i have always used a wire wheel for the head and most parts for that matter, also the crowns of the pistons even though i have been told not to. i use an old broken piston ring sharpened to clean out the ring grooves. follow everything up with some brown scoth brite with some citrus degreaser or solvent and you will have nice clean parts. :{_}:

I was taught in Auto Trade School (many decades ago) to scrape the carbon off of pistons and heads. Wire wheels or sandblasting as discussed earlier can create a texture that carbon will cling to causing build up in the future. That being said, yeah, I use a wire brush or wire wheel. :oops: There are also many liquids that will dissolve carbon, like Sea Foam. I don't know well that would work but if you have something like that, it might be worth trying it out. The mating surface should also be scraped clean. If you are having the block bored, take the head to the shop too. A good shop will deck the head and boil it out with the block.

I have a cracked head that I am going to experiment with and put it in my electrolysis tank :idea: :) And if I can find a really badly stuck C-60, I am going to try that to :!:

Probably the easiest way for sure is to use a good twisted wire cup brush in a hand held grinder.

I have the block for you !

Now, getting it to you may be a problem. I live about 1 hour from Cecil. I think you live somewhere above the Arctic Circle :lol: .

Water got into the number 2 cylinder through the exhaust port. This engine was part of a tractor sitting in a back corner of a field for a few years with an uncovered exhaust pipe. Maybe it is too far gone for what you want to try.

Em and I will be at Cecil's in October :wink:

And yes I used to live above the Arctic Circle a long time ago ... back when I was in the Navy -- CFS Inuvik and CFS Alert. Now I just live about 2 hours from Calais or 5 from Bangor.

More for an experiment to see if the tank will free it up. Be fun to try anyways. Nothing ventured, nothing gained.... :D So will you be at Cecil's in the fall :?:

I do plan on being there, but I have planned on being there the last couple of times and did not make it. If you are really interested, I will make sure it gets to Cecil's if I am not going to be there this fall. That is assuming that Cecil doesn't mind me dropping off some trash valuable tractor parts in his yard.

I have always used a paint scraper to good effect You just have to be careful to hold the end flat and not dig in a corner of the blade and score the surface.

Think I still have a wire-wheeled one (on top), and hand scraped with a brass scraper on the flat in the shed. You're welcome to it, Ken. Might have a micro-crack on the top, I don't recall which one was good and which one was bad. Looks OK though.
