I’ve just drilled and tapped my manifold for vacuum take off, which resulted in finding a fair bit of rust inside the manifold. I’ve decided to clean it with a tub of citric acid, I’ll let you know how it performs. My question is, how can I stop it happening again? I’ve seen pics of inside of blocks painted, and the runners in my heads have been painted, but it’s kind of hard to get in the manifold runners. I thought maybe dipping it in a light oil to cost the inside while it waits for fire up, my thinking being that the oils would burn off and not harm anything. Any thoughts?
Pics are of the outside of the inlet, it had some really knarly casting lumps that bugged, one thing led to another...
