Oil keeps pushing out of valve covers flooding my spark plugs with oil. Already replaced valve cover gaskets twice, how do I fix this problem

replace heater bypass vale leaking antifreeze, replace head casket leaking oil, replace oxygen sensor bank 1...yes it happen to me too..
bought the car , week later, engine light came on, replaced oil cooler and antifreeze still mixed with motor, currently replacing heAD GASKETS/ what a money pit
Oil mixes with antifreeze. Radiator has a leak, upper drivers side. Car leaks oil. Steams from under the hood only some times. Transmission slips when going into 3rd, so I have to drive it like a manual. Driving lights/headlights refuse to go out and drains the battery. Do I keep this car or scrap it. Body and interior is in good shape and it has such low miles.
Valve gasket needs to be replaced, leaking oil. Replaced the radiator at 100k miles becuase of leakage.
oil leak's it seem that it's not circlulating cause I see a pluddle of oil inside the engine via the spark plug. then it shutting down
Oil is leaking into the coolant.
Replaced valve cover gaskets, (also used gasket maker to be sure seal is in place). Took care of the leak. The oil cooler still needs to be changed. Burns oil like crazy causing smoke. Runs fine. Changed spark plugs as well due to the engine burning oil hotter.
