Painting Engine side of valve lifter and rocker arm covers

FarmerHR · Dec 9, 2020

Our Ford NAA is getting a painting update to control rust, bare spots etc. When the valve lifter and rocker arm covers were remover, both showed some rust on the engine side. Was wondering if a couple coats of red oxide primer would hold up on the engine side ? Would hope this might prevent future rust or at least slow it down. Would use Rustoleum red oxide primer with no hardner.
Thank you for any help you can give me.

Regardless of what you use preparation comes first. You don't want to cover any rust because you will be enhancing its environment and growth, and no paint will stick to rust. flakes of paint coming off inside is worse than doing nothing.

I'm curious what you came up with ? Sort of same situation for me except engine is on stand. I wire brushed and wheeled the block which had much deep rust. By had used a pointy tool by hand for all areas I couldn't reach with wire wheel. Blew off with air and with small paint brush applied Ospho. Wiped all after a few minutes. Will paint later after I clean head areas. I hope it sticks.
