What exactly causes this, because i put an oil breater on my car, and there is blue smoke that comes out of it constantly, and how do i fix this.

thanks

Majority of the time......rings.

But could be other things depending on your engines health.
Cracked head (from overheats)
Valve seals
Valves not seating well (carbon)

insuffecient seal between the piston, rings, and cylinder wall. any valve related problems won't cause blow by.

Sounds like you need to take the breather off and put the stock setup back on.
