... the water jackets in the block were full of calcified sediment that won't wash out in a flush?
I noticed the drain valve on my radiator wasn't working when I was removing it for another purpose, .... didn't think much of it.
Yesterday I opened the drain valve on the side of the block and coolant just dripped out really slow.
It's a ball valve, so it should be a wide open tube when it's open. So I shoved a nail in there. It went in about 3 inches with no resistance. Didn't get any sludge on it. But it didn't speed up the dripping of coolant.
I flushed it in 2014, didn't get much crap out of it, just a brown mixture of red and green antifreeze.
I'm thinking the bottom of the radiator might have the same stuff blocking the drain.
If that's the case, how would I verify this, and what can I do to get rid of it? Can that water jacket be accessed with the head removed?
Tomorrow I think I'll blow compressed air into that block drain while it's flushing and see if it spits out crud in the water flowing out.
