A block full of rust
Removing rust from the block, lapping the valves, flushing the radiator
I noticed the car was running a little hot while driving around town during our local "Old Timer's Day". I decided to pull the head and check the block. It had a lot of rust in it causing poor water circulation. The head itself was clear, but the block passages had a lot of rust. I was told that vinegar could be used as a rust remover. So, I poured white vinegar into the block and let it set for a few days, then flushed it with water. Worked rather well.
I decided to lap the valves while I was into it. A couple of them looked as if they might be leaking some.
I read on the Model T Ford Club International's website (MTFCI) that toilet boil cleaner was sometimes used to clean radiators. I laid the radiator flat and poured in the cleaner, then added hot water and let it set for the afternoon. It did a good job.
