I am trying to revive my 86. I finally got it to a point where I can start the engine, so I went to try and flush the cooling system. Here’s the problem, I put 4 gallons of distilled water and a coolant flush bottle. Ran the engine for a few minutes ( high rpm’s maybe 1500 bc I am trying to tune my carb at the same time). Check the radiator and the water is brown overfilling out the funnel. I was an idiot and let it continue for maybe another minute. Did I blow my head gasket or is this common for an old cooling system and just had air in it?
I plan on getting a test kit.
