<VV> Cleaning Piston Crowns

[corvairduval at cox.net]

I don't know a best way, but...

I strongly recommend you pull the pistons out of the engine (by removing
rods from engine) to examine them closely for cracks.

If you find none, you can put them right back in, just keep the same
bearing shells in the same locations.

The OEM pistons crack a lot. Especially around the oil ring groove. This
causes the top of the piston to come off.

 I'm preparing a spare engine for my 65 140 Corsa and don't want to tear 
 things down further than I need to. What's the best way to remove carbon 
 buildup on the piston tops without removing the pistons and rods from 
 the engine?
