Get the right parts in it first, make sure all those hoses for the evap system you took off are plugged up and change the PCV valve.. If itÆs still doing it then you should pull the radiator cap and see if the coolant is gurgling while the engine is running.. If it is you have some major problems.. a blown head gasket at best or a cracked head and/or block would be the worst! If the coolant isnÆt gurgling then I would do a leak down test to determine whatÆs wore out.. if you have blow by coming out of the oil cap, pressure has to be leaking past the piston rings or the valve guides and valve sealsà do your leak down test with the valve cover off and use an mechanics stethoscope with out the metal end ( just the open tube) and listen for air leaks.. if the sound of air is coming from the oil return holes in the head then your piston rings are leaking.. if its coming from the base of the valve springs then the valve stems and valve seals are leaking..
