diff breathers (80)

Hi Guys
I know , its me again, I have been under the cruiser looking at the diff breathers and have located the axle ones but for the life of me I cannot find the one for the gear box or the transfere box. I have located a pipe near the refill plug on the transfere but am unsure if this is the breather.
Where is the one for the gearbox.????
Where did you guys relocate the breathers to after you made them longer.????
Did you keep the valve on the top of the breathers and put them on the new hoses.????
This is the next thing I am going to do myself. Not so long ago I would not have even put a spanner to the cruiser, isn't life good when you have a wee bit of knowlodge. Thanks

Hi John,
Your best bet is to take a look at the tech pages on the LCool site -they have
some good picks and diags there.
Many route onto the firewall in the engine bay and then top off with a small
filter (you can use a small fuel filter) to keep the dirt out.
Personally I like the idea of joining up as you go along to bring you to a
single pipe plumbed into the side of the air filter housing.

John,
These breathers run on top of the gearbox and transfer box and are
exited into the engine oil dipstick tube.

a
It works but pipes must be joined up high enough (near the top of the
bulkhead) and be of sufficient internal diameter. Otherwise you may
end up with oil being sucked up by capillary action. How do I know?
Even though I had the winch oil reservoire manifolded at the top of
the bulkhead but it was done using 5mm ID tube - I ended up with oil
in the ... headlamps :)

Hi Roman
See this is what I mean about doing things to the cruiser when I dont have
the knowledge of mecanics or other professions the simplist of things can
cause issues through ignorance,(not knowing the knock on effect) thats why
im slightly nervious about tackling things on my own with no back up at
hand.
If the gear box and the transfere case exit into the engine oil dip stick,
is that not high enough for safety reasons.
What size are the pipes for the breathers and are they all the same.
To get at the gear and trans breathers do you need to take off all the
plastic protections under there.
A while ago I was bugging you about under belll protection and I was a bit
unsure about the out come of it all. I have not been able to get anyone to
do any work inregards to this as usual but I can sourse all the guards from
other places if I wanted them, but they are all in 8mm aluminium.
Is the aluminium or the steel better for protection under the body. Toyota
seem to think judgeing by whats there at the moment that plastic guards for
the transfer and gear box are fine. Thanks

Hi Roman,
I have noticed on some of the later LCs that they have small expansion
tanks on the diff breathers etc to prevent similar leaking from the
breather valves.
The breathers on mine has had the expansion tanks added prior to a join
to ensure there is no mixing of oil and avoid the problems that you
mention. Also the pipe work is a larger diameter and plastic based,
obviously part of some piping kit that neatly clips together.

John,
Here are a couple of articles that might answer some of your questions:

Yes if you have it fitted. It provides good protection from mut and
flying stones but won't be good enough for driving over rocks.
In general a TLC is pretty solid so unless you are planning a trip across
Africa or or are planning on going rock crawling you should be OK.
The type of protection really depends on the type of driving. If you are
likely to be driving over really rocky ground you might want to consider
a sump guard and also one for the back of the gearbox. You might also
want to get a steering guard.
Certainly for the time being I wouldn't worry about it.
8mm Aluminium is pretty standard for sump guards etc, just as long as the
supporting brackets are strong enough. Steel obviously is a lot better,
but also a lot heavier.
