      using oil

      I had this motor built for me. It has used oil since new. I put a different set of rings in it and it still uses oil. BBC 489 cast eagle crank with Keith Black pistons, flattop. Should this piston have buttons, and why can I not find a listing for any buttons?

      Do you have a picture of the cylinders? Also, does it use oil so bad that it smokes? Were the heads rebuilt with new guides and seals?
      A poor intake seal can cause oil consumption as well.
      I had one that would smoke over 2500 rpm. It was the valve guides causing it. On another one, it did t smoke, but used oil. Found it was sucking oil through the PCV system. Installed a baffle in the valve cover and fixed the issue.

      Can you take another pic of your piston? It looks like there is a black ring under the second piston ring. Could just be the way Im looking at your pic. But that might be the support ring for the oil ring pack.
