I'm in the process of getting my valve cover and intake manifold powdercoated. The shop called me today to tell me that the inside of the valve coverhas a plastic splash shield held in by bolts which can be removed and another small panel that is riveted in. He is afraid to proceed with sandblasting it prior to coating it because the fine grains of sand may get stuck in the crevices. He also claims that because it is still in place there is probably oil still in there.
To anyone who's done this before, does the riveted plastic pieces pose any purpose or is it simple german overengineering? Is it safe to remove? Is there an alternative? I would rather not paint the pieces but am considering it as a last case scenario if so.
