Don't just fit breather kit do the job properly

Interested in this as have just fitted snorkel to my 110 300tdi defender and want to fit wading kit to finsish the job - So, why is a breather kit not doing the job properly - what else do i need to fit/do to do a proper job?

The breather kit is to go with the snorkel but it needs breathers on the following

Both axels
Gear box
Trasfair box
Timing case


All extended or replaced to as high as Posable normaly ran up the side of the snorkel

Also wadding plugs for the timing case and bell housing All of that together stops problems with water getting where it shouldn't
 
Dont need a breather on the timing case.

Yeah you do, the 300 loves to pull water into the timing case, it's ok if it's just water but when you start getting gritty, ****ty water in it can cause issues plus it rusts the timing gears and shortens the belts life...
 
Why should the 300 be diff to the 200, and why don't Landrover deem it necessary?


The 200 should also have a breather kit fitted and landrover do deem it necessary hence why that allow fitment of a wading plug. In theory the casing should stay sealed but it doesn't happen like that, it will suck in water through the gasket if you dont have a breather fitted, I have experienced it myself, I ran my old 300 without a breather kit at first and ended up taking loads of water out of it when I took out the plug.

As I said clean water is no problem really but if you start getting bits of grit in there and it will cause excess belt wear. You caqn run without breathers to the timing case but for the best protection you should fit breathers...
 
Landrover don't deem it necessary to vent the timing case, but it makes sense to do so for wading, especially when you fit a wading plug.

All enclosed parts of a hot engine/drive train that have gaskets can suffer from very quick thermal changes such as found when dipping a hot engine case into cold water, which can pull water and ****e past a gasket. A vent that has a breather tube located higher up allows the void to breathe and stops the chance of the thermal shock 'sucking' anything in.

Has to be said that any water, clean or not, is a problem and not a good thing to have, in any 'moving parts' environment. Water is not a lubricant and can emulsify the oils and itself so it becomes a very harsh environment for gears/moving parts to work in. Keeping water out, oil in yet still allowing fresh air in/out is the whole key.

i agree would rather air on the side of caution with something as ex[pencive as an engine, if its not required, well then its a bonus, but if it is and you don't have it, your buggered
 
Thanks for all the advice, i did do a search and from what I found out from that, the advice seems to be to fit extended breathers to each of

• front axle;
• back axle;
• gearbox;
• transfer box;
• bell housing;
• timing case;
• fuel tank breather; and
• injector pump breather

but none of the kits I've seen seem to cover the

• bell housing;
• fuel tank breather; or
• injector pump breather

Anyone know why this is - or if there is a kit that covers everything.

Also, has anyone fitted this kit: Breather and is it any good?
