 Topic: another engine rebuild question
Posted: 14 Apr 2011 at 10:13pm |
I asked about cleaning to "o" ring seat several days ago and got a lot of good ideas....thanks guys. Now, someone mentioned electrolysis to remove the scale from inside the block, any ideas what that would do to the machined surfaces? I was actually thinking of putting the oil pan on, filling the block to the head surface and dunking some electrodes through the sleeve holes

It won't hurt machined surfaces. It only works on the rust and crud. I never thought of doing a block like that. Don't see any reason why it wouldn't work just make sure you hook the cables up right or you'll have nice clean electrodes and the block will melt away.
I stood my block on end and put it in a 55 gallon plastic drum. I put 4 wore out lawn mower blades around the outside of the barrel and rotated the block about once a day, while cleaning the electrodes.
Actually the blades were inside the barrel. LOL

Like Charles said, electrolisis will only affect the rusted areas. I had never thought about it on a block either, but I think it work good.

If you do this you will need to remember to repaint the inside of the block when it's done. If you don't, it will bleed oil through the cast.

Lou,
You could smear some heavy grease on the machined areas just to protect them.
My girls and I do some metal detecting once in a while and when we dig an old rusty horse shoe or something I usually throw it in a bucket full of really thick old cooking oil, last year I took a couple of those out to put in the electrolisis tank and didn't clean them very good first, it wouldn't do anything until I got that gunk off.

An hour with a wire wheel will clean it like my picture above. I love it when people want to take weeks to do an hour job. Gives me a chance to keep the dandruff loose. It's yalls time, take as long as you wish.
Never painted the inside of a block that I cleaned and never had any bleeding problems.
Of course you might have guessed that I have never put oil in the radiator to see if it would bleed oil thru the water jacket.

Dick has a good point. I chose to go the electrolysis route because at the time, I was working 10 hour days 6 days a week and wanted to keep going on the engine. You can weigh your options according to your situation once you are aware of the options. You can get all kinds of wire wheels for a die grinder. Some can be pretty aggressive but if you use a flapper wheel don't dilly dally in the bores with it. Your bores don't look bad to me, just the beveled lead in needs to be smooth to allow the o-rings to slide in unhindered.
Dick, I use the cheap blue shampoo to minimize my dandruff. LOL
I didn't paint inside my block either. Thought about it for about 10 seconds though.

Tuff to find a shampoo that will cling fast long enough to do what it is advertised to do.

ROFL, So you don't have any trouble with upper lip dandruff? In case you didn't notice Dick, somebody is paying more attention to you than the camera.

I'm with Dick on this one. Either wire brush on a die grinder, or rabbit turd hone on a drill. Do it in a few mins instead of days...

I would probably use a wire brush and take less time too, but electrolysis should work if you go that route. It is just something I never thought of. Humm...... now I have.

Dang, Dick, you have discovered one of my very few flaws! I am a master of over engineering a task, taking days to a ten min job in search of a better way.
Alright, alright, flapper wheel and wire wheel it is!

A wise man would use a face mask to clean out the scale. I tend to plan ahead a few weeks and let my nose hair grow long and thick along with the stach to block the rust dust. Ya know, to each his own.
