Daniel,The lower crankcase has had the same treatment as the upper. It's off for clear Cerakote next week and then once it's home the arduous task of thoroughly cleaning them both will begin.
Does anybody have any tips? I'm most concerned about blocked oil passageways and imbedded material leftover from blasting.
I'm thinking numerous baths in close to boiling point water using various nylon brushes and compressed air.

You may want to check with your Cerakote person; before such coating, parts must be thoroughly degreased, including de-gasing (especially for parts soaked in oil). Depending on the surface texture, some "Cerakoters" will also vapor blast the surface before coating. So, they should return to you already cleaned outside and in.
