V6… I6… bah, you get the idea smartass. It’s a POS leaking oil on my driveway. 
Pulled the rear line and looking inside the valve cover it’s a mess of sludge and crap. Part of me wants just try flushing it with fresh oil but I really think I should pull the valve cover and clean everything up.
Don’t think you can change the PCV valve on these because it’s built into the valve cover from what I was just reading. From the link I posted earlier:
The valve cover on the 4.0L has two breathers on it, the front one is just that a breather but the rear one is a PCV {positive crankcase ventilation} valve, breather, I say breather because the PCV valve is built into the valve cover. And the only way to replace it is to get a new valve cover, but this is probably not your case. What happens is the rear breather is made of rubber and after time it hardens and tends to close up and or plug up with soot. In tern this puts all the engines crankcase pressure threw the front breather and causes it to carry oil through it to the air filter.
Who the fuck designs something like this? Oh yeah, the morons at Chrysler.
Yeah, re-reading that I can see I wasn’t real clear. I mean the majority of the oil leaking all over my driveway was coming from the airbox. I understand it was being forced up from the valve cover, through the PCV valve, down the tube, into the airbox, then onto my driveway.
Don, do you think just flushing some walmart special oil down through the PCV inlet as well as the oil fill and immediately changing it will do the trick, or do you think I should pull the valve cover and really clean it out? Maybe change it with the cheapest thinest oil I can find, run it for a few minutes, then change it again with decent oil? If it was the mother-in-law’s boyfriend I would take joy in the idea of him stranded on the side of the 90, but I actually like my mother-in-law and want to make sure she makes it back to Binghamton. Obviously I’ll be changing the PCV breather and blowing it’s line out with brake cleaner.
