Before I went for a play on the plains yesterday I fitted wading plugs to bell-housing and timing cover.....had a right laugh and got proper wet and muddy :D

Anyway....went to hose her down this morning and found the plug for the timing case missing :eek: What a bleedin eejit :doh:

Dont know at what point I lost it but the thread was none to clean.....

How worried do I need to be about me belt :confused::(
 
its just the belt, the tensioners and pulleys..

this is whats in there

as you can see, this is my old one (as cambelt was changed last month) completly caked in mud as you can see at the bottom of the casing... and I always, always use wading plugs (but this could have been previous owner)

I now fitted a double breathing kit on the timing case, as I think that with just the wading plug, it will suck air through the gasket/seals
 
hi new to the off road game so obviously any help to stop the engine going is most grateful, so what is a wading plug? just in the process of having to replace engine on mine so dont want the newer one going caput when my lad off roads it

thanks

there's loads of info on wadding kits in the forum, you can use the search function and find more.

but very quickly:

there's a hole at the bottom of the timing case, this allows oil to drain, when wadding you fit a plug there to stop mud going into your cambelt

there's also a hole at the bottom of your gearbox, wadding plug in there.

then you can also fit extended axle breathers and extended gear and transfer box breathers.

all this breathers already exist but are too short.
the rear axle breather, standard, ends just above the chassi, the front axle breather is attached to your front inner wing.
and the gear and transfer box breathers end just behind the engine, on the bulkhead.

look for pipes that are curved at the top, that's your breathers.

do a search though, loads of info on wadding kits, etc..
 
wots a wadding kit, JP - is it summat to do with guns?

yu can fit wading plugs and leave them in - just remove every oil change to allow any oil to drain and then refit.

nop.... you should always take them out.

water can be sucked through the gasket/seal when a wading plug is fitted as there's no other way for the casing to breath when hit by cold water, so it will stress the seals/gasket and suck air/water through there.

to avoid this, the best way is to fit a double breathing kit to the timing case. as when it gets hit by cold water it will suck air through the breathers and not stress the gasket/seals.

by double breathing kit I mean a breather in the timing case wading plug and a breather on the timing inspection cover.

Load of Bollix - i refer you to the LandRover workshop manual, that states "when fitted, wading plugs should be removed every 6000 miles to allow any contaminents to escape".
Not that Landrover know what they are for, of course :rolleyes:
 
that's for standard use.

I speak from what I experienced.

wadding plugs fitted and deep wading would always result with water coming out of timing belt casing when plug was removed.

since fitting breather kit to timing case, it never happened again.
 
when you get stuck and the water will be constantly on the timing case, like halfway up it or something like that..

of course the odd splash wont be a problem, but if you think about it, when cold water hits a hot casing, timing belt or axles, it will suck air in.
If there's a plug in the only place available to suck that air in, where will the air be sucked from? it will put stress on the gasket and seals as its the weak areas, and will suck the air and water through there.

if there's a breather going up, when the casing hits the water and needs to suck that air, it will go the easy route and suck it from the breather, therefore not putting any stress on the gaskets or seals.

just think about it as blowing instead of breathing.

you have a timing case, you stick an air compressor gun on the wading hole. put some pressure on it, where's the air going to escape from? - gaskets and seals as that's the easy and only route out...
if you have a breather..... the gaskets will be left alone and the air will escape through the breather tube

:D
 
yes, they are on 200s

Lynall... yes was probably that, dont fit a breathing kit, you dont need :doh:
thinking about it, i think it was the timing case that was fitted back to front lol

To late i fitted its ages ago, but was a serious suggestion as im sure the seal is fitted the opposite way to what you think it should be, ie garter spring on the outside as you are trying to keep the water out as opposed to oils in like normal.

This makes sense....the air in the housings has to be able to expand and contract so I imagine if you have wading plugs fitted permanently it has already found a way in and out.
Dont much see the point of 2 breathers though, is not like we're talking about large quantities of air so think I might drill and tap my timing inspection plate. Dont really like the idea of too much crap getting on the cam belt, guess it wouldn't cause any immediate damage but it must shorten its lifespan :eek:
