Differential Breather Mod for Dummies (Pics)

They are already brought up high to the engine compartment.

 

perfect, thank you guys. I am definatly going to do this mod

 

Thanks to neubs for the write up. Just did the mod today. One thing i noticed-- The old breather was almost spring loaded or something. When I blew through it, air would go out, but when I tried to suck air through it, it would just shut and wouldn't allow any. The new one on the other hand was different- it would allow air though it both ways. I also looked underneath the hood to check what the other breathers were like and found that one of them is like the new one (non spring loaded) and one of them is like the old one (spring loaded).
Whats the difference, and why does the mod call for the non spring loaded one?

Thanks guys

 

I have no idea why they would have a non spring loaded breather. The pressure will go out and nothing will go in with the spring loaded one. Isn't that what you want to happen ? I used to take mine out and clean it up on my 1st gen to make sure it would work. My brother in law had to replace the seals on his and I didn't want to do that. I think I'll do this mod when the weather get better.

 

Watch the video at the begining of the post with the aussies to answer your question

 

Thanks. The embarrassing thing is, is that I watched it this morning before I did the mod. I guess i wasn't paying very good attention.....

 

is there anywhere else to get these unions other than the dealer or dealer website?

Somewhere where this would be in stock?

 

Not sure about local auto parts stores for the OEM stuff but you certainly get the fuel line and clamps from a local place. You could order union and breather from Toyota of Dallas: http://www.trdparts4u.com/Scripts/default.asp

And while you are at it, you could order some oil filters and get free shipping on the order.

You can always use the filters at a later point in time and at least you will not have to pay for shipping. I just did this when I needed some spark plugs and they shipping everything at no additional cost. Hope it helps.

 

After the rains we just got where I now live in Arizona, and flooding I had to traverse going to work. I think I may be doing this mod on my Taco. Good write up and info.

Thanks

 

Im gonna try this this weekend

 

i ordered the parts thru my local dealer and i was surprised how cheap they are. less than twenty with tax on it. have to wait till thursday though to pick it up.

 

Just finished this mod; thanks for the great write up. I bought 10ft of hose and did the oil filter hose mod at the same time.

 

Subbed.... doin this next week!

 

Awesome job sry for my tardness but does the front diff have a breather also? And does the tranny?

 

Yes, both in the engine bay.

Any one have an idea Why ??? the FJ has two breather in the back ???. One for the differential with another for the locker ???? I have four friends with FJ's and I tough that they have the same (similar) rear end. Talking about OR model.

 

So my breathers are in the engine bay? Does anyone have a pic to show cause I don't see them

 

Look on the left (driver) side close to the fender. Sorry, no pics.

 

Okay thank you much Virgilus

 

Pleasure,
