.,? It's hard to read with out these. Blue smoke at start up usually means vavle guides are wearing. Will it stop after a few minutes? I think if the rings are going bad it would smoke all the time. Could be something as simple as a clogged pcv also.

Blue smoke is not gas, its oil. Sounds to me like leaking valve seals...
