I recently pulled the injectors on my inboard diesel for cleaning and inspection. It seems pretty standard to paint the outside of an engine to prevent corrosion and the injectors/related hardware were no exception.
One thing I noticed was that some bolts/nuts on the fuel system/injectors etc were difficult to remove due to the paint on threads. Was also worried about paint chips entering the injectors/fuel lines/engine block. It also seems standard on engines to use non-corrosion resistant materials (plain steel) - in other applications galv/stainless steel hardware could be used.
Is there a way, other than painting the steel, to help with corrosion resistance? I thought maybe a type of machine oil or something on exposed threads/nuts could be appropriate but also don't want to compromise holding strength - and this doesn't seem very effective.
I am not against painting the engine and components but that seems like a long term rust prevention method rather than for something that may be altered/removed again in the near-ish term.
Cheers
