Hello all. Have been trying to figure out a misfire and started with the basics. Went to install new PCV today and found that original valve was loose in the seat allowing oil to pass around rubber seal. It seems the factory install was pushed beyond where it should be seated. While very difficult to get out, was very loose. Or is this how it should be?

Anyone else experience this? I'm thinking it may have caused fouled plugs, or am I way off on my assumption?

Thanks

 

My PCV valve was also difficult to get out. I wouldn't say mine was loose though. Here's a thread on it: https://www.jk-forum.com/forums/stoc...-valve-307717/

 

The PCV valve shouldn't be loose like that. Are you sure the valve cover hasn't been damaged?

Being tough to pull out is a common complaint. It took a huge lever and (I had to call) a 275 pound, 6' 4" friend of mine, plus little old me, to get mine out. I've read that doing it when the engine is hot makes it a lot easier--after my own struggles, LOL!

 

Thanks for the responses. Yes, surely loose. Oil and all was getting aound it, and, yes, a bear to remove. Since replacing valve, running better but not 100%. Not throwing codes yet. Plugs next..................
