T-Case Breather Removal?

[FJ60Cam]

I've noticed the occasional puddle of oil under the truck, but only after high speed interstate travel. When I checked it out, I saw oil seeping from a few places on the t-case. I rebuilt this about a year and a half ago and it's been dry up until a trip a few months back.

I think the t-case breather is clogged and it's building up pressure, and pushing the oil out. How do you pull the breather? Can you reach it while it's still in the truck?

I found this pic when I had everything out of the truck, but I can't tell how it is attached to the case from looking at it. It's not mentioned in the FSM either.

I want to drive the 60 on a trip tomorrow, but would like to have this fixed first.

The breather is pressed in. If you can get a pry bar or chisel under the flange it should pop out.

Can you get to it while the transfer case is installed in the truck? I don't think so. One of the fixes is to tap the hole for pipe thread (1/8" maybe?) and then thread in a hose barb and then run a breather hose up into the engine compartment. I wouldn't want to thread the hole unless the transfer was disassembled.

If the seal is out between the T-Case and the tranny would it fill the Tranny too full and cause it to blow out? I know it is not uncommon on a FJ40 set up.

You may want to check the fluid level in your T-case.

You can get to it but it will be tight, and it will best be done by feel. One trick may be to lower the t-case by dropping the tranny crossmember. Support the engine under the oil pan with a jack, unbolt the crossmember, and then lower the t-case enough to reach the breather.

After rebuilding my t-case last year I drove for several months before reinstalling the breather. My plans were, and still are, to stick a hose on the breather plug and run this up into the engine compartment. Haven't gotten around to extending the breather so I reinstalled the cap with the t-case installed.
