I am just about to start thinking of getting the machining done on my six pot now I have most of the bits needed to reassemble it.
It was off the road for over 20 years and the coolant have leaked out/evaporated so the waterways inside the block are full of dried out rust, coolant flakes and salts and general muckiness.
What can I do or use to flush this all out before getting the machining done to avoid it all ending up in my nice new, and expensive, water pump?
