i remember someone using vinegar to fill the engine, warmed it up and then flushed several times the engine with water before using antifreeze.

I am sure someone will back me up.

You can just flush it through with a hose, using a small wire brush to get at what you can reach.

Citric acid is the Daddy for cleaning rusty metal. I cleaned a bike petrol tank that came off the Titanic with Citric acid, and couldn`t believe how shiney and new it came out.

Bought the acid off fleabay for a few pence and filled tank with water, added acid, left a couple o days then flushed. "Awesome"!!! was the only word i could use at the time.

Do you know anybody that works in food production factory who can get it???
