Re: Removing Rust from the Block
Man that's a lot of heavy rust. Without pulling the engine your going to have your hands full. In my opinion there's no easy short cut. The block needs to be hand scraped not an easy task in the truck especially if this is an early block meaning 24 studs holding each head in place. Another concern for anything that looks like this is the possibility of mice nesting in the valley of the block in its history. The intake manifold should be removed to check on this possibility and at the same time the amount of sludge build up in there can be determined as well. Fire engine's while never really getting a lot of driven road miles certainly have a heck of a lot more hours idling than the average engine thus creating other issues including unwanted cracks.
