Yes.

Fortunately cam bearings are easy to replace. I'd remove the old ones prior to cleaning for a more complete job.
 
Yes, it will damage the cam bearings as they will dissolve. So will the front and rear main bearing grease retainers and dip stick flange that attaches to the oil pan.
 
Electrolysis will work fine on ferrous metals. Anything made of steel will work.
Electrolysis will damage any non-ferrous like Aluminum, Copper, Zinc and cam bearings.
The little plate that attaches the dip stick to the oil pan will also dissolve including the fuel pump push rod bushing.
The main bearing seal retainers on the front and rear of the block will also be dissolved.

Carefully read all the information contained here about Electroylisis and Evaporust.

If your 8BA has squirt holes in the connecting rods be sure to clean them out also. Same with oil passages inside crank.

I would prefer to use a stiff wire flexible wire spiral brush and liquid degreasers like this:

Also consider Shake and Bake Cleaning:

This report makes me hesitate to clean cast iron with electrolysis.

Use spiral wound wire brushes.

would really like to do the shake and bake, are there any shops in illinois or iowa that does this?
 
hotcoupe: That method you showed is the best. It makes sense. Was not aware of it. Thanks for posting.
 
It would be helpful to know the definition of "electrolysis" as discussed here. The "electrolysis" process I'm familiar with and have used quite often with great success is nothing more than plain water, Arm & Hammer washing soda, and a low voltage power supply and does a terrific job of removing iron oxide (rust) from iron and steel with virtually no harm to the part being cleaned.

I have never heard that this process would dissolve the soft metal on cam bearings and other soft metals, but then there's a lot I don't know. :) Also, this electrolysis rust removal process I refer to works very slowly and only attacks the iron oxide on a "line of sight" basis.

Is it possible we might talking about two different types of "electrolysis" systems? Perhaps I missed something so I'm certainly open to learn more.
 
I have found that electrolysis to be messy and inefficient because it works "line-of-sight" only. Never fear however, as it seems that someone has finally cracked the formula for "Evapo-Rust" and it can now be formulated at home very cheaply. See this thread on the H.A.M.B. : https://www.jalopyjournal.com/forum/threads/rust-removal-tools-or-parts.1322229/. An outfit called "Beyond Ballistics" developed it and has quite a good video explaining it, The only problem is that I had a very difficult time understanding the guy;s thick European accent, but I got the gist of it. They did some very comprehensive comparative testing, and it seems they got it. I have always considered "Evapo-Rust" to be the best rust remover there is, except for the price.
