I've always used decarbonising brushes in a pillar drill to clean valves, just seemed logical to me

My method is to simply fire up the wire wheel on my bench grinder and hold the valve against the tool with either with my fingers or some pliers if I'm feeling a little out of it. That works away all the dirt and grime and carbon build up and I've never seen it scratch the valve.

Finally, that was a lot of work for so little. Nada paint left.

It's basically another kind of attachment you can put on a bench grinder. Good for cleaning up your sharp edges when grinding.

Get your valve seats re-cut & lap the valves in, you know lapping in valve?

Now be sure to take a long tube nozzle on an air gun ad blow out all sand from deep down the holes. Any left in there will come back to haunt you.

@Scottieh, Pictures explains the most. I have one of thoose for my drilling machine, thanks.

@Mezo, I knew there was something to do with the valves but I have to look up how on Youtube. smile:

@Xtrider, yes did that last time for surely 5 minutes a piece. Will give them same treatment again and maybe a bath too. smile:

Engine parts from the new batch.
What do you do with parts that rusty, junk them?
Or is it a way to rescue them?

Every part is precious, every effort should be made to rescue them.

Looking at the picture there are only a couple of parts in "danger". The camshaft and the valve keepers.
The rest just need wire brush and solvent.

Google 'removing rust by electrolysis'

Simple electro-chemical reaction similar to electro-plating, but in reverse.
You can do it home with a battery charger or other DC supply.

So I stopped worrying and lo and behold, things did get worse!
