. Thanks for your comment
