08 HHR running hot, trbl starting, pressure change in brakes, please help!?

I blew a gasket because oil water mix. I used the $80 bottle of sealant, changed the oil, it started running like new! A week later starts running hot it gets so hot that the water comes out of the overflow and out the  (I’m gonna call it) the breather hole! This happens almost as soon as I start the car! I’ve replaced the thermostat and used a tester to see if exhaust Fumes in coolant, it didn’t test positive! I’m at pullapart now gonna replace the temp sensors. Any and all suggestions are much needed!! Thanks!

    The sealer just added to your problems.  While a head gasket may have solved the problem, now you'll have to completely disassemble the engine and have it boiled out.

    Head gasket is shot.  You need a new engine.
