[Vwdiesel] Decoking pistons

[Bryan Belman]

Looks re-buildable, but sure is ugly now.  Wow, never saw rings like those, have 
to see what things look like after they are given a good bath.
Are you just going to hone the cylinders with the block in the car?  you must 
have dropped the crank already.
