I've had a few oil drips since I resealed the filter adapter, but definitely a smaller number than before.

Since the weather was nice over the weekend, I was able to get to a wand-type car wash and wash a bunch of gunk off the front of the engine and the undercarriage.

Later I was able to see where I'm now getting oil out. Bleh.

Focused on background connection:


Focused on "belt bridge" casting supporting the resonator delete pipe:


It appears that oil is leaking out of the joint from the compressor discharge pipe on top of the engine to the resonator delete pipe. These o-rings are supposed to be replaced every time the joints are split... Is that for realz?

From that joint, the oil flows down the back of the resonator delete pipe to get to the "belt bridge" small cast bracket that supports the resonator delete pipe and straddles the belt.

Of course the real problem is that there's enough PCV oil in the compressor discharge pipe to leak out from that joint in the first place.

Do the PCV valves on the valve covers actually fail? Or do they just not work well in the first place?
I'm about to install my Mann & Hummel ProVent behind the right front wheel house... just have to be sure that won't interfere with the Isuzu snorkel I'd like to snag for this vehicle

Edit:
Also got hott new Bilsteins from Kolak, as user on JeepForum who runs a parts business.



Spring perch installed to the middle of the three locations:




It drives SOOOOOOOO much better than when it had worn out/blown front struts!
Of course tightening up the front serves to emphasize how trashed the rear suspension bushings are and how they detract from the driving experience

I'm still getting some oil drips from the joint between the turbo discharge pipe and the resonator delete pipe. Service documentation says to replace the o-ring every time one of those joints is separated, regardless of how new the o-ring is. Naturally I didn't bother since I'd just replaced it when I did the oil cooler reseal and intake manifold swap... and now it leaks oil.

Except... there shouldn't *BE* oil there, at least not in amounts enough to leak drips.

Per advice on the Jeep Forum I just replaced the PCV valve. Apparently it's a 30k mile maintenance item. That's the very first thing I've found on this vehicle that's easy! :ROFLMAO:

All this time I thought there was a gaping hole in the valve cover under the PCV valve... but there isn't and the mounting screws are just mounting screws.

Somewhat predictably, my old PCV valve was missing the o-ring where it plugged into the cylinder head.
