05 Grand cherokee Air box question
I have an 05 grand Cherokee, love the truck. Today i was looking at the air box and i came across a thin hose that is connected to the side of the box, I opened it and there was oil in it. I'm wondering if this is normal or something is up? Much help would be appreciated!
Think that's the hose you would install a catch can to.

If you have not changed the PCV valve within the last 60K miles, it's probably time. On the HEMI, pull the valve (1/4 turn counter-clockwise and lift out) to verify it is internally clean and that the valve assembly "rattles" when shaken. After a while, the internal spring probably relaxes and the valve doesn't function correctly. The other engines tend to have them on the driver's side rear and just pull out.
I try to inspect mine every other oil change or when I empty the oil catch can.
They are $25-$30 for the HEMI (and much cheaper for the other engines), depending on where you buy. Should be a 15-min. fix.
