scotchbrite disc with the mini air angle grinder

i also like to use a stright wire brush thats about 1" round and very stiff in the mini grinder.

I use the brush to de-carbon the combustion chambers and valves before R&R them as well.

when the scotchbrite wont cut it then its to the wire brush or wire wheel.

use air to blow cyls clean or a shop vac them out.

they do make a spray gasket remover also,you can find it at napa for a few bux.

good luck and ez on the loony-um
