Hi all, just wondering if anyone can tell me what this bracket is for behind the rear axle? Noticed a while back when I was under the truck it was hanging down and I wasn't sure what it is for/ if I should fix it haha. Thanks! IMG_2438.HEIC

Thanks a million cruiser54, that's exactly what I needed!!! Huge thanks to Eagle too, because now I understand why I need those parts (and know the answer to the argument regarding whether its a PCV or CCV ;)!! Keep up the good work fellas.

Thanks Wounded_Fighter! Exactly what I needed. After googling engine bay pics it looked like the line should go to the vacuum harness, so you helped confirm that too! Also, looks like you decided to cut off the end of the breather tubes on the inside of the valve cover...been hearing good things about that so I think I'll do the same!

All good! Makes sense now. Thanks again! And something I should've mentioned earlier is that I was skeptical that my system is routed properly, because in the first thread I mentioned above they list these as the correct parts for the front valve, which appear to route the hose through the vacuum harness?? https://www.rockauto.com/en/moreinfo.php?pk=586584&cc=1181720&jsn=390 and https://www.rockauto.com/en/moreinfo.php?pk=586585&cc=1181720&jsn=391

Yes to what part of it exactly? That my system was not set up right or that the system was obviously clogged? Thanks for the reply!

Hi everyone! I've been the proud owner of a 1990 MJ Pioneer with the 4.0 engine for about almost 2 years now. Don't have a lot of mechanical know-how, but a huge desire to learn -for which this site has been a huge resource. Anyway, I'll start off by saying that before starting a thread I took time to look through a large number of other threads about PCV/CCV questions, and after reading quite a few I still have some questions. One of my next purchases will be a good shop manual, but I'm in a small town in northern Canada so I don't want to wait a few weeks for that...anyway, here goes: I need to replace the front PCV/CCV valve and hose. I had removed the one end of the hose from the air box and routed that end of it below the engine because I was tired of my air filter getting full of oil. However, I was also having issues with the PCV valve popping out of the valve cover. When I was flushing my coolant system the other day, I realized the valve and hose were completely gone -it must have popped out at some point in the last couple weeks and fallen out completely along with the hose! Haha. Reading the forums the last couple days, I now realize that the front valve us supposed to be the intake valve, and the rear is the escape valve -so the front valve popping out and the oil in the filter means that my system was clogged and not working properly (but you guys already knew that haha). All that being explained, I want to replace both the front and rear PCV/CCV valves and hoses properly. However, reading this thread made me wonder if the way the hoses were when I bought the truck was correct: Secondly, in the other threads I've read such as the one linked above and this one: Everyone is saying that the front valve is not a PCV, but rather a CCV and that the valve is just an elbow. As you can see in the picture above, my valve was not just an elbow, it was a small valve with a metal lower sleeve that simply fit into the rubber grommet...which again raises my question as to whether this system was set up properly on my truck when I bought it. And if anyone has a links to the parts I need to order, that's the ultimate goal here. And if you've had the patience to read all this, thanks in advance for your help! Just a rookie trying to educate himself!!!
