It stopped raining so I thought I'd take a quick 30 minutes and replace the PCV valve on the 2015 JK 3.6.... 2 hours later ...what a PIA
I'm convinced Jeep purposely engineered the passenger side with an oversized battery box and routed the hoses on the passenger side to block easy access and deter DIY.
Couldn't pull the hose free from the PCV valve because it was too tight a fit for my hand and it wouldn't allow for a straight pull up to remove the hose, I crawled underneath and with a long 1/2" wood dowel pushed up on the edge of the hose to remove it - it popped off easily with a straight push up. A hose spoon pick type tool probably would've made it much easier than crawling underneath; while I was under there I looked to see if I could get to either of the T25 screws holding the pcv valve and it was a big no. At this point, I'm pretty sure I heard my neighbors shut their solid doors when I started swearing LOL
I had a relatively small flex head 1/4" long ratchet and managed to break the screw loose after numerous tries, finally got it using one hand.
I used my finger to hold the ratchet head on the bolt and once I got the ratchet to grab a tooth, I was able to break it loose then was able to unscrew it out slowly with my fingers. Had to remove the wheel and fender to access the bottom screw - also a PIA getting a T25 torx to stay in place.
I would recommend getting a stubby 1/4-inch micro ratchet combo socket and bit driver with a short draw of 90-teeth or more (shorter in length than the Mopar hardtop ratchet tool) as there is no space between the firewall and the valve bolt to use normal tools, only enough space to use one hand to hold the T25 on the bolt and turn the ratchet.
I replaced the PCV with a Dorman PCV and it came with 8.8- 8mm hex head flange bolts, if you get the Mopar pcv valve and it has the T25 screws, do yourself a favor, head to Ace Hardware and replace the T25 with the proper sized hex head flange 8.8 bolt or just order the Dorman valve.
The hex head made it much easier to hold onto and get them finger started, also made it much easier to get a socket to stay on and tighten them; doesn't take much to tighten them. Again, a ratchet with 90-teeth or better would make it easier and faster to tighten than a standard 72-tooth ratchet.
I figure it took 1.5 hours to remove, most of that time trying to get that upper T25 screw off and about 30 minutes to reassemble everything.
Have fender clips on hand unless someone has a better suggestion on how to access the lower bolt.
This is going to make replacing the rear leaking axle shaft a cake walk
