    We ll I just freshened my boys 440 in his demon. Went to the track and after a few runs it started smoking blue out of the right side, pulled the plugs all looked great till #7 wet oil on it. Heads were re-worked at the time of refresh. I thought maybe an oil ring got messed up so I pulled the piston and it is fine, but I put a new oil ring on just in case. Put it back together and same issue, I'm thinking head issue? Any thoughts? Thanks

    Could be pulling oil through the intake port if the intake isn't sealing.
    I've had that happen a time or two.

      New rings?

      Did you follow a break in procedure to allow them to fully seat?

      Non-synthetic oil for break in?

      Rings are usually seated during first heat cycle.

      I'll check into that, heads are heavily ported and have had some epoxy work done in the push rods areas, maybe a leak?
