70-914-6 Clean Up, UPDATE - Paint and Prep - Black and milky white-ish Options

1970, 914-6, 93K miles - excellent shape, very minor rust

I will post to this thread occasionally as I move through this project, I have asked for guidance and received many good thoughts from this team - thank you 914World

I am in the midst of removing the engine and transmission. All original. There is oil everywhere, not flowing but seeping - seems that the valve covers are not tightened or have loosened with age. Here are the first pics:

On the rack - hopefully not for long:



Shift Assembly is very clean, no wear, bushings are in good shape but all of them will be replaced







Heat exchangers have no holes in the pipes that I could find, the surrounding tin has been treated with anti-rust leakage - perhaps this was the plan in Stuttgart?







No plans to change the exhaust system - any guidance as to cleaning or preservation?

All comments and guidance appreciated - engine coming down on Friday

Your flappers look pretty good. Something that might be worth checking is the inside. The springs and the sealing surface. It wasn't obvious, but the springs on ours were broken. There is a thin one that keeps the disc aligned. This kept the flapper from smoothly going through its motion because the disc inside would bind. The disc itself seems to be fiber (maybe asbestos?) over mesh and can disintegrate.

The flappers are in really good shape - both springs are in great shape, I beleive I will have them vapor blasted and then powder coated. I am experimenting with the 'secret sauce' and its effectiveness - interesting product - low grade (ph) acid solution.
