Nope,
All that was marked (with red tape) and then sent to the blaster. He then blocked those passages with some type of metal looking "super tape" before work began (whatever that tape was, I had to peel/pry it off with a small screwdriver) I also included instructions to NOT concentrate blasting inside the cases, incidental blasting was fine. I made a small metal plate and gasket that fit over the oil pump area, so that was protected.The cases are back, and on their way to a place called Morries for machining
Vapor blasting inside the cases is a waste IMO, and can only lead to trouble. The only time I would even think about having them deliberately blast the inside was if I planned to use Glyptol. I personally am not sold on the idea, and dont use it.
