Top plug that has a tube plugged in
2006 unlimited 4.0 engine has a plug on the top of the engine that is leaking & must be replaced.
My guy says he had never been able to find that part.
How do we find this part?

Re: Top plug that has a tube plugged in
Any chance you could upload a photo of the part?
Sounds like the PCV valve to me, but that's just a guess (and very easy to replace).

CCV. There are no PCV in 4.0
You cloud buy new gaskets or try adding an o-ring to the gasket and CCV
