Pcv Valve Problem

  1. So, I need to replace my pcv valve. My car has Moroso valve covers, and the pcv valve I got from o'reilly's is too small. The clerk told me to bring my car to the store, and he'd just find one that had the correct circumference; because they all do the same thing, no matter what car it came from. I understand his argument, but I'm not sure I agree 100%. Putting an essential part from another car in my car doesn't sit well with me. Other people have said to just put some silicone around the pcv if it's too small. What should I do?
     
  2. Your PCV valve is in the back of your lower intake, not your valve covers.
     
  3. post a picture of what you think is the pcv valve. The PCV is behind the intake and connects to a hose that normally attaches to the bottom of the upper intake.
