Crankshaft preservation

(Art Ford) #1

What’s the best way to preserve an unused crankshaft? I used to just use WD40 but over time surface rust appeared. I am debating wrapping journals in electrical tape or painting them. I have to assume all these cranks will need to be ground but don’t want them to get any worse than is necessary. These are 3.4 cranks.

Heavy grease, slathered on thickly, on a dry journal.

I cleaned mine, then sprayed it with ACF50, about 2 years ago. Setting in shop and still looks new.

I have one crank and two cams, used motor oil brushed on and then plastic bagged with tie wrap, still good after 15 years.

Cosmoline. The military used it and probably still uses it, to protect stuff.

Didnt even know it was still available: brilliant stuff!!!

Looks like Cosmoline get the nod. I think that’s what it is all about. I too am surprised it is still around and glad to see it in a rattle can.
Thank you all for your answers.
