    And this is what they look like after 2 hours, a razor blade, a brass wire wheel, and a 3M bristle disc:





    The amount of SHIT that was built up on top of my pistons was frightening. I can't even imagine how well my car is going to run once I get everything put back together...

    I'd like to add, before anyone freaks out, that the brass wire wheel was only used to take off the REALLY hardened carbon shit, and not used directly against the metal. The 3M bristle disc was reccomended to me by a local German Master repair shop, it's what they use, and it worked great!

    Ooooh SHINY! :nice::nice:

      On a positive note, you also lost a bunch of little ridges and creases that get hot and reduce detonation margin.
