I changed both grommets after having a little bit of oil here and there on the garage floor, problem solved.My thoughts exactly. I wonder how many good RMS seals have been replaced due to a PCV gasket.

I wonder if I used the wrong parts, they were Dorman, but after I switched them out I have high idle. Here were my parts:I just fixed these yesterday! The rubber grommets were totally rotted out and pressure was pushing oil out of the seals.
The plastic elbows were super brittle, so what I did was break the edges of the elbows that sit over the grommets (honestly it’s kind of inevitable), shove a flathead between the elbows and the grommets, and pop the elbows out. The grommets were easy to get out after that point. Others have mentioned there are baffles in there. Forcing the old parts out leave little pieces of plastic and rubber on top of the baffles, so make sure to get all of the little pieces out.
I bought Dorman parts from O’Reily’s and I have to say the grommets are MUCH beefier than the OEM ones. Seating everything was simple and now my valve cover has no leaks View attachment 131074
Wait, did you use the same black PCV elbows for the front and rear?I wonder if I used the wrong parts, they were Dorman, but after I switched them out I have high idle. Here were my parts:

No, I only changed the rear so far. The front one is different, it’s a Crankcase vent tube.Wait, did you use the same black PCV elbows for the front and rear?
Thats your problem Despite what amazon says, this is the one you need for the rear. The smaller hole is a metered orifice that restricts the vacuum. Too much vacuum in the manifold causes high idle.No, I only changed the rear so far. The front one is different, it’s a Crankcase vent tube.
Geez. Well thank you both. Amazon has wrong info. I have one on order now. Should be here Monday. Much appreciatedThats your problem Despite what amazon says, this is the one you need for the rear. The smaller hole is a metered orifice that restricts the vacuum. Too much vacuum in the manifold causes high idle.
I know this is the right one because I matched this part number with the one I bought from O’Reily’s.
Ok, I filled out a return for Amazon and they said keep it.That one you have can be used in the front. I had that same one in there (front).
Time to replace some Vacuum tubing as well, Friend. The line from the CCV to the Intake tube is rotten. Those cracks are air leaks..and if you have air leaks there, you're not getting the ventilation in the crankcase you should.I just fixed these yesterday!

Hit them with a heat gun and they come out fairly easy.if old and dry hardened they can be a bugger to pull and it might break apart on you.
This is where I’m at. I have an 06 and want the right part number for the rear elbow, anyone know if the rear across years are all compatible? They look the same minus the lobe that locks onto the valve cover.For the 2005 there is a lobe that rotates back into a groove on the valve cover. Did your new pcv elbow have that oblong lobe?
Thanks, for the numbers. I’m aware front and rear are different. I just didn’t know if the rear part numbers translated across years. It seems you can find the rear (smaller hole) from earlier years with no flange but it looks like Mopar discontinued it for later years 05-06They are different. The front is completely open and ties to air box. The rear is smaller diameter (so different grommets) and has a tiny orifice inside the elbow. Autoparts stores claim it is the same grommet. It is not...
Found the rear grommet at quadratec mopar# 53013743AB.
Never located a new elbow (mopar#53013743ab) but managed to salvage mine and the new grommet made a world of difference in sealing.
For reference Front numbers are 53030497 elbow and 2946079 grommet. 05 and 06 are coded as the same.
