PCV Valve?
 

What brand would you guys recommend for a PCV valve for a 91 4.0? Also, do I need a grommet as well?

It is technically called a CCV :tongue_smilie:

dorman has replacements as well as grommets in the help/motormite section of your local auto parts store

there are two breathers in your valve cover so make sure you are getting the correct one.

one will have a huge hole in the bottom, and the other has a small pin hole on the bottom... the grommets are the same..

This:

you and your dang pictures! lol

I got lots. Where's your avatar? Want me to supply one for you?

hah I never really thought about setting up an avatar... a bloody knuckle would suit my jeep nicely

How's that? It's actually a .45 caliber bullet hole through a guy's hand. Will it do? I know the guy BTW.

hahaha speak and it shall appear! That' a pretty serious bloody knuckle!

Uh yeah... 45 through the hand. Missed all critical stuff. The dork is really lucky.

.45?? he is lucky he has any hand left! During my time in the army, I saw some pretty serious bullet wounds.. lucky ***

He was pushing on the barrel or something. 10 PM. "Practicing"..Whatever.
