my cars been throwing lean codes for a while and i’m questioning if it’s my pcv. i have a small crack in my bank 2 valve cover as well as i deleted one side and have a filter to not build pressure in the crankcase. is this okay to do and plug where the pcv line attaches to the intake or should i like not. any help and criticism is greatly appreciated as im still learning and im young and dumb. it’s an 03 gt for reference not sure if it makes a difference
