The system has been closed so don't suspect mice or other critters. When I drained it to remove the radiator the water was very rusty. With the w/p removed the block drains thru the opening created and the block drain works. As I said, I'm trying to do this w/o removing the head. I don't want to get into the valve train. It'll have to be removed to tank it. Don't want to open a can of worms unless it's necessary. DON TX [Reply]  [No Email]

I know it will make a mess and blow water and rust all over you but it doesnt sound like you have too many options left besides removing the head. [Reply]  [No Email]

There"s not a lot of skinny passages in the head that I recall so I can"t imagine it"s just rust. Maybe someone put muddy water in there in an emergency. I"d try a good radiator flush(Prestone Flush?). Any way you can hook a hose fitting to the block drain and back flush it? [Reply]  [No Email]
