My ka24de with 178 thousand miles puff out smoke , when u crank it up and when u stop and idle. I know I have a bad 02 sensor and it used to it but now it has gotten worse. Do yall think it is time for a rebuild?

coolant. You just blew your headgasket.

That or you're running EXTREMELY rich, which means leaking injector(s)

You can try replacing the o2 sensor, but I doubt that is the case.
