my car has been giving me codes for vacuum leaks for a while now and upon cleaning my throttle body i found ALOT of oil up in there. so i went to clean out my pcv valve or pancake valve or whatever and when i took it off it spilled a measurable amount of oil all over me and the car and the ground and made a serous mess. i also noticed that i can blow into both sides of the valve an nothing happens, should'nt it be a one way valve? and could this cause a big enough vacume leak to throw codes and cause rough idle?
