Sounds like the rings are shot. What color smoke?
blue = oil
white = water
black = gas

If it is blue which it probably is since you have blow by from breather and the dip stick tube then I don't know why anyone would tell you the head gasket because that just don't make sense.
Feel free to bring it by and I can take a look and tell you whats wrong with it. 727-768-9917 Terry @ T & C Racing
