Could be a few reasons, and can't be pinpointed without me actually seeing it "in action". But here are the most likely reasons, in order of likleyhood:
1) Spark plug not tightened to proper specs. Fix: tighen plug to proper specs with torque wrench.
2) Spark plug "washer" bad or gone. Fix: Replace washer.
3) Spark plug seals bad. Fix: Replace spark plug.
4) Bad threads in spark plug hole. Fix: Retap, or "Helicoil" it.
5) Crack in head near spark plug hole. Fix: Replace head.
