4x4 / Off-Road TechThis section contains all discussion related to taking the FJ Cruiser in Off-Road situations, 4x4 applications and any armor modifications.
The FJ is touted as having the stock capability to ford 27.4 inches of water. With the rear locker engaged - that would obviously put the RR locker breather under water... hence the need for the breather mod, correct?
Assuming one performs this breather mod, what else should he/she be concerned about - if the water line is below the engine air intake?
I'm thinking more on the electronics tip. But I'm game to learn about other parts at risk too.
Secondly
Let's assume the ARB snorkel comes out and you slap one of those puppies on your rig. Then what? Let's say your engine compartment is completely under water but it's still able to breathe thanks to your new snorkel? I'd imagine several electrical components that would be at risk. Are there any true Scuba Drivers that have sealed off all of these components to prepare for this?

I read a thread where a guy was having dealership warranty issues because he had water in the transmission. He swears he never went that deep and does not have a snorkel but they listed his truck as "been under water". Not my idea of fun.

Yeah, that's the kind of crap I'm worried about. Believe me, I want to be part of the Scuba Driver club but I want to make sure I've done the research first before driving my rig into the deep

Unless they come out with a diesel that does not have all of the electronics as this, it will never be a true scuba driver. The electronic connections are all supposed to be sealed for water resistance, but I would not trust them.
You do what you can and every little bit helps when it is needed for water crossings.

Only if you plan on running in deep water allot. This is a normal means of relocating the diff breathers in the 4x4 community for many years like I stated in my original post.

Sensitive items have been located inside the vehicle passenger compartment. I remember in the old days we would use dry boxes to relocate some of our electronics in. The technology today has come along way.

I haven't heard of any problems, but with that being said, water & electronics does not go together very well. They are made under the hood very water tight. Again your driving an FJ not a submarine

Does the Tranny have a breather too?

Be aware that by doing this mod as described you are actually removing the oneway valve and replacing it with a paper filter. If you submerse the front end of the FJ, assuming you have a snorkel, the relocated breather will actually allow water into the differential. Removing the oneway valve eliminates the vacuum effect and prevents water from being sucked in past the gaskets around the axle, but it makes a two way path through the paper filter for air to move in and out of the differential. That's why it has to be placed up high out of the water.

You'd short out the battery and fuse boxes if the water level gets that high (the starter motor is not located that high either). Snorkels have air intake at roof level to mimimize dust intake. Diesel engines do not have spark plugs and ignition wiring so they are more suitable for prolonged fordings.
