Raised Breathers

[adrian]

Guys,

can anyone offer me some advice, i now have my snorkel fitted

and am now looking to raise the breathers to allow me to go deep water wading, i think the best thing to do might be to put the fuel tank and rear axle breathers in to the car? is this the best thing to do?

then i have to raise the front axle, transfer and gearbox ones.
there is a tube that comes up, and loops over in the engine bay, i assume this is a breather for something.

are there any that i have forgotten?
i have electric fans, so remembered that one.

plan is to start at 4ft, and then get deeper, sort ofcompetition with friends who have land rovers
(they are really popular here for some reason, but i will argue with anyone who things they are the best 4x4xfar! they will probably rust before they make it out of the water!)

but on land rover they have a wading plug that fits in the bottom of the timing belt cover to stop water getting in there, is there anything similar to this on the trooper??

just some big mud tires now and i'm sorted (for now at least!)

thanks guys, and keep on wheeling!

The only thing you need to worry about with the breathers is putting the dust cap's back on when you raise them. The front diff breather should already extent to the under bonnet. I brought the transfer case 1 up under the bonnet & the rear diff into the rear cab next to the wheel arhces. Besides the fan, thats all you really need to do. As far as i know all Isuzu's are pretty water tight (more so than my land rover & nissan!!). If you are doing them yourself make sure the hose you use isn't to flimzy as i found with a hot diff comes lots of suckyness that tends to suck the hose in & split it. If you have a snorkel i would also consider putting a purdge valve( if you dont already have 1) on the drain hole of the air filter. Hope this isn't to late..

Don't want to piss you off or that but there is also one on the gear box and it is worse to do than the tranny one, if you are going to do a body lift then do it before you try and you may not skin any nuckles if you are lucky, i just have a 8mm air line running fron the rear diff forward and just t into it where i need too, it then runs up in behind the brake booster thing.

Could sommeone please tell me if the fuel tank needs the breather extended?? i might have to look into that!!!

I think the fuel tank breather is sealed ito the intake somewhere Ive never heard of anyone anywhere modifing it. I havnt looked myself so this might be wrong. The early bighorns ran a shared oil resivoir for gearbox and diff and only one breather. I dont know for shore when it changed but if you have the 5 speed its almost definatly got 2 breathers. (mua5)

I shall have a lookat the fuel tank one day and see, got some more stainless tee's today!!
I wouldn't know when the beather set up changed on the gear/tranny boxes but i've got a 92 mu 2.8 and there is one for each, i thought the tranny one was bad to do but the gear box is worse and thats with a 35mm body lift!!!

[geeves]

The early 2.3 bighorns had a 4 speed that was a single breather Im not shore if the 2.8s ever used this box. All the Mus will be the mua box My 89 is also a mua but I dont know about moonmans 88 It is probably the mua so will need 2 breathers.
Dont do what I did to mine the first time I changed the oil. Found both drains but only one filler. 250km later I put it in low range and it squealed like a banchee. Luckily no permanant damage although low range is now not as noisy as it used to be

[mulover]

you are a huge pit of facts arn't you!!! you were lucky you didn't stuff something weren't you!!!!

[geeves]

There are some lessons that must be learnt the hard way. I was forced to drive 20km in low range and I thought my teeth were going to explode. My breathers still arnt done 5 years later even though it was water in the oil that nessecitated the change.

Have raised all breathers on my 88 Bighorn, but found no breather tube or cap on gearbox. Now pretty watertight. Re gearbox - check the rubber seal round the base of your gearstick where it goes into gearbox. If worn out this is the point that will take in plenty of water if you park yourself in deep water - which happens from time to time. Other thing to keep an eye on is that your rear pinion seal in front of rear diff, and your rear transfer case seal where driveshaft fits in are in good condition and not leaking. If there is wear there you will suck in plenty of water esp if dunking warm machinery in cold water. Well worth getting breathers and seals right as saves lots of time and $$ on new oils.
