The water jacket area looks to be in great shape.
Thanks for keeping us updated.
Bill,
How did you clean your block. It looks almost like the old “Hot Tank”” acid dip.

I believe that the machine shop has a fairly high temperature oven that they use for cleaning castings. I don’t know the details of just what it is but I know that they got rid of their hot tank a LONG time ago.

Most modern shops steam clean the parts with soap and water in a sealed high pressure washer that looks a lot like a modern dishwasher with an oil and dirt separator. Then the parts go into a oven at four hundred degrees for about ten hours to bun off all residue and turn everything to ash, then they just blow off the parts with air. Works good. And no hazardous waste.
