HOT TANK. Hot refueling is the traditional method of cleaning dirty cast iron engine blocks, cylinder heads, etc. The hot tank is just a large metal tank that holds a very nasty corrosive hot water solution. The parts are immersed in the solution and soaked for many hours while the solution is slowly circulated around them.
The hot tank, pressure test and magnaflux test cost 105 to 130. If the net needs (boring) tweaks add 180. Blockcap costs around 180. We spent around 640 on the high end and . 575 at the low end.
I usually pay around $ 200 for drilling, break-in, refueling, decking table, freezer hoods, and cam storage. So your price looks pretty online.
A hot tank won’t really do anything against rust. If you can find a workshop that cleans cast iron with a steel oven and a fan, it will look as good as new. The acid they use to clean radiators also removes rust.

The real cleaning job
Most people consider painting an engine block when overhauling the engine. Not only does it make it more attractive, it also protects the engine from rust and corrosion. You can match your engine color to your car’s paint, which also needs protection for a custom look.
Do not use oven cleaners on painted engine parts. As the aforementioned chemist said, the highly alkaline nature of the oven cleaner removes live paint, even if you touch things for a few minutes.
