Reddit mentions: The best automotive pcv valves & breathers

What milage is it at? Sounds like its misfiring. Very common that this is the ccv. Around every 100000 the ccv needs to be changed. This helps regulate oil timing of the throttlebody ect.

This is pretty cheap for a car saving repair if this is indeed the problem.

The replacement is hard but there are some good youtube videos. Good luck pal

A while back, I noticed (with your help) the PCV Elbow was broken on my 99 Dodge Durango SLT. I ordered the part, as well as a new breather tube and grommet.

However it seems as if the bottom part of the PCV Elbow does not fit into what I imagine the crankcase is?
(And to be fair I had to break the old one further to get it out)

It looks to me like I'm going to have to take the top of the crankcase off and put the PCV Elbow in the through the bottom, then put the grommet on and connect the breather hose?

Does this seem right? If so, is it an easy job?

What are the risks involved? In other words, what could I fuck up?
Do I need a sealant for when I put it back together or anything other than a socket wrench to pull it off?

Any advice would be helpful.

Thanks!

• TL;DR: Do I need to take apart the crankcase to insert the PCV elbow & can a novice pull it off?
  
  (EDIT: Bonus Question: Although I've tried to avoid using the vehicle until it's repaired, in the cases I have had to use it I've noticed the thing is DEVOURING gasoline now. Does the fact that the breather tube isn't hooked up at the moment have something to do with that?)

Still pretty sure it's this http://www.amazon.com/Dorman-47079-HELP-PCV-Elbow/dp/B000JZIXIW/ref=au_pf_ss_1?ie=UTF8&Make=Dodge|40&Model=Durango|303&Year=1999|1999&carId=003&n=15684181&s=automotive

That's the rear PCV valve, linked here:

If you are swapping both, I'd recommend the grommet as well:

It looks like a PCV valve. https://www.amazon.com/Motorcraft-EV98B-Positive-Crankcase-Ventilation/dp/B000C5HJ3O

My reader is busted so I'll get it reset again tomorrow, but the first time it came back within the same day. Maybe 2 hours of driving time. It's just so weird I don't have a normal idle feel yet the CEL is on.

I'm leaning to it being the fact that I cheaped out on a $40 Chinese PCV, but everything checked out on it from my non-professional eyes. I couldn't justify the $118 from VW Amazon or $150 from DAP

Edit: I may try replacing the diaphragm first and seeing if that works. $20 , if not, I'll shell out the $100+ for the VW part I suppose.

As was mentioned it's the Crank case Vent and tube. Here's the parts:

Vent: https://www.amazon.com/gp/product/B000JZIXIW/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Grommet: https://www.amazon.com/gp/product/B000C5I49C/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Tube: https://www.amazon.com/gp/product/B000630HOA/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1

They might be a little different as they're from my '94 Grand Cherokee, but it's the same engine. You'll want to get all three as the valve is likely to break when you try to remove the tube, and the grommet will probably need to be cut out of the valve cover to replace the vent.

I had that same problem with mine. Replaced these bastards, the oil cap and the back pcv valve and hose and it stopped. Those seals wear out an start seeping oil from the top of the valve cover which coats and preserves the engine.
