Taken from Shadow-Warrior's post
Historic Background For Doing This MOD
Toyota has moved the Front Differential and Front Actuator breathers up high in the engine bay already for you, but neglected to move the Rear Differential breather, E-Locker breather, Transmission & Transfer Case Breathers. Those with the MT will only have one breather in the engine bay area, you don't have the front actuator like the AT's do. I decided to relocate the breathers up high too, I would normally run all breathers inside the vehicle, but since the front is already in the engine bay. I decided to run the rear differential & Locker there too. I want to say this has been a collective effort by many on doing this Breather MOD.
I took quite some time to decide how I wanted to go about this mod. The major issue I had was the fact that I am not a fan of using barbed hoses or the red filter which Shadow-Warrior used. However, I saw ToledoFJ's post on how he purchased a kit which used pneumatic quick connect fittings. Having used them in the past for quite a bit of automation work I was sold that this was the way to go. These are air tight and less likely to leak than threaded or barbed connections. Unfortunately I couldn't afford the $200 price tag on the kit which Toledo had.
So I went about designing my on kit with manifold. It took quite some time to find and obtain all the parts for my design, but this is what I came up with.
The E-Locker ties into the Rear Diff 'T' and then is routed up to the jack compartment
The Transmission and Transfer Case are routed from the rear of the engine back along the passenger side frame and across the rear axle to the jack compartment.
The Manifold is mounted in the jack compartment and has a polyethylene breather (blue breather pictured) attached the the manifold which is vented to the atmosphere. I went with the polyethylene breather instead of the typical filters you see because it offers better filtration over the alternatives and makes drawing it water less likely.
I plan on putting silicone around the two grommets which the hoses go through to seal everything up. I may also add some heat shrink around each of the connects.
Also just an FYI. Not sure how many have seen the fitting they use on the 08's for the transmission, but here it is. Slightly different than the breather that they used on the 07 models.
It took a little over an hour. The most time consuming was getting to the breathers behind the engine (have enough scrapes to prove it) and deciding how I wanted to route the pneumatic tubing from there.

-100°F to 175°F. It doesn't touch the engine or anything, so all you are concerned with is ambient temperature which doesn't reach this high. Heck my old Turbo Civic barely reached 190 degrees and that was with an open down pipe.
Just finished the install on Gregf's FJ. I didn't take any pictures, but the breathers on the 07's are more of a pain to get to than those on the 08's. Still worked without any issue on the 07 though!
Great Job, very clean install. Do you have any info on the parts cost, part#'s, manufacturers' info. Thanks for posting, and in advance for the info.

I don't have all the details as I was keeping track of everything on my work laptop which I left in the office this weekend. Basically I'm planning on making it a kit like CruiserLarry's dual battery kit or the 'bandi' mount. The main issue is I had to have a couple of the parts rapid prototyped (FDM) because they weren't available in the appropriate sizes. Luckily I've been able to bum extra space in the machine when they were running through some other people's orders at a place I used to intern.
very nice, and clean install. Much better than my got r' rigged mod. keep us updated on this kit idea i think putting it together for every one is a great idea.

It was great to finally meet you. The kit is very well thought out and clean. The install is very straight forward. GR8 KIT especially for the $$$. Thanks for all the help.:cheers:
Glad to hear you are happy with the Kit. I plan on putting some heat shrink around the connections on mine when I have an opportunity. If I have some spare heat shrink left over I can swing by and do yours as well.
Wondering where in the GCC ( Saudi, UAE , Bahrain,...) i could go with my FJ to get some propper mods in..?! Lift, bumber, snorkel,...
Contacted the ARB dealer in Dubai, seems they are out of business..
thanks!
I recently put some White Knuckle Rock Sliders on and the wife is now wishing there was more of a step. I don't want new sliders, but I'm wondering if anyone knows of a decent clamp-on/bolt-on solution?
I've done some digging and found there used to be someone named streetacos that made them...
Were proud to introduce TJM Stealth winches. These are in our opinion the best bang for your buck. But with that being said I will be testing one in our company 4runner over the next several months to confirm what I already believe.
When TJM set out to do a winch they could have done just...
Yesterday I had the opportunity to install some brand new skid plates from Ricochet Offroad right here in Utah. Just figured I would mention a couple notes about the install process to help those doing future installs.
So the instructions are pretty good that they give you but one thing I am...
I've been considering the addition of a winch to my front bumper. This would be just for safety. I've been using the FJ for about 2 years and only once I had to be winched out by another vehicle, but in that case, having my own winch would not have helped. I don't intend to do anything that...
