If that is the case, a simple cap from a bottle positioned and held in place with a rim of suitable Silastic or similar decent adhesive together with it being connected to a rubber hose of suitable size, of small dia, would be quite effective. Just ame sure the surface is clean and grease free before the fitting.

Tom, PM me your email address mate and I'll dig up and send you the pics, you should be able to work out what goes where.

MD you really don't have to comment on every post mate.

The little black box is designed to prevent exactly what you are experiencing. It's IN from the diff should left alone and the OUT may be connected to a breather option if needed.

crumbdrakey??? Wow our Indian friends are getting a little more creative with their names. Even the comment is as stupid as usual.

Hello. I’m wanting to do my breathers properly on my dmax. And was wondering if someone could send me all the photos from the original post because none of the photos show up on the post. I’ve taken the console and other bits up and I can see breathers and what not. But just don’t know which ones for sure to block and which ones to run all the way to the engine bay. Thanks very much. My email is florihue@gmail.com. Would be much appreciated thanks

Once you get all the breathers hosed to the front somewhere suitable, if you connect them ALL to the same breather and filter it should be OK. However, you can fit an electric two way valve between breather and filter. With that entry point you can have a LPG gas regulator from a compressor to administer around 1- 1/2 PSI to the breather tubes when swimming. That wat it pressurizes all units so water is less likely to enter.
If the system is hot and then dunked, the breather system has to vent inward faster than the draw in of water through seals an everything breathes inward because of the sudden cooling. when the valve is turned off the breather system returns to filter vent of every unit. The positive pressure through the valve to the breather hoses, eliminates any water getting in as all units are at same low pressure which is around equal to the water pressure it is under.
Remember, the front wheel hubs are never included and so will draw water into the wheel bearings, especially if hot and then underwater, If swimming, Frequent checking of front wheel bearings is a good idea to see if there is water in there, A job I know but saves having bearings destruct way out in the back country. To me, the above is doing it properly.

Just trying to do my breathers and am wondering which one on the short tube is the transfer breather and which one is the one that goes into the cavity to breath. Thanks in advance

]You've probably already sorted this by now but this is from the instructions I wrote at the beginning of the post....Put all that aside for now as we now have easy access to the transfer and actuator breathers looking down through the hole.
-This is what you will see, only the "u" shaped tube that runs between the two large fittings I've already removed, the black line represents this, remove the tube and discard.
-The smaller tube 4mm or 3/16 (green) is the actuator breather, remove it also and block the hole, I just cut a piece of tube and filled one end with silastic and put it back on.
-The one circled red is the transfer breather, leave it open.
-The one circled blue needs to be blocked same as above


Unfortunately the photos I uploaded at the time that had the blue and red markings that would have answered this have gone missing. The way I worked it out from memory (it was 10 odd years ago!!) was I blew into them with a rubber hose. From memory the two at the left were connected and the one to the right was the breather for the transfer....this is just a guess and you would have to confirm yourself. The one on the far left is definitely blocked as it's from the actuator. Good Luck.
